Hi

I need a way to transfer the alpha channel to a selection when loaded in Photoshop. I am saving a ifA16R16G16B16 formated multiimage to PSD-file. When i then open it in Photoshop, i can make a : Select -> Load selection  -> channel: transparency layer  -  to convert then alpha channel to selection.
But my image is still with transparency, and i dont know a way around that in photoshop, so i am wondering if there could be a way to save  PSD file with multiple layers (eventually 8bit) that then can be converted seperately to selections ?
