This is my recent study in Blender composite nodes although I've done this many times but this time focusing on achieving desired compositing technique from Pixl'r O'Matic android application on my phone.
I include the image sample from the app so you can compare it from the real app.
It's not 100% same from the application but it is currently what I achieved.
You can click the Viewer node to view each of the Node Groups.
More to come... just visit my blog
http://siraniks.blogspot.com for updates.
Currently some nodes are not compatible with some images and will show some artifacts.
You can use it freely for commercial/non-commercial but just give me a credit back.
And don't forget to drop me a comment from my blog.
