## Source

Choose the colorspace of your “log” or “scene-referred” footage or working space.

It is not technically possible to produce accurate diffusion from “display-referred” footage but we have included the “(Inaccurate) Gamma 2.4” Source option which may produce a useful approximation on generic Rec.709 or sRGB “display-referred” source footage or graphics.

## Family

Select the family of profiled filters.

Here is a comparison of each filter on a bright white source:

## Strength

Select the strength of the selected filter family.

## Intensity

Amplify or reduce the effect of the active filter. Modifying intensity is not necessarily the same as selecting a different filter strength since some filter families do not have consistent characteristics between strengths.

## Focal Length

The size of diffusion falloff typically varies with the field of view of the lens/sensor. The profiled filters have been calibrated for a 50mm lens on a s35mm sensor. This slider reduces/enlarges the falloff to approximate other fields of view (expressed in millimeters of focal length on s35mm).
