This is from a 1.36 megabyte, Medium-sized, Fine compression jpeg done in Monochrome mode, Sepia Toning, Yellow filter effect,made with the 20D in RAW+JPEG mode at ISO 800. The original capture was 2544x1696 pixels,for a 35.333 inch by 23.556 inch print size. I made this 704x pixel web reduction from the in-cam JPEG,not from the RAW file. This is how the 100mm EF MAcro looks wide-open from close range, hand-held. I kind of like this lens as a people lens, for small subject areas.
