"its torrent dashes down three thousand feet, suspected Milky. "Whenever we see a waterfall, you just can't think of the look of the Tang dynasty poet Li Bai lusan in this period of history of the horror genre. In fact, in the nature of water not only falls, there are many types: or flowing stream, or Pentium heroic rivers, or lakes that static looking ... Before you know it, they all give our living environment has added a lot of Swarovski. However, natural water features while we see it seems very good, but you want to use a digital camera to shoot well, but it is not easy. We put the camera in question set out, one by one to make targeted questions. ◎ Issue 1: exposure control what needs attention? many photography enthusiasts tend to flow into a pure white, on the surface seems to reflect the essential characteristics of the water, but in fact not true. In fact the water in the objective circumstances of color is the effect of the surrounding objects, even if it is completely white parts will be according to the intensity of light illumination of showing a different tone, i.e. water from white to grey is full of delicate details change. Shooting not only manifestations of stereoscopic effect, but also on its inherent texture make interpretations do this prerequisite is the need for accurate exposure control. How to achieve accurate exposure control? here with "18% gray standard" concept, that is, if you are panning of reflectivity is about 18%, then the digital camera is able to accurately metering. But natural waterscape shooting composition full of various colors, both have very low reflectivity of deep tone, there is a high-reflectivity color, so when shooting water features, the viewfinder in rich colors together. If the screen colors together, probably will be in grayscale, press the camera of beta-General will receive the correct response. But some time for performance of the evening's atmosphere, or special needs of a shadow, you can transfer to 1/3EV as appropriate to reduce the exposure until you achieve the desired effect. Otherwise, unless the screen contrast is very large, typically-1.5 EV ~-2EV can meet the requirements. Before the shot was taken should be carefully considered and composition of rocks, plants and other dark scenes and flowing water, sky, light-coloured part of the ratio between. The composition of a picture, the dark parts and light-coloured parts essentially have equal shares, the whole picture grayscale gradation, approximately 50% gray, considerably more than the normal metering 18 per cent digital camera gray standards so that results will lead to the camera for picture composition, you need to compare the dark dark objects reached normal gradation, self made the decision to increase exposure compensation, see Figure 2 results: rocks, plants and other dark scene although exposure to normal, but the flowing water, sky, light-coloured part of the already serious solarize, lost its inherent detail and texture, and levels of the stereoscopic effect is gone, and we thought to performance results. Incorrect exposure, highlights of rocks and plants, and water lost detail. The solution is usually more use of multiple district average metering to central spot metering or spot metering, measurement of the object it is best to choose both a white flowing water and Black Rock (or in the shadows of water), and the ratio between the best control in 1: 3-1: 4 or so, and then set the lens to the telephoto side, allowing measurement of area completely filled with the viewfinder when the screen white and black mixed up about 18% gray. Although plants and rocks in the final screen will appear relatively dark, but water sense got a very good show, blue sky color also appeared, in particular through the branches of the ray of sunshine, thin and sprinkled on the effect of light on water, light and gentle ups and downs, and poetic. If you still use multiple district average metering, you need to reduce more exposure so as to achieve such an effect. Correct exposure, flowing gauze-like texture was very well presented. The horizontal location best? รข 2: horizontal plane of the location where the best when shooting landscapes photos? inevitably encountered a more difficult issue, that is on the horizon. Especially when shooting in the sky as a backdrop of sea and steppe, a straight, no rhyme line across the screen, if not handled properly it will seriously affect beauty, filming the screen to water-themed scenery photo, of course, also have the same problem. The usual solution is to use the golden section method, the horizon on the golden section, which is the approximate average picture vertically into three parts, the horizon is located at the top and bottom two bisector, as it is on the golden section line or by the golden section, according to the performance focused on the above scene (days, plants, etc.) or the following scenes (ground, water, etc.). Unless you specifically request, it is best not to tilt the horizon or picture is placed in the middle. The water in the picture below one-third of the way, to show the foreground and background of abundant levels very favourable. Scenic photos of common patterns, most PE elements
