Formula and method
This calculator uses the values you enter and applies the calculation immediately in your browser. The main output formulas are:
- Exposure time:
angle/(360*fps) - Approximate shutter denominator:
360*fps/angle
Some formulas are undefined for certain input combinations, such as division by zero, equal x-values in a slope calculation, or logarithms of non-positive numbers. In those cases the live tool reports that the result is undefined instead of displaying Infinity or NaN.
Examples
- Example: with Frame rate = 24 fps, Shutter angle = 180 degrees, this calculator returns Exposure time = 0.02083 seconds, Approximate shutter denominator = 48 1/x.
