What is the shutter Speed Camera is needed?
A camera takes a correct exposure at f/5.6 and 1/125s. What shutter speed should be used if the lens is changed to f/4.0? 5.6 and 4.0 are the diameters of lens I tried to use the report 5.6/125 = 4.0 / x to x resolution and got the right answer
1 / 250 second. You can not use your formula, because openings are measured in a linear fashion, but to transmit to the square. F / 4 transmits twice as much light as f / 5.6, not 1.4 times as much. Therefore you use half the time shutter open much.
