Why does the adjusted SLR camera darken? Dark photo

1 If you use the manual mode, that is, the M file, and all parameters are fixed, then the more you shoot, the darker it may be affected by the change of ambient light.

If the shutter is fixed first, the aperture will increase automatically after the ambient light darkens, but it will become darker and darker after reaching the maximum aperture of the lens.

If you use aperture priority or other automatic gears, this phenomenon should not occur.

.

In short, the dark photos should be caused by underexposure. The factors that affect exposure are aperture, shutter speed and sensitivity. As long as these three parameters are properly adjusted, the correct exposure can be guaranteed.

There are no fixed shooting parameters, and all the parameters are adjusted for a certain shooting. When the shooting environment light and the position of the shooting object change, the parameters should be adjusted accordingly to find the most suitable parameter combination.
