Disregard the orange photo in the corner, but basically I have the green photo and the blue photo as shown. I want to overlap the two images so that in the area where the two photos overlap, the blue photo is slightly transparent so you can see the green photo underneath. The only way I know how to do it is by making the entire photo transparent but then the white background starts peeking through. Help? I understand I could use knockout groups for this but I have no idea how that'd work.
Thanks in advance!
I would try the blend mode overlay. (But any blend mode is a kind of transparency!)
