The best photo app I’ve come across in awhile is Snapseed. It’s free (owned by Google) and offers a significant amount of control over image adjustments. It provides your basic crop, rotate, straighten features as well as a “Tune Image” section which gives you the ability to modify the brightness, ambiance, contrast, saturation, shadows and warmth. This is all you will need for most images.
The control adjustment for each of the tuning features, referred to as a slider, is as easy as a swipe of a finger; to the right for + and to the left for –. Very intuitive.
Snapseed also offers the fun features that have made apps such as Instagram so popular, but with more creative liberties available in post-editing: variance blur, vintage, black & white, grunge, tilt-shift (which is a modifiable edge blur and automatic vivid enhancement–my personal favorite) as well as a host of high quality frames & borders.
A “Compare” button lets you easily flip back and forth between the original and modified image throughout the post-production edits.
One of the best, and unique, features of the app is the “Selective Adjust” which allows you to tap your finger on a specific area in the image and adjust the brightness. This allows for finer tuning adjustments than almost all the other iPhone/iPad photo editing apps on the market.
The app is available for both iPhone and iPad and is a great addition to the IE practitioner’s app toolbox for any project requiring photo editing.
Available in the iTunes App Store
