Photo Shine (Photo Editor)

Just like you’d expect, this free photo shine app comes with a range of preset filters. However, unlike most apps, you can edit these filters and even create your own from scratch.

It also has all of the classic tools, such as cropping, straightening, frames, text, vignettes, etc. And the sharpening feature does the job without making the image look grainy.

Then, things get interesting.

Snapseed has precision masking, which allows you to edit the depth of field – photographers often do this to make the background blurry and bring the foreground even more into focus.
