Just sharing this app. I always use it in enhancing photos taken with my iPhone and it gives pretty nice results. Just a quick look at its features. I also added a before and after sample at the end.
The app is photoforge (NOTE: i dont make apps. just sharing this neat photo editing app)
This is the sample photo
Some basic editing tools
It's got a popcam, yay!
You can choose from a set of film effects
Add vignette by choosing from different lenses
It has lens filters as well
And flash effects
And some editing features for details
And for curves
Sharpening and unsharp masks
Here's the "before" photo
After. (Am not really an expert at this but I love how the colors turned out) 😊😊😊
