How does SLR delay photography?

M gear, ISO manual. Normally, the aperture should not be too small. Although a small aperture can bring a large depth of field, it will also bring dust marks on the lens and CCD and diffraction of light. F8 is a suitable breakthrough. White balance is manual, which can be preset or adjusted manually. Close the fuselage for high-sensitivity noise reduction, and close the fuselage for automatic dark compensation.

The shooting delay is mostly m-file manual mode shooting. Because shooting in M manual mode can be accurately controlled by the photographer himself, the brightness of the front and back pictures can be guaranteed to be as consistent as possible.

However, the disadvantage of M-range manual mode is that it is not suitable for scenes that change greatly before and after shooting. It is typical to shoot from day to night, because as time goes on, the light will get darker and darker. After using the M-range manual mode to fix the parameters, the picture will soon darken as the light weakens.
