ISO sensitivity filter

Description

Filter This filter is similar to the Gain filter, but conveniently applies the gain defined by an ISO Standard Output Sensitivity(SOS), corresponding to the user-selectable gain on a digital camera, considering that input buffer contains XYZ exposures values in lux·s. This is true with standard camera instrument models such as Ideal rectilinear camera used in conjunction with XYZ observer spectra.

Input and output

  • Works with any input channel.

  • Output channels are the same as input.

  • Does not alter the buffer dimensions

  • Preserves denoising meta-data
