Been very hesitant to put the message in which Edition, after all, this is the era of digital photo network, the trend seems to be irreversible, but, this is a pretty pitiful.
As of today, there are still many photography player does not want to abandon the traditional camera in hand, it is not the desired effect, and negatives taken by expressed charm, compared to camera's image, appeared to be more of a life; however, the popularity of digital cameras, compact survival of traditional cameras, when demand is no longer, there are more and more traditional film companies abandon film production line. In 2009, June 22, due to the high cost of production is not economically viable, and you need a professional print processes, global only remaining Kodak in the United States of a laboratory to provide service, Kodak announced the termination has a 74-year history of Kodachrome color negatives, accompanied by the National Geographic Channel's 「introduction Afghanistan girl "and" Kennedy assassination 」, sharp images, Kodachrome is the enemy of digital trends, along with Paul Simon song live forever in the hearts of the old photography player ... Your first time using non-digital camera history is what time?Light is the basis for photography, portrait photography, ray of light quality and light bits on the screen have a large effect, especially in portrait photography.
First, with a hard light shooting
The so-called hard light, are those that can produce light and contrast scenes surface in the shadow of the light.
This is in portrait photography, especially photography portrait of such subject matter when the light is rarely used. Hard light's greatest features is able to produce clear, shadow, difficulties is to control the screen contrast of light and darkness, and picture light ratio. Female shot generally light ratio control at approximately 1: 2, but using a hard light when shooting light ratio control in this area, almost impossible, the easiest method is to use reflective plate for supplemental lighting, through this diminishing character facial reflected light and shade contrast.Pictures from network
You can ignore the light ratio control law, and enhance the contrast of the screen, use light to the "story", with light to convey emotion, this is a hard light and other light, it is the expression of emotion pictures even stronger and deeper.
For hard-of-use, also note how environment to enhance modeling results. Also is to know what kind of environment you should use a hard light caused by the great light ratio, what kind of environment should control light ratio. Using a hard-light shooting, the importance of controlling exposure control. When the exposure can be too exposed half-level or more, to increase the contrast of the screen. Or less exposed half-level or more, although less contrast, but can bring down the whole gradation to express certain feelings.Second, use soft light shooting
Soft and hard light, on the contrary, those that are not in the character comparison significant light on the surface of the light.
When photographing women is always used, since it can obviously reflected character skin texture, make it more fair. Get the soft light of the method is simple, a piece of white bed sheets will be able to direct light into soft lighting. Curtain, white umbrellas, etc. are available as light soft Appliance. Soft light ratio control should be controlled at about 1: 2. And soft light for shooting zhongjin and those smaller than zhongjin composition, so that more prominent figures in the skin's texture. In addition to soft light filming the exposure level to level more than half, so can make the character's skin a more fair and transparent.3. used with light shooting
With light that is light to the people of positive projection light form, this light enables physique character of the majority were enough light and strength compared to the average, so does the character's face shape and dark contrast, exposure is better controlled.
With photographing disadvantage is light, and thus cannot be focused, so the album class portrait with very little. But with light is more suitable for shooting close-up and near such a little, because it can specifically performance figures in every detail and levels. Sometimes the most direct and straightforward description of results are often better than those who deliberately made do much better. Use with light exposure is not excessive when shooting, generally use average metering can get the desired result.4. shooting with backlight
Backlight is a light source in the rear light forms the characters, this light enables people facing cannot have normal exposure, thus Germany lost character's level of detail.
But this light forms the contour of the paint figure, reflecting the action and extremely beneficial to the body. Of course using the backlight will not have to take out the silhouette of the effect, if you control a good exposure, but also to get some of the details. Using the backlight shot silhouette, metering click where to shoot silhouette effect. To get pure silhouette effect, metering point can be selected in the figure on the edge of the body, where the light is the lightest in the whole picture. But those are not pure silhouette in the backlight effect, metering point you can choose to be the light illuminating the hair or the character's face. The backlighting effects in photo class portrait-style of the more common.Pictures from network
Backlight shot only suitable for zhongjin above King don't, such as panoramic or vision.
