Advanced Options
Colorspace	dropdown	The colorspace the image data is converted to. Automatic is determined by the file name, size, and type of data in the channel. OCIO colorspace roles are also displayed in this list.
Alpha	dropdown	• Premultiply - If there is an alpha channel, divides color data by the alpha before converting from the colorspace, and then multiplies by the alpha afterwards. This corrects the color of the partially-transparent pixels produced by most renderers. • Leave - Does not premultiply. • Remove - Imports only the RGB data, discarding the alpha channel altogether.
