'I found Fotor to be simple and intuitive to use… I think many photographers will like Fotor Photo Editor.' – TUAW It has been optimized to work with Retina Display screens.Fotor was mentioned as the 'lite Photoshop' by BBC and it will cater all your photography needs. The app requires OS X 10.6 or later and a 64-bit processor. I don't know how long Fotor will be free, so grab it as soon as you can. The same developers have done some excellent iOS apps and it's nice to see those skills brought to the Mac. I think many photographers will like Fotor Photo Editor. With this version of Fotor, undoing a mistake is all or nothing. I'd like the app to go backwards step by step through all the changes and undo them one at a time. There is a button bewilderingly called 'none,' which takes all the filters and optimizations off. One thing I didn't like is there is no history-based undo. You can see your original image with a click, then reapply the filters. All the operations are on a panel to the right of the main screen. I found Fotor to be simple and intuitive to use. Text can easily be added to photos, and you can pop up a panel with your EXIF data. It also lets you import multiple images for HDR treatment.

The app even lets you apply tilt-shift filters to your images, and supports most image formats including the all important raw import.

The app also features 13 different one click enhancement options, as well as a large selection of effects and frames. The app has excellent editing tools, giving you control of the exposure, brightness, contrast, white balance, sharpening, blurring and much more. Best of all, it is free for a limited time. It's not Photoshop, but it has a lot of strengths.

Another good title to add to your list of photo editing apps is Fotor Photo Editor. There are still plenty other apps to choose from, including Pixelmator and Acorn. iPhoto is affordable, but its editing tools are rudimentary. Photo editing on a Mac presents a dilemma for budget-conscious consumers.
