Almost all mobile editors that I’ve seen just allow you put filters/text/etc over them.
I’m looking for an app that will let you have multiple layers, bring in a second image, cut out the background, resize and move it, etc.
Are there any apps like this?
I was astounded by snapseed. Depending on what you want to do you might find it quite capable. It has a raw processing engine that works even with new DNG formats and offers a wide variety of color grading options.
Have not tried any image overlay stuff though
