Darkroom keeps iOS photo editing simple (pictures)

This new photo editor sets itself apart from the rest with cool new ways to adjust your photos, but it's still missing some important features.

Darkroom's cropping tools let you select from several standard aspect ratios, but you also can drag the corners by hand.  It also lets you level the image.

Use sliders to adjust saturation, temperature, sharpness and more.

You get a handful of photo filters with both retro color and black and white options, or you can create your own.

To get Curves, you'll need to pay $2.99 through in app purchase. But $2.99 is a good price for an app with all these features.

Adjust curves by swiping in each of the different columns. You also can single out reds, blues and greens over on the left.
