Not much I did enhance the darks a tad and the contrast a tad. it's basically right out of the camera as jpeg. The bounce flash helped with the front of every body and it was a real dark ceiling where I bounced it from so I think it didn't get a whole lot of light. I used the EL-5 flash on manual at quarter power I think and I think Iso 5000. I got real lucky with this shot and I'm glad you like it like I do.
