Under identical circumstances, yes. I'd do it again. I couldn't say no to somebody close to me if there were absolutely no other option. I made it very clear. I would do my best, probably get a few shots, but promised them zero. Discuss the potential pitfalls. You could goof one setting and all the photos could be trash. Could it possibly affect your friendship? At the wedding I shot, the couple wanted a specific shot. light paint a heart with sparklers, then pose inside the heart for a kiss and pop a flash. I completely failed on that shot. Another nightmare that nearly ruined all my shots: I never change my capture settings on my camera. It's always raw+normal quality jpeg. When I imported the files from that wedding, I had no raw files! Only basic jpegs! Somehow the capture setting changed. It was terrible and I lost a lot of shots that were underexposed that could have been saved with raw files. The keepers were of barely printable quality and should have looked so much better! There's so much that can go wrong. So much unpredictable. And such an important moment and no do-overs!
