Juxtaposer: Fun with photos on iPhone / iPod touch

Fans of Adobe Photoshop rejoice! Have you been waiting for a way to whip out your iPhone or iPod touch and be able to juxtapose Arnold Schwarzenegger's head onto Pamela Anderson's body? Your wait is over -- Juxtaposer (click opens iTunes) is now available in the App Store.

This $2.99 app is a lot of fun, as well as one of the best-executed compositing tools for a mobile device that I've ever seen. Features include:

• Unlimited undo, so no mistake or accidental brushstroke is permanent.

• Hard or soft brushes to create sharp or blurred edges.

• Smooth blends between images with transparent brushes.

• Red mask mode lets you accurately isolate part of one image without being distracted by the second image in the background.

• Translucent mode makes it easy to align your images precisely.

• The stamp tool lets you add multiple copies of your cut-out to your composite.

• Work in portrait or landscape orientation; optionally have images auto-rotate.
