Particle photos of photographic techniques

Analysis of photo characteristics and styles

A photo with coarse texture is a photo with coarse image particles on the photo screen, which is similar to the special effect produced by screening when printing is enlarged, and is different from other photo types that pursue saturation and fine texture. Because the image particles of this type of photo are coarse and the density is not enough, the contrast between black and white is not great, the dark parts of the photo will not appear too dark and the bright parts will not appear too pale, and the color and tone of the whole picture are plain and soft, which is a more elegant and artistic photo type.

The reaction and discussion of the photography market

Generally, people who are unique and elegant can appreciate the style of this type of photos, and those who have studied photography have a special liking for this type of photos. However, some people who lack the concept of photography and art often can't accept the rough texture on the screen, and will think that this is caused by amateur or non-professional film shooting, and even think that photographers are suspected of cutting corners. Therefore, when taking this type of photos, it is best to understand the artistic quality of customers, so as to avoid self-defeating and futile.

description of key shooting techniques

1. shooting with ultra-high sensitivity film: this is the easiest way to get rough particles in the image. Those who like this kind of photos can choose high-sensitivity negatives, such as 8-degree or 16-degree film, and use a 135mm camera to shoot, and the effect will be more obvious when magnified. When developing photos, because the emulsion of the negative film itself is coarse particles with high sensitivity, it is natural to get a coarser image than the general negative film. Moreover, when a small negative is enlarged into a large photo, the phenomenon of coarse particles will be more obvious (the benefits of 135 film).

2. Use negative sensitization development method: that is, use sensitized negative film of about 4 degrees to shoot, and deliberately expose it less than second grade, and the underexposed part will be compensated by increasing the development time during the film development process. Because the negative film stays in the developer for a long time, the photosensitive particles will be coarsened, which is the commonly used sensitized development method. Those who use this method need to remember the exact number of underexposed files when taking pictures, so as to ask the printing company to compensate them according to the formula. Because the new negatives introduced by various manufacturers have quite detailed image quality, this sensitized development method is not effective; But in the past, it was the most commonly used technique in photography.

3. high magnification: that is, the effect of coarse grain texture is achieved by using the characteristic that the image grain will be coarse when the negative is magnified at high magnification. Generally, when the negative film is enlarged or the magnification is more than twice, the image particles will be coarse due to the enlargement, and it can be clearly seen by the naked eye at high magnification.

4. photos with the same coarse texture can also be obtained by using techniques such as coarse lens and screen printing. No matter which method is adopted, it is best to expose it slightly less than one file when shooting, so that the printed photos will be more coarse-grained (The dog head can be of great use ~ ~ ~)
