Greetings!

Can anyone help me with what I believe to be a simple problem?  I want to stitch three frames side by side to one another, and then have them frame a single photo.  So, in essence, there are three tiles that each contain one third of the single image. 

I'm thinking there must be a way to do this either in my existing software: Lightroom, Aperture... or ... If there is an app out there to download.

Help!   

pretty simple, I've always done to in PS though, but this should show you

oh, and if you haven't shot it already, be sure to leave at least a 25% overlap of frames

Thanks so much Moto.... but this is kind of the opposite of what I want to do.


I have a SINGLE image -  I want the end result to be that single image with three frames over it.

If I read your description correctly, I think you want to create a Single Image Triptych. Is this what you are looking to do ? https://www.youtube.com/watch?v=HQmp5CkPkG8

Procedure sounds like   

rectangular select  / edit - cut  / file - new / edit - paste  / save as (new name)   
     (pick a third)

                                      and repeat 2 more times


3 new files when placed side by side will show the full image
