In Photoshop I have a layer A which is placed onto another layer B using a multiple blend. The result looks good.
Now, I wish to hide layer B so that layer A can be saved out as a semi-transparent PNG and used on a web page which has B as a background. The alignment may not be perfect, so I don't wish to include the background in this PNG.
The problem, of course, is that as soon as I hide B layer A returns to it's original colours since there's no longer anything to multiply with. What I need is a way of fixing the result of the blend - the colour shifts that A was subjected to - such that I can remove B.
Does anyone have an idea?
