The sun in color photography.

The sun is very important for colorful landscape photos. We have paid attention many times, that reversible materials are adapted to this lighting, so that photos without the sun fall into slightly blue shades. They are also very flat and you can tell, they look "gray". We can take black and white photos of this type in accordance with the nature of the image. Gray and black shades harmonize with the content of the image, with color photos, however, we need to find more matching motifs, if we are to photograph them without the sun. In the past, there was a rule with color photos: "keep the sun not in front of your eyes but behind your back". This is not entirely correct, because the art of the photo is the best, if the sun's rays fall slightly from the side. Backlit photos can also produce expressive images. For example, leaves of trees in spring or autumn, through which sunlight passes, over pools of rippling water, they look much nicer on a slide projection than on normal prints or enlargements. Reversible materials are as if made for such effects, however, the selection of the exposure time is even more difficult than with normal photos, at which the range of usable exposure times is clearly greater. The brightest highlights and darkest shadows will be missing details, nevertheless, subjectively, the contrast will seem even higher to the eye. Backlit photos are beneficial, if we want to recreate the charm of the evening mood. We can meet very often, usually at the end of a read with transparencies, after seeing reversible sunset photos, with exclamations of delight. You can judge that, that there are no easier landscape photos to take than such moody photos of sunsets, which is being watched right now.

As long as the sun is still bright, we must hide from him, unless it hides itself behind the edge of a cloud, otherwise, we have to "set" a tree in the foreground. However, if the sun turns reddish and doesn't shine as bright anymore, then the same in the image with its high brightness will come out bright and not red. The exposure time, despite the approaching dusk, is still short, because we take pictures of certain motifs against the sky, whose foreground will be underexposed. About that, that this uneven underexposure could be prevented with half-height filters, we said above. When the sun hides behind the horizon, exposure should be extended. We can capture the last red glow of the evening only with an exposure time of 2-4 seconds., at the aperture 3,5. On reversible materials, it is recommended to take more pictures at different times for safety, related to each other as 1:2:4. Negative materials generally have a wider range of usable exposures, but still there are difficulties, in the correct reproduction of red, which is not so intense, as we imagined and wanted it.
