I just got round to looking at these. I was a little puzzled, at first, because Shel doesn't *have* a JPEG picture of me. What he has is a TIFF, made from a RAW file. Those aren't JPEG artifacts (not surprising; no JPEG software was involved). That's sensor noise, because we were shooting at 1600ASA with noise-reduction turned off (even then it's a 1/6 second exposure. Shel has steady hands).