Because of this addition to the King don't reflect the character's body, but also to the environment for a degree of reflection, to enrich the contents of the screen. Shooting silhouettes, light projection angle to shoot out of the more obvious silhouettes, and light projection angle of the shot silhouette effect is less pronounced. So the time it is best to choose at sunset or in the morning, then shooting out of the silhouettes is the most obvious. And other environmental or other periods of light shooting out of backlighting effect, not that kind of pure silhouette effect.5. use the side-light shooting
A pure side light usually does not apply to photograph women, because of the light source from the side projection, so that the characters face half light, half in shadow, the effect is known as the "Yin-Yang face."
But in the photo-shooting class portrait, this light forms of use already not very fresh, often to more strongly reflect the character's personality and emotions.Use the side-light photography is important to note that the use of hard light, because the digital camera's tolerance is very low, if you use a hard light, the figures in the darker parts of facial details will not be any.
Use soft light is different, it figures contrast of light and shade the face in the digital camera's tolerance range, the shade transition more natural. Side light to photograph the King had a lot of the big King don't embody feel more strongly; while you can make the small stop being taken to become thinner. In shooting big King level, if you are using good light generated by the shadows, will enable the picture effect stronger representations.Side backlight is out from the backlight transform, characterized by an exposure to the character of a point on the face, while the remaining portion is not affected by light. It from the side rear light up the character's hair to render some emotional relief, but this light does not speak people positive details fade. Side backlight shot, if metering point in character facial part of are illuminated, the exposure to over expose level around in order to ensure the character facial details will not be covered up. King-the best choice in don't zhongjin following because panorama such scenes don't do not properly reflect the side backlight of light perception, but close-range or features like King, with side backlight to performance when compared to the full and lively.
Front light is determined by the side of the light and come out of a portrait modeling light, this light in most of the characters, the light of the transition are stronger, more suitable character modeling.
Use the front light photography can make people turn to the direction of the light source, this figure will increase the face of three-dimensional sense, but it is best to use soft light, to make the transition even more natural light. Note Select character facial shade transition zone metering, in order to get people of all levels in the face.Six, with top light shooting
Top light portrait photography is generally not used, but if we can use this light from above onto the feeling is good.
Top light from above directly to the upright people face, highlight the character's forehead and zygomatic, the outcome will be some terrorist. If you make the character move back to the light source de, and will head towards the direction of the light, shooting out feeling different.In addition, when the top photo, let people lying on the ground, than standing shooting results much better.
If you need to show them the light in character, it is necessary to give the feeling of overexposure, to strengthening through brightness reflected light perception. If you are shooting at noon, use to light white Occluder allows light to soften, then the effect is even more apparent.Pictures from network

Correct exposure knew seying
Correct exposure is the most basic shot snow is a key issue.
Snow is white Crystal objects, when its accumulation in the scenery, so that it becomes white, thus increasing the scenery of the shininess. There is snow on the scene some brightness is high, and no part of the snow is very dark, making sections of contrast is very large. Most of the digital camera its metering features reflective value is to obtain, so if you direct to the snow for metering, taken out of the screen will Dim, at this point you must make the exposure compensation to get good exposure.There may be some friends for exposure supplement this concept is not very clear, simple, exposure compensation is measured in the camera's exposure to increase or reduce the exposure.
Such as aperture priority of camera the measured exposure parameters to F2.8, 1/60 second, if you increase a retaining exposure compensation, auto exposure parameters will be changed to F2.8, 1/30 second, reduce a retaining exposure compensation, auto exposure parameters will be changed to F2.8, 1/125 sec. Different digital camera exposure compensation adjustment is not the same, use menu options are set through buttons. Not all digital cameras can be exposure compensation, then you can use manual mode to adjust the aperture and shutter speed, exposure compensation can be reached.We can look at a few different exposure value under the snow photos, first (shown in Figure 1) uses the spot on the snow for metering, taken out of the picture is very dark.
While the second one (as in Figure 2) the same metering mode, just add a block of exposure compensation, so that the restore is more snow. But you need to be aware of the exposure compensation cannot be increased too much, the third card (fig. 3) is increased by two guards, though the picture becomes brighter, but snow is not hierarchical.In general one retaining exposure compensation can achieve better results, of course, this also is not absolute, according to the scene of the environment, so after shooting a picture in a timely manner, the playback to determine the exposure compensation.
Note that not all the snow needs exposure compensation, only the snow in occupies most of the area of the screen is considered for exposure compensation. For example, the path of the photo (shown in Figure 4), do not add any of the exposure compensation, because the snow which only a small part.Light of acquaintance seying
Light photography played a key role in many cases we are unable to change the natural light, therefore we only wait for the light changes or a different angle and rational use of light.
