From PicMix Media:
The app to easily mix two (or more) pictures into one montage. The pictures can be freely moved and resized and you have complete freedom over which parts of the photos you want to keep. You can remove or re-add parts of the pictures with a simple, adjustable brush that makes it easy to mask out parts of the layers. With this technique you can create collages, replace backgrounds or superimpose layers of photos any possible way you can imagine. You can also overlay semi-transparent layers of photos. Multi-layer support to manipulate multiple layers separately- Easy to use photo juxtaposer tools- Color-sensitive brush follows the edges automatically when cutting out shapes. Blending options to superimpose the layers to a collage even more creatively (perfect to blend photos into a multi-exposure picture) - Stored cutouts can be reused for different montages. Export layers as PNG files with alpha channels. All editing steps carried out in full resolution.
