Film speed and photographic equipment

According to the film speed, we can put the film into three broad categories: fast film. Slow-speed film and film. Fast film with high ISO (International Standards Association). Slow film of lower ISO values. Fast film applied to the photo under low illumination. In contrast, when the PC performance low slow film may cause underexposed, fast film get the correct

According to the film speed, we can put the film into three broad categories: fast film.

Slow-speed film and film. Fast film with high ISO (International Standards Association). Slow film of lower ISO values. Fast film applied to the photo under low illumination. In contrast, when the PC performance low slow film may cause underexposed, fast film the possibility of obtaining the correct exposure is even greater, however, the speed improvements will reduce image resolution to increase the contrast. Slow film in illuminance good, get high-quality photos are very favourable.

Film force Developer: If you take additional extended color negatives of developer time to compensate.

Color negative film can press calibration ISO values for exposure of 2 times. Slow film: this piece of marble bust statue of photos is to use slow film (ISO32). Please note that the statue faces delicate beige texture as well as bright and dark on the right is left soft tonal transition, even if you zoom in, the scene of the particle size is also negligible. Slow film selection: slow film suitable for shooting a bright was taken, or where the record is taken of the dynamic and fuzzy traces. It is commonly used for still life photography, because still life photos need to zoom in on details of fullness after remains, particles and exquisite images, even in bad lighting conditions, but also to put the camera is fixed to a tripod for slow-speed film for a long time exposure. Medium-speed film: this is the top lighting conditions unchanged, use of medium-speed film (ISO200) filmed half statue. Note that the film of the PC faster, more coarse particles of the image. At this point, the film's PC much faster (ISO value doubled, said the PC performance improvement 1 times), but the image quality remains satisfactory, particles are not obvious. The choice of medium-speed film: medium-speed film is suitable for a wide variety of camera body and a wide variety of lighting conditions. For the Eastern Mediterranean scenery photo, its surrounding environment brightness is high. But will still be available in the morning or evening when the Sun is a little low and not very strong sunshine with medium-speed film. Fast film: when the film speed increased to ISO400, the whole half statue of the slightly different. The face is not enough, half-length, light and dark's fat poor start. As expected, with a speed of the film, the image is enlarged by man-made materials is obvious. Selection of fast film: shoot this flying seagulls need high-speed shutter speed to capture the sense of being perturbed and prevent camera shake, at the same time, the need for a small aperture, avoid focusing on errors. Fast film can make you very dark weak illumination crawl was taken. Ultra-fast shooting this film: to use as the statue of the film, its ISO1000 photosensitivity is ISO400 film 1.5 times at this point, the film emulsion of particles very significantly, at the same time, please note that when using a slow film very gentle gradation level now more rough, but the color is changed. Ultra-fast film selection: the lighting brightness is very low, for example, in a dark room or the weak and the evening of outdoor, optional ultra-fast shooting film. This film is very sensitive to light, even in the matches to light was satisfied with the results. Their visions of a particle size can create dramatic screen, get remarkable atmosphere.

Basic photographic equipment

On 35 mm single-lens reflex camera users should have a set of photographs of various kinds of equipment and accessories.

On the lens, your camera can be supplied with an installed 50 mm standard lens. In addition, you should consider is equipped with a 28-35 mm wide angle lens for shooting a square surface or in narrow places. 90-135 mm telephoto lens for shooting portraits and distance of scenery is appropriate. The zoom lens flexibility, avoid the transform lens brings trouble. Tripod in guarantee static scenery images clear at the same time, the long exposure time to prevent camera shake plays an important role.

If your photography packages there is room, you also should be placed some filter, a set of basic camera cleaning tools, a pad of paper and a pen.

A portable Flash and spare some different ISO film. Shutter release cable for fixed in tripod camera shutter and avoid camera movement. Filter: lens UV absorption installed a filter, the lens has a protective effect. Coloured filters for black and white film or color film special effects.
