Layering photos in Lightroom can be done rather easily!
I set out this week to find a way to make memory mates, or picture packages with layered images for event photography I've been doing lately. I know I can easily do it in Photoshop with an action or script but I didn't want to spend the time to make that action then tweak it. I only had about 20 of these to make, so doing it in Lightroom would be ideal. I found an easy way which works well, then I print them out using my Epson 7800 24" printer. Any questions ask away! Keep shooting!
