Flash! Aha!

I bought a flash today for the PEN, for the impending wedding shoot. I have a shitty flash that just plain flashes when you take a picture with a paltry GN of 20. My new flash is automatic with TTL metering and a GN of 36. It is also taking some getting used to. I had thought that I would arrange 16 pictures I had taken with slightly varying setting of essentially the same thing into a grid of thumbnails, but when I ran them through Photoshop's collage script I got this. It's not the collage I wanted but now I understand what the collage script does and I don't have to spend the time relentlessly copying, pasting and resizing layers to get the effect I was expecting.
