MaxCurve 3.1 for iOS

MaxCurve is all about adjusting curves for photo editing, and it comes packed with 20 different curves neatly organized into sets. You don’t have to use every one of them. The RGB set is for messing with individual color channels, while the Lightness set helps with contrast, exposure, gamma, and temperature, plus it has a black-and-white curve. Then there’s the HSL set for adjusting hue and saturation, and the Lab set that separates colors into warm and cool tones.

It works with JPG, TIFF, and PNG files up to 4096×4096 pixels, has a live-updating histogram, and lets you create your own presets. You can also find everyday editing tools like cropping, rotating, flipping, sharpening, adding grain, and vignetting, along with a zoom feature for those detailed edits. Plus, you can connect to Photoshop over Wi-Fi to import images from the desktop version for editing on your iPhone. All in all, MaxCurve gives you a serious level of control that can even rival some desktop applications.
