PHOTOLUX RENDERING - ALPHA CHANNEL ISSUES
PhotoLux rendering is much better than ProPhotorender, but the alpha channel export feature doesn't work.
In ProPhotorender, selecting "Render alpha" exports a channel mask that software such as Photoshop can use to isolate the product from the background. This is great for tweaking the image only, or quickly putting it on a different background.
The same selection in PhotoLux creates a mask of the entire image. Fairly useless, as this can be done with a single rectangular selection.
