What factors in SLR photography can't be compensated by post-production, only depends on the lens and camera and the photographer himself (the shooting technology is better)

Shooting skills, put aside here for the time being. Because creativity is too complicated. There is no conclusion. If you miss this scene, you may never come back.

Composition is also a skill category, but the failure of composition can be made up by cutting.

First of all, talk about the quality of the camera. I think ISO and focusing can't be made up later.

1, in a bright environment, there is really no feeling in a lower environment. However, if you switch to a dark environment, such as bars, concerts and night scenes, you need to adjust ISO to a very high level. At this time, the difference between an entry-level computer and a professional computer appears.

2. also, focus. If the focus is not in focus, it will always be in focus. Paste is paste and can't be ground any more.

3, what multiple exposures, what HDR, can be achieved later, but it is a bit troublesome. .

Second, talk about the quality of the lens. Anti-shake, aperture size, sharpness, color, focal length, phase difference, anti-glare ghost.

1, anti-shake, I think it is very important. At least in the absence of a tripod, you can slow down the safety shutter speed. Ensure the clarity of the image.

2. The aperture size determines the depth of field. PS also made the effect of shallow depth of field. However, excesses are unnatural. But now there seems to be such a filter.

3, sharpness, in fact, can be adjusted later. But the natural sharpness in the later period is hard to achieve.

4, color, color can of course use PS tone. But rich colors will be unnatural. Because the color resolution is not high, similar colors will be displayed the same. Well, you can't change the color with PS.

5. The focal length, spatial stretching and compression of wide-angle lens and telephoto lens cannot be adjusted under any circumstances in the later period. Well, I can only experience it myself.

6. The phase difference is deformation. For example, the fisheye lens will shoot a straight line into an arc, and of course some wide-angle lenses will do the same. PS can easily bring out such an effect, but it is difficult to correct it. So a high-quality wide-angle lens will be expensive.

7, glare ghost, this, some people like it, some people don't. But it's even harder to remove the real thing from the photo.

8. There are also some special lenses, such as shift lens, macro lens and fisheye lens, which have peculiar imaging effects. The effect of the shift lens may be calculated now, but what about the macro? Generally, the lens can't be so small, and the PS can't be so big.

Seeing your supplement, I said that someone can draw. Of course, if you can draw and you can p, then I'm talking for nothing.

The above content only provides a content that is easier for ordinary graphic designers to shoot than PS.
