Selecting the Pre-Divide/Post-Multiply checkbox will cause the image’s pixel values to be
divided by the alpha values prior to this conversion, and then re-multiplied by the alpha value
after this conversion. This helps to avoid the creation of illegally additive images, particularly
around the edges of a blue/green key or when working with 3D rendered objects.

Editing the Log-Lin LUT
The Log-Lin LUT lets you apply a Log to Lin or Lin to Log operation using the Mode pop-up
menu. You can choose the type of log-encoding to process from the Log Type pop-up, and
choose whether to lock the R, G, and B channels together. A level adjustment lets you redefine
the digital range of values used for the output, while Soft Clip (Knee), Film Stock Gamma, and
Conversion Gamma sliders let you further customize the color transform. Lastly, a Conversion
Table field and Browse button let you add an additional LUT as part of this operation.
