Juxtaposer
the revolutionary photo compositing app
for the iPhone / iPod Touch
 
First, load in any two pictures - perhaps one of your dad, and one of your dog.
Next, use your finger to erase around your dog's head.
Quickly zoom in and out or move around using two finger pinching gestures.
To cut out your dog's head exactly, first zoom out and make a rough outline, then zoom in, and erase or un-erase with pixel-accuracy.
Switch to move mode and use two fingers to move, re-size and rotate your dog's head into place over dad's.
It's easy, intuitive and fun, and you'll have a great new Dog-Dad in about a minute.
 
There is detailed in-program help if you need it, and many cool features, including:
  1. Unlimited undo means no mistake or accidental brushstroke is permanent.
  2. Use hard or soft brushes to create sharp or blurred edges.
  3. Create smooth blends between images with transparent brushes.
  4. Keep adding elements from other pictures to your composite image if you like.
  5. Red mask mode (see image below) lets you accurately isolate part of one image without being distracted by the second image in the background.
  6. Translucent mode makes it easy to align your images precisely.
  7. Switch to and from full-screen with the tap of a finger.
  8. Double-tap to switch between erase and un-erase functions.
  9. The stamp tool lets you add multiple copies of your cut-out to your composite.
  10. Work in portrait or landscape orientation; optionally have images auto-rotate.
  11. Set advanced settings in the Settings application.
  12. Save directly to your photo album.
Juxtaposer lets you combine any pictures - from your camera, saved photos or any other images - quickly and easily.
 
Take any element from one picture and add it to another. Put your friend's head on a statue's body, remix your pets into a mythical creature, or magically join your favourite band, it's simple and the process is fun.
