Fun app with many uses
This is one of my most used apps - so I must endorse it. I like the ease to experiment and redo with the various settings - esp. blend width. Superimposing one photo over an other using full blend width can create an intriguing effect. And gradually blending a bunch of photos in a row or column is great for creating a static morph effect with time elapse photography. Ive made great large canvases with it.