Because snow is white Crystal, its shininess higher, of course, when the sun shines more brightly above.
Filming in the snow, if in a positive light or roof light for shooting, because the light flat is the relationship between exposure and vertically, not only does the white fine crystals have shading and texture, but also makes the scene out of three-dimensional effect. Therefore, in order to demonstrate a level of intensity and snow snowy transparent texture, using the backlight or back light shots snow most suitable. However, backlight or side light irradiation in the white area of the larger snow, not snow covered scenery of the other colors will be easy to be black, so in order to make snow in snow and other tonal scenes can be layered, photographing snow must select soft sun rays. For example the picture of small and medium-sized flowers Cheung Suet (shown in Figure 5) is the use of backlighting for filming purposes, then light in the background blur when shooting flowers highlighted, so that you achieve better results.Other skills meet seying
If you need to take a piece of sky snow dance photos, then you should select the darker background, so avoid background interference.
At the same time the shutter speed is not too high, generally at 1/125 sec or so, so snow scene of falling snow can form one line, snow's dynamic.Shooting people in the snow, you need the right plus auxiliary light.
Because of the snow as background will appear very bright, plus auxiliary light can reach the prominent role of the body, while the camera plus lens hood avoid other light interference. Polarized lens shooting in snow also have great role can snow reflection polarized light, decrease the brightness, you can make the sky more prominent, increase the saturation of colors.Third, the scenery photography composition techniques
Landscape photography composition operation is very important, there are six principles of composition:
1, balanced picture layout color symmetric or asymmetric type.
2, the size, high and low contrast, adopted near antithesis.
3. theme theme layout in the position of the screen.
4. pictures of connectivity
Picture of connectivity is from the line of connectivity and objects arise, there must be a dragon to pulse.
To Dragon is picture cited points to pulse is vanishing point, and performance, is a pulse to be found. In order to effectively demonstrate a sense of perspective.5. picture of rhythm
The rhythm of the main screen is a line from the scene, in view of the picture of lines, curves and diagonals buckling, arc, and bottom line, the line around the turning point, some are obvious, some of the solid line is the subtle dotted line; some are complex and ambivalent; some are simple and pure, but lively flow; some strong or weak contrast, some vigorous and effective.
These lines in our screen can effectively create a picture of rhythm and connectivity. Therefore, we in the scenery photography, must pay attention to using features of the line.6, picture of the cell style
In order to make the picture of the Royal treatment, or screen for sectional approach, designed to measure the screen layout.
4. prospects, zhongjin and application after King
Outlook: If you want to show on the screen, three-dimensional sense of perspective, the sense of depth, the prospects are very important.
If you are in the morning, sunset or cloudy, foreground color is darker, but if there is a Sun, and the foreground object color on the formation, and the prospect of 7 dark background and light look, which mostly backlighting photos. Prospects tend to be high, so the prospects of the treatment is very important to the success or failure of the scenery, for which photos future pay particular attention. Some scenery photo zooming is also coupled with prospects, enhance scenery photos of expressiveness.
Zhongjin: usually a piece of scenery photos of principal are placed in the foreground, so between the zhongjin zhongjin processing is also very important.
Some photos of you in zhongjin is tonal variations Centre districts that use Outlook and vision for the service, can achieve zhongjin express purpose of the theme, but the main location nor too median, and in the middle of the left or right side, so the more lively. If the principal in the Middle, it is easy to commit to four of the scenery all around, and get nervous, dull and lifeless.
Vision: vision of the role the scenery scenes extending away enough to express artistic atmosphere, enhancing the beauty of the picture, increase people's imagination and impressive, vision of tonal light tones, deep tone in tone and also, but very few.
But from the whole scene photos, not Outlook, zhongjin and vision, some only close-range and vision, some only zhongjin and vision, look for specific situations.
5. the choice of themes
Scenery photography theme is very extensive, with the exception of rivers, forests, fields and monuments, urban scenes, scene, night scene, rural landscape, lakeside Park and all natural scenery, and so forth, are part of the scenery.
