Golden Hour & Blue Hour Calculator
Find the exact golden hour and blue hour times for any location and date. Photographers use this to plan outdoor shoots when warm, directional light is at its best.
Exposure Equivalents Calculator
Find equivalent camera settings that produce the same exposure value when you change aperture, shutter speed, or ISO. Useful any time you want to swap depth-of-field or motion blur without altering overall image brightness.
Equivalent Shutter Speed
0.4 s
At 0.1 s and longer, motion blur is unavoidable handheld. Use a tripod and remote release; subjects moving during a 0.4 s exposure will streak.
The equivalent shutter speed comes from the reciprocity formula; these bands reflect the photographic rule that handholding usually requires faster than about 1/60 s (0.0167 s).
