I am very new at photoshop and I am not sure if I have chosen the correct title for the question but I'll give you an example so hopefully that will do it. So basically I am trying to blend one image into another and I've used mask and everything to cut edges but it still doesn't look very authentic and I would like to know if there is a way to paint the image in colours similar to those of the background so that it blends easily. This is what I have for the moment:
I would like for the image on top to be brownish like the old paper on the background instead of gray. Is that possible? Thanks in advance!
