F-Stop and Shutter Speed Calculator
F-stop (aperture) controls the lens’s opening size. Smaller values (e.g., f/1.4) allow more light, create a shallow depth of field, and blur the background. Larger values (e.g., f/16) reduce light, increase depth of field, and sharpen the background. Shutter speed regulates how long the sensor is exposed. Faster speeds (e.g., 1/1000s) freeze motion, while slower … Read more
