We spend a lot of time doing various image finishing processes in Photoshop but rarely go into the incredible depth it offers on other levels.  This was a learning experience/experiment for us...

Earlier this summer we had the chance to visit Siesta Key beach and catch nearly identical images from two different unsuspecting beachgoers - young and elder.  Using the magic of Photoshop we were able to combine the two into a little animation.  (animated GIF)

To do this all it takes are a few simple steps - 

•  Gather the images you want to animate into one folder.

•  Click File > Scripts > Load Files into Stack. When the “Load Layers” window pops up, click Browse to select & open your image files, and then click OK. This should import the files you selected as individual layers in your document. Rearrange the layers into the correct order, if necessary.

•  For Photoshop CS5: Open the Animation palette (Window > Animation) - in CS6 or CC: Open the Timeline palette (Window > Timeline )

Adjust the order and durations in the Timeline window - then - Click File > Save for Web & Devices, make sure the file format is set to GIF - Done!

It's fun to play with - give it a try!
