Is SLR shooting technology important or late PS important?

Yes, they are all important. Which one is more important depends on what you are shooting.

If it is a commercial or newsreel, the shooting technique is more important.

If it is studio work, wedding dress, photo shoot or something, PS is more important.

Let's answer your questions in order:

1, the camera shooting will not be better than the SLR, for the simple reason that the CMOS of the camera is too small, the color level and depth of field can't keep up, and the lens can't keep up, so the original image quality is not as good as the SLR. Late PS can only be done on the basis of image quality.

Therefore, after shooting the same theme, all PS and cards are much more than single comparison.

As for going out to shoot things, to release things, of course, you have to take PS, but PS is to remove bad parts of the picture, such as skin color, sky, contrast, not content.

2. The 2.RAW format can retain the picture level of 14bit, which cannot be realized by jpg. So there is no such software.

3. It is convenient to adjust photos with RAW, but it cannot replace PS. Generally do commercial shooting, shoot RAW first and then send it to PS intermediate tone.

For example, the skin color can be selected in PS, which is necessary for portraits, but not in DDP.

4, 800*600 resolution is enough. The general workflow is to use the original size film first, including PS. Output small size after adjustment.