Shooting scene photos and other content, before the shooting, first determine filming scenes for the topic, and then consider how to performance topics. This photograph is the only Centre, to express the author's intent. No one does not have a central content of the photos, even if the picture of how well the light, composition and how beautiful, how many levels, how fresh colors, and finally failed. As an article not Center content, make people look or boring. Therefore, the scenery works as required and write articles, chapters have method. Photos of light, composition, level and tone are all manifestations of the content of the technical means that is dependent on the content and cannot be used as the purpose of determining the screen.Often photography fans to see the beautiful landscape photos are asked to "shoot the photograph you waiting for?", in most people's minds, photos just like painting, music or literature, the expression of the creativity of a concept, but because it is built on the basis of the real image, if the foreground color and the screen in a more ideal light, like this concept photos must be "waiting".
For scenery photo, is the "first thoughts, or ideas taken from out-of-place" the problem of different photographers have different ideas.Pictures from network
First, the scenery of "waiting"
Still life or advertisement shot by photographer at the mercy of their own, built on the foundation of real Imaging Photography must have objective people or the environment.
Only in the field of observation and inspired, photographers to shoot yourself at that time feel. This is a photography and other artistic media, the largest differences between. In any other media art, both in painting, music, sculpture, and even literary creation, creativity can ability to play white f, the expression of ideas in his work.However, if the photographer want to exist in his thinking in the concepts shown in the photos, even if he waited long enough to show him this concept, nor necessarily shun his ideas appear in the eyes.
The situation was like a joke, said, "ask the guests a were absent, unwanted people are sitting on a table. "A photographer may also feel distressed, want to, not to the waiting, not expected to have suddenly appeared before him and got himself up. To change this situation by anguish, lies in the photographic discovery of play.Second, the scenery photography moments of
Photography is often referred to as the "moment of art", not only because of the photo shoot down the record just shutter open at that moment, but more importantly we have inspired theme, from its occurrence, development until disappears, may only be a short moment.
Because of this awareness, I often feel that the photographer's play can Zhi's "seven-step poem" to match. Historically, Cao Zhi in his brother forced, to seven-step in writing a song to portray the contradiction between the brothers, but not in the poetry of positive raised such a contradiction.Pictures from network
At the moment of photography, from happen here, it is our inspiration, and consider how this feeling expressed on screen, and then start operations and shooting until the situation of disappeared, the whole process can sometimes be better than taking seven steps takes time to come short.
For a humane society of the photographers shooting themes, the so-called ";" is most people are aware of the needs.
Use the "seven-step poem" to describe this pursuit seems more plausible, but also for most people, scenery photography is shooting a static theme, although the days are unexpected situation, but always to wear the "rain" in heaven, if you want to make a photo in landscape and light combined with more ideal, it is only to "waiting".Third, the scenery of the discovery of photography
At present, in general the habit of shooting, the focus of the landscape photography or establishment in the scene itself.
Light and weather at best only seen as enriching features theme "cosmetic". In the mind, looking for a few shots of extravaganza seems to become each scene photography enthusiasts of highest pursuit. If you do this, early fall late in a people shoot famous attractions to "waiting" to the ideal light, seems to be relatively easy to do. After all, apart from the seasonal changes, largeEffects:
Steps:

The following is the process steps:
Open the image, duplicate the layer, the image is yellow and dark.
Remove yellow and light is the most important work, and yellow I like to use the channel mixer, because I think it's image of damage are relatively small.But note that highlights some fairly normal, so we want to use mask protection highlights are not affected.
To the channel inside the Cymbidium channel load selection, because LAN channel in highlight areas more accurate. Then do a "select inverse" >.Figure 3
Returns the layers panel to create a channel mixer adjustment layer, first direct, the layer mode to color filter, we all know that screen you can mention bright image.
And then modify the channel mixer, double click on layer thumbnail, select the blue channel, because we want to fix is the blue channel, and green.Figure 4
You will find images to red, don't worry, then select the red channel, the red point reduction.
The two channel repeatedly adjust until satisfaction as well.Figure 5
Now available for layers, hair a little with its red around, find a more accurate recognition of hair selection, we select the blue channel to channel, blue channel load selection, inverse, create color balance adjustment layer, normally hair belongs to the shaded area, select the shadow, a little green, moderation.

Image color has been resolved, and then to deal with skin part, use the minimum value in combination with the curve for grinding skin on skin, do the following:
Copy the green channel, green channel copies for other > > "filter to a minimum value of the" value of 1.
