Would like to understand how to meter(adjust shutter speed/aperture) for proper exposure when using on camera pop up flash(the one that is default on most dslr) when shooting in M manual mode.
Quickly looked up online and could understand that the recomendation is to use large opened aperture and high iso. Would like to know if we need to adjust the aperture and shutter speed to get a balanced expore as we do elsewhere while shooting in manual mode.
Or is it that the exposure is automatically adjusted by the camera itself as soon as it detects that the flash is allowed to fire.
Thanks in advance.
