How to Merge Two Images in iPhone

Apple iPhone, a faithful girl friend it is, will follow you anywhere you go.  So suppose you have taken two snaps and an idea comes into your mind that you will merge them both so that it makes a terrific combo of the best of the two. Again, suppose you are lying to your spouse that you are in Moscow when you are in LA. Don’t think much. Take a pic of yours and download any pic from Moscow and merge them as if you are shivering in the cold there. Wicked I know. Okay, enough of evil planning, let me tell you how you can do it.

What you need is an iPhone app,  Juxtaposer from Hendrik Kueck,

Juxtaposer features:

• Unlimited undo means no mistake or accidental brushstroke is permanent.
• Save directly to your photo album.
• Save multiple sessions and return to them later.
• Save top image cutouts as ’stamps’ and use them in future projects.
• Use hard or soft brushes to create sharp or blurred edges.
• Create smooth blends between images with transparent brushes.
• Keep adding elements from other pictures to your composite image if you like.
• Red mask mode (second screen shot) 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.
• Switch to and from full-screen with the tap of a finger.
• Double-tap to quickly switch between erase and un-erase functions.
• Flip the top image.
• Set advanced settings in the Settings application.
