iPhone Photo Overlay App

October 13, 2011 9:52 PM

I'm looking for an iPhone app that can use a previous photo as a transparent overlay to match up when when taking a new photo. I want to take photos of a tree every week and have each photo look as similar as possible to show the growth of the leaves.

Hardly an app but, in case you can't find something like this:

If possible (probably not if it's in a public place), you could make a stand/frame of some sort to place your phone in when taking the photos, so that the phone is in exactly the same place each time. Leave the stand/frame in place between shots, of course. It could be as simple as a stake well seated in the ground with a couple of pieces of timber on top to align the phone identically each time.

Best answer: The app "everyday" does this but it's meant to be used for your face. I think you could use it for a tree though. The first time you use it, you drag a couple lines on that are meant to line up with your mouth, eyes,and nose. You could instead use those to line up the tree somehow. Each time you take a photo, you get the lines to help you line it up as well as an overlaid image of the last photograph.

Bonus points because it makes time-lapse videos really easily too!

Best answer: Check out Watch Me Change (WMC). It does it for free (with ads).

Response by poster: Ta JohnnyGunn. Paid version of WMC is only 99c. Also, it can have multiple "users" for different faces which I will use for different branches/angles.
