PhotoCurves is one of the most powerful and flexible image editing tool available on the iPhone, essentially enabling you to create your own filters. Since photographers effectively paint with light, curves is central to their practice because it affects light's two primary influences: tones and contrast.

Open an image in PhotoCurves, tap a point on the curve itself, and drag it to the desired position. This will bend the curve. Bending the curve will take input tones and selectively stretch or compress them. A tonal curve is controlled using any number of anchor points. A diagonal line through the center will therefore leave tones unchanged. To remove a control point, click and drag it off the graph.

The curves/effects can be layered to produce even more dynamic results. You can also zoom in and out (pinching motion), as well as pan (swiping motion).

PhotoCurves Free supports only the RGB color space. PhotoForge and PhotoCurves Full, support editing in RGB, CMYK and CIELAB color spaces.


• Edit RGB color space with the curves editor.

• Unlimited undo and redo option allows you to revert your editing mistakes.

• Save to 4 different output sizes; 640x480, 800x600, 1024x768, 1600x1200 (Change through settings menu)

• Pinch and swipe screen at any time to zoom and pan.

• Resume previous sessions if interrupted.

• Load photos from your camera and your photo albums

• Edit in portrait or landscape mode

• Hide the toolbars in full screen mode

For even more features and control check out PhotoForge also available on the app store.

Advertising App

This is essentially an app that showcases just one feature in PhotoForge.
Its a great feature, and one of the main reasons I bought PhotoForge...
But PhotoForge does this and about a dozen other things, like everything PhotoSharpFree can do, and then some.

If you like this, you won't be disappointed by PhotoForge.

5/5 stars

Almost perfect

You can easily emulate lomo photos by utilizing "S" curves with the Red, Green and backward "S" w/ the Blue. It would be nice if it saved in full resolution for the 3GD. The paid version of this app doesn't and neither does Photoforge app. They save at 1.9MP. If they added a vignetting feature and full-res for saving, this app would be virtually perfect! One of the best apps out there.
