Why is there color difference in the photos taken by the camera? It was taken in the shed. There are two pairs of flash pants. The camera is Canon 7D.

In fact, color difference comes from many aspects. . For example:

1. White balance

2. lens

3. Photosensitive element

4. Color difference of display screen

The influencing factors of white balance are divided into external lighting and internal camera white balance system.

Generally speaking, as long as the lighting conditions and the lighting conditions in the camera settings (for example, shooting in sunlight under normal sunlight) can solve the problem of external factors, it is really impossible for you to shoot in RAW format, and adjust the white balance with Canon's own software after shooting (you can set it from 2000- 10000, which is the software in one of the CDs you bought from the camera, and it is quite easy to use. Be sure to try and adjust the RAW format without loss. The camera can.

The internal factor is the chromatic aberration of the camera itself. For example, Canon is warmer yellow, Nikon is colder, Pentax is greener and so on. For example, a lens is good for red and a lens is good for green. If you want to change this problem, you can only use PS to adjust the colors one by one. Specific settings, open PS, press Ctrl+U to enter hue/saturation adjustment, and there is an option (default full picture) at the top left to select the color to be adjusted, and then adjust it until you are satisfied.

The influencing factors of display should also be divided into hardware and software. Hardware refers to the color difference of the display itself. Generally speaking, Apple's monitor is the most active color in home monitors. Software influence refers to what software you use to look at pictures, with the picture browser that comes with windows, with PS and with web browser. There is a difference between chromatic aberration and sharpness, so you can see for yourself. The influencing factors of monitors are the most uncontrollable, because the monitors of buyers are different, and it is impossible to say that everyone sees the same color.

Therefore, the so-called chromatic aberration, as long as you control it within a small error range, is not outrageous, and the error is always universal and must exist. Let's go

Besides, as a photographer, I'll give you some advice. Don't hit one left and one right with two lights, it will make things very flat and have no texture. You might as well turn down one of the lights and hit it flat on your pants, which will produce a certain shadow of detail, and adjust the specific degree yourself.
