Apple migrant: Pls recommend photo edit app?

view story

http://androidforums.com – I’m a tech guy but an Android newbie so please bear with me J I’m looking for an advanced and solid Android photo editor that allows for selective (masks, layers, etc.) picture changes , something similar to my favorite iOS apps like Snapseed, iPhoto, Photogene, etc. I’m not really interested in a sheer number of silly pseudo Instagram effects but more into core photo edit functions and filters that can be applied selectively to the areas of pictures –curves, exposure, sharpness, saturation, tone control, gradients, noise reduction, etc. Will appreciate suggestions. Thanks. (General)
