Hi Everyone:

I am looking for an easy way to fade into one photo from another photo. In other words, from the middle "point", you can see both of the photos on top of each other to compare the changes. I am currently using Quartz to do this, but am running into a lot of trouble with that, so I am wondering
what
you all would suggest. I would be happy to send over my current project if
you would like - it's based off of Scott Stevenson's tutorial here:

Thanks for any help.
