Autodesk Pixlr is a simple image editor with one or two unusual extras.
The interface is easy to understand. Click Open, choose an image, it appears in the work area and you choose the functions you need from a toolbar. You don't even have to figure out tiny icons, because the buttons have text captions as well.
There are the usual basics: Crop, Resize, Colour/ Contrast/ Brightness adjustment, Blur, Sharpen, Smooth, Text captions.
Each of these is kept as simple as possible. You don't get to choose your resize algorithm or correct brightness with curves or histograms: it's just entering figures or dragging sliders.
Fortunately, there are a few more advanced tools. Rotate isn't just 90 degrees left, or right; instead you click and drag a slider to rotate your image by fractions of a degree, while an overlaid grid helps you line it up correctly.
A Heal tool provides various ways to remove skin blemishes, clean up old photos and more: just click, the defect disappears and is replaced by pixels matching the surrounding area. (As usual, this is great sometimes, useless at others, but it's still a plus for a starter photo editor.)
A Focal tool allows you to highlight an area in your image, boost its colours and apply a blur to everything else.
A neat Splash effect selectively replaces specific colour ranges in your image.
Bonus extras include an unusual Double Exposure effect, while Auto Contrast and Autofix tools try to solve all your image problems with a click.
There are also a bunch of stickers, overlays, borders and extra effects. None of these are particularly special or surprising, and they aren't available initially, but if you sign in with the Pixlr account you created to download the program then they should be unlocked.
Most of Pixlr's editing features are very basic, but it's very easy to use, and the scattering of more advanced extras helps it stand out from the competition.
