Description

Based on my understanding, QuickLook attempts to provide a preview of the alpha channel if the image contains one. However, some 3D software programs generate a black (empty, 0) alpha channel when rendering multi-layer EXRs. As a result, the image appears entirely transparent and only shows a black background in the preview.

Perhaps a hotkey could be added to disable the alpha channel when previewing.

Research direction

The issue does not name a file, test, or entry point. Start by locating the image-preview handling in QuickLook and reproduce the problem with a multi-layer EXR containing an empty alpha channel; done should include a way to preview the image without that alpha channel and verify the normal alpha preview still works.
