I want to stack x number of photos to incrase the exposure of the final image. But I need to do it manually, I mean, using Photoshop but without using wizards.
My approach would be using a layer for each photo and aplying an alpha for each layer. I want every photo has the same weight in the final image, so it must be the same alpha.
My question is this: If I apply eg. 50% opacity to each one, every photo will have the same weight, but I'll can see the empty background because every one are semi-transparent. To avoid this, should I have a photo with 100% opacity? If so, that photo will have more weight on the final image, something I don't want...
Do you get my point? Any idea?
Thanks in advance!
