    Usually when you create an alpha channel, it consists of an object which you are trying to separate from the background. Therefore it is useful to use a high contrast setup where the object is light coloured and the BG is dark or vice versa. Is your FG very complex and does the BG shange, if it is you might be able to mask around it, but that would take forever.
