How to realize the large aperture of digital camera? What if there is no adjustable aperture?

Analysis:

It is good to have the aperture function to adjust directly, which is not a strange setting in digital.

Without this function, there is usually only the automatic program file exposure function of digital images. So whether the aperture can be adjusted depends on whether the program file has the offset function.

The program offset function is as follows: after the camera automatically gives the exposure combination, if the aperture size and shutter time do not meet the photographer's requirements, start this function, and the camera will give several choices with the same exposure but different combinations of aperture and shutter values in turn. If the original automatic exposure combination is F5.6,1125 seconds, we think its aperture is not large enough. If we start the migration, we will get F4, 1/250 seconds and F2, 1/65438 forward.

If there is no program offset function, there is generally no way.

But if the camera has a lower sensitivity option at this time, it should be adjusted to the lowest gear, and you should get a larger aperture than before. This is an unpretentious remedy, and there is no way. This is just a trial, there is no guarantee.
