Mighty Deals have an interesting deal for non-pro photography enthusiasts like me, The Mac Photo Bundle. There are three apps: Snapheal, FX Studio Pro, and ColorStrokes. My favorite and the one that make the deal worth it is FX Studio Pro.<!-- more -->
It's basically Camera+ for Mac. Lots of filters and frames to choose from. Easy navigation. Switching to another filter is easy, fast, and smooth, at least in my 11-inch, Mid 2012 Macbook Air.
Second one for my favorite is ColorStrokes. From the website:
With ColorStrokes you have the entire color palette in your hands. You can recolor the image and even bring colors to the black and white shots, thus letting your photo creativity truly blossom.
And the last is Snapheal. To be honest, I'm not satisfied with this one. It didn't work as expected and advertised. It depends on the photo and the object you will try to remove. Works better on small objects. Though the developers included interesting UX to prevent you from getting bored while waiting for the processing to finish.
FX Studio Pro is $39.99 (3,450JPY) in the Mac App Store. ColorStrokes is $4 in the Mac App Store, though it's 30% OFF for a limited time now. Snapheal is $19.99 in the Mac App Store. All three in this bundle will set you back $20 (1,600JPY) only. Grab it while it lasts.
