Have you tried upping the ISO? The amount of light need to capture a image is constant. The amount of light need does not change unless you change the sensitivity setting which is the ISO, changing from ISO 200 to ISO 400 change the amount of light needed by 1/2, change from ISO 200 to ISO 800 the amount of light needed is 1/4 of what it was at ISO 200Originally Posted by pinkmotherofpearl
The correct exposure is determined by the F stop and Shutter speed. If you stop down the lens on step you have to double the time of the shutter to keep the amount of light the same.