Photographic composition is the first step, although photography composition rules is not dead, but understand composition can avoid some rudimentary error when viewing the good works, learn about the photographer why shoot, and their results must be of help.
This article on a photographic composition, although this article is focused on the composition of the landscape photography, landscape composition is one of the most complex, so armed with this rule, many can also be used in other types of photography.1. attractive scenery
Composition of a first step, we must first select an attractive scenery.
Photography is not a simply pick up the camera shutter, before you press the shutter, you have to ask ourselves, what this scenery attract you? is color? cloud shadows or sunset? ... Identifies the principal, the next step is how to get to the performance of it. Typically, the body must have adequate size, to stand out. The subject is too small, would not be subject, at this time will use long focal lengths, or late-trim to handle.Strange phenomena of nature can easily become attractive body.
This is a rainy evening, I note that the West sunset place no clouds, so I guess there might be a rainbow, so get to the Park, take this rare scenes.Shooting parameters:
CANON10D SIGMA15-30MM 15MM ISO200 F5.6 1/80 secSecond, avoid Center
Most of the beginners photography of mistakes that is the most attractive scenery is placed in the Center.
The stone cattle shanyunhai on photography: NET people
Indeed, in the middle of the scene is the most easy to attract people's attention, however, a good photos should be looked at to attract readers, to guide readers eyes to other place to go.
If, attractive objects placed in the Center, it is easy to only allow people to focus in the object, the picture becomes dull. At the same time, try not to make horizontal lines in the middle of the screen, because in that case easily lead to minor and non-obvious, do not know the key is to express the sky or the ground. But sometimes in the sky and the ground is just as important, I will put a horizontal line centered.III. composition of the rule of thirds
If you want to avoid the Center, it is necessary to know the so-called "two-thirds rule" (ruleofthethirds), also known as the "golden section", "9 bar Palace" ...
"One third rule" is the basic rules of composition, meaning: the screen horizontally in 1/3, 2/3 position draw two horizontal line vertically in 1/3, 2/3 position draw two vertical lines, and then try to put things on the intersection of location.
Pay attention to this picture, in front of the cow's location on the screen right 1/3, 1/3 position, if you put it in the middle position that makes it so compelling, and let the screen become dull.
This photograph of a horizontal line centered, I feel a little on the composition and has little effect, because the cloud and the following of meadows and cows are essential elements.Shooting parameters:
CANON10D SIGMA15-30MM 15MM ISO200 F8 1/180 secIV. use of prospects
Because we have two eyes, we see the world is 3D, but the photo is two-dimensional, in two dimensional photos express 3D is not an easy thing.
Our brain tells us: large objects is relatively recent, small objects is relatively far away, so that through the object size in contrast in the picture, you can feel out of the distance. In the photography world, Telephoto shot is the scenery of the ' compression ', wide-angle effect is reduced to a distant scenery, people have sense of distance. Therefore, in this occasion, we typically use a wide angle lens, proper placement of prospects to show a sense of depth.Travel photography mostly belong to the scenery of the winter photography photography, and photography at the scene is higher in the more difficult.
You need to be aware of and understand that:1, temperature and equipment
Due to the low winter temperatures, especially in snow conditions, the camera's mechanical system often experience a lubricating oil of coagulation exposure too slow, causing the shot out of control.
There are also dependent on the battery of the camera at a low temperature, power will soon be depleted, causing no shooting. Solution: try using purification machine manual models, such as home-made of seagulls, Phoenix, Nissan's Nikon FM2, de production Leica R6.2 (Leica R6.2 at minus 20 degrees guarantee speed), and so the camera even without power, so they cannot metering, grasp data capture no problem, of course, the best equipped handheld light meter. The majority of current camera for automatic camera, it should try to put the camera on his arms. Can an ordinary lithium batteries would not have batteries, lithium batteries and common cold than to battery. When longer time in the outdoors, camera temperature is low, once inside the warm room do not open the lens cover, to avoid condensation.2. snow and ice and exposure
Winter photography difficult to difficult exposure, due to the reflective ice and snow with high rates of all camera in metering is design to 18% of the reflectivity of the snow and ice, so make absolutely normal metering is not accurate, this case in automatic mode will make film underexposed, the solution is often to increase the exposure 1.5-2, currently marketed cameras generally have +-and other functions.
