    How to Use

    Enter current settings
    Type your current ISO, shutter speed (as a fraction like 1/50 or decimal like 0.02), and aperture f-number. These are your starting exposure values.
    Step 2
    Choose your adjustment
    Use the slider to set how many stops brighter or darker you want the image. Then pick which parameter to lock so it stays unchanged.
    Step 3
