The product photos taken by my Canon EOS600D are fuzzy, with no texture and luster. What happened?

Although you don't have the picture above, according to experience. The causes of blur and lack of texture are analyzed as follows

1, high iso, resulting in more noise and no details in the photo.

2, shooting in low light, the shutter speed is slow, and the hand is shaking, so the film is also burnt.

3, mode selection, Canon camera has m Av Tv and P files, which are full manual, aperture priority and shutter priority respectively. Wrong choice, a default parameter setting is not good, the film will not look good.

4. You chose manual focusing, and there is an AF and an MF on the lens. The former is automatic and the latter is manual.

5. The focus mode is selected incorrectly, which causes the focus to shift when the shutter is pressed.

6. There is no half shutter composition.

7. The most tragic thing is that there is something wrong with the camera body or lens components.

Please keep asking questions.

Supplement: the metering is wrong, the aperture is too small, the composition is too dramatic, and it is a bit overexposed.
