I am using PSE8 and would like to show the difference in maps from a bygone age and today. I wish to superimpose an old map of 1831 over a modern type of map because there are so many differences in terms of roads (tracks etc. ?) and what we have today. As an example, this is a modern type of map in .jpg format although I would like to work with one that has no name places on it, I can put those on later : and I
would like to overlay that image with this, again in .jpg format. I can obviously re-size and crop as required but I think I need to use negatives etc, for the actual overlay which is presumably the tool that I need in PSE but I really am struggling. Can anyone point me in the right direction please ? TIA for any help given.
