How to create image effects of coarse particles

Photos of coarse particles are absorbed by the body, but the photographer subjective a special technique of expression, which can result from photography and photographs of the post-production process. In General, the requirements of the particles of thicker photos, the more complex the production process. Here, the black and white photographs and color photos have the effect of coarse particles respectively manufacturing method. Black and white film speed and display photos of coarse particles are absorbed by the body, but the photographer subjective a special technique of expression, which can result from photography and photographs of the post-production process. In General, the requirements of the particles of thicker photos, the more complex the production process. Here, the black and white photographs and color photos have the effect of coarse particles respectively manufacturing method. Black and white film speed instead of showing the proportion of particle effects, the PC slower, more delicate particles; PC faster, more coarse particles, shooting to select high speed PC film. In addition, you can change the film exposure, and the conditions for developing Coarse particle effects. Shooting is not enough to let the film emulsion, then when the developer to developer heating and extension developer time, enhanced developer, you can make the film grain coarsening. However, even using the above method, if the last production photos, photo size and film, and other large or greater, coarse particle effects are not reflected. Photos of higher magnification, the more coarse particles, effects. If you want to adjust the composition, conducting local amplification, coarse particle effect will be more obvious. Color photographs on the composition of the particles is not a metal silver, but the color blocks. Effect of coarse particles tends to make the photos become like works of the Impressionist stippling. Color film and black and white film, photographic faster the particle effects are significant. However, because of the color of color films is very fine particles, it is difficult to make general method for coarse particles. In order to achieve the desired results, you can use the following two ways: (1) zoom in photographing method. The first color original bottom placed a huge photo (from the film of a local effect better), and then photographing the close-up photo of part of the screen on the resulting regeneration negatives then fangzhi, the screen will show a very coarse particles. (2) micro shooting method. If you want to put the negatives of partial discharge obtained greater, you can make use of a microscope. Of course you also need a single lens reflex cameras and tube for direct from microscope camera have been enlarged several times or even a hundred times the original negatives of partial images. Get the film image magnification than the original film, many times. colorful dot Of course, both black and white or color photographs, are available through another mechanical means to obtain a coarse particle effects. Zoom in photo, in film on a coarse textured (or film clips in frosted glass to zoom in), so the effect is often good. (Norway) Jens · Hagen photo
