I always assume that wherever 2 or 3 are gathered together, one of them will have a better camera than me and lifelong ambition to be MC...but

50 people assembled for a family get together, the threatened heavy thundery shower arrives both precluding going outside and ******ing up light inside from reasonable-without-flash to practically dark.

49 all form up and suddenly only muggins left out front, wondering how to turn the flash back on (hate it and rarely use), not even a tripod, and a unison call, "set it up and then join the rest of us"

Well the camera does what it can, balanced on a chair and inverted saucer, and I have 50 smiling faces, the ones in the centre not at all bad, but, near the periphery, ghastly noise ie red faces with green shadows.

I know I should have (a) had decent lighting & tripod (b) an appropriate camera, or (c) refused on grounds of impossibility, but can one or two of you either (1) say 'there, there, we all get caught out sometimes (2) suggest an order for emergency salvage, ie which order to correct lighting (overall and centre to periphery), reduce noise and re-sharpen, correct white balance and/or skin tone?