If not, you can set the aperture metering f16, speed 1/125 sec, adjusted to the f11, 1/60, or change the speed to 25 ASA100.Outdoor portrait photographs adopted a different composition and perspective, plus the models of clothes and make-up, can take out all the beautiful people feel the tranquility of the photo.
Through the large aperture, low angle, using the foreground blur, diagonal composition, composition, and other methods are the framework can enhance your work. 1. portrait photography in the portrait photography of significance is the subject of "people", the screen selection should be based on people, whether taken photography and skills will still be with us to focus on "people". 2. When you're shooting a portrait of note is the main attention model of? the emotions, the combination of man and the environment, as well as the on-site application of light. 3, photographing portrait you pay most attention to? how to catch those moments was being taken, as well as light and shadow effects as well as the surrounding environment. 4. How do you communicate and model each shot,? especially first cooperation model, dont shoot, model first and make the necessary communication, photography themes, content, methods, and requirements. 5, the same scene, how to shoot in order to maintain passion each time? at the same place, shooting a scene, multiple times, to follow a different feeling films that are very difficult. It is on this site know, coupled with the think through such shooting to exercise to improve the skills of master in photography, to keep shooting passion. 6, outdoor light grasp? can take backlight shot method, the pursuit of light and shadow effects. Overcast, light meek, if the scene environment and character together better.7. is there a good shooting angle recommended? model squatting in flowers, take down Pat or low angle of approach, highlighting model and flowers or plants.
You can also use lenses telephotos models came out from a tree, highlight the relationship between people and the environment.Many digital SLR sensors than 35mm film area is small, a typical digital SLR CCD sensor length ratio of slash 35mm film small 1.5 times.
Typical 600 million pixel digital SLR sensor size (43.3/28.1, slash length than 35mm film small 1.54 times)
Therefore, smaller than 35mm film sensor only photographs of the central part of the film, causing the loss of the "vision."
A 35 film camera need a sticks of focal length larger lens to achieve the vision of the digital SLR sensors. 35mm film slash length and the ratio of the length of the sensor slash is the focal length multiplier (FLM). Let's take two examples of FLM: example 1: digital single lens reflex camera with 35mm film uses the same focal length lens film camera lens imaging sensor 200mm focal length coefficient FLM 1.5, obtained just 35mm camera to the camera and lens 200mm central part, led to the "vision loss", which is equivalent to 35mm camera 300mm lens out of an image (200 x 1.5 = 300mm). The absolute size of the moon does not change, because the focus is still 200mm Example 2: digital SLR film cameras use than 35mm focal lengths shorter lens film camera lens imaging sensor 200mm focal length coefficient FLM 1.5, due to the use of focal length shorter lens (133mm, 200mm/1.5), digital SLR camera is obtained to 35mm 200mm lens cameras to get the full scope of the image, which is equivalent to 35mm camera 300mm lens out of an image (200 x 1.5 = 300mm). The absolute size of the Moon, because of the shorter focal length lens. (Magnification)This means that if you put a mm lens mounted on the digital SLR (FLM 1.5 times), it produces a range of perspectives in fact equivalent to 35mm film camera 28mm lens.
However, the shortcomings of the wide angle end sometimes conversion growth Coke side edge. For example, put a mm lens installation in digital SLR, it vision range equivalent to 35mm film camera 300mm lens-300 mm lenses are often more expensive than 200mm. It is precisely because this focal length doubling effects, digital SLR easily to a shorter focal length, the greater the depth of field.Specialized lenses for digital SLR
Most digital SLR will be able to use the traditional 35 mm camera.
Nevertheless, these programs would have to 35mm film cameras manufactured than the film area small sensor, the lens is too big and too heavy. Digital SLR dedicated lens (Canon short black lens, Nikon DX-series cameras, Olympus 4/3 system lens) than traditional 35mm SLR lens light, because their lens ring size as long as they meet the needs of the sensor.On a small digital camera
In order to adapt to the small sensors, creating a good 35 mm equivalent vision range, small digital camera lens is usually shorter.
Typical small digital camera sensor length ratio of slash 35mm film 4 times smaller. Small digital cameras marked "7mm" focal length lens, equivalent to x 4 i.e. 28mm 7mm. With the digital SLR, the camera lens ring size as long as they meet the sensor coverage on it, so they shot a compact and cost less. As a small digital camera lens focal length is short, so it's better than digital SLR and in the same 35mm camera vision range, greater depth of field.
