Hello all,
A test series with a Leica Macro-Elmarit 100/4 on the 20D, Winter Jasmin at 80cm
f11, cloudy/overcast at mid-day. There may be some slight variations in
brightness due to thickness of cloud cover, but I think these are negligible.
Shot in CR2 RAW format 600dpi. Mid high contrast, +1 stop exposure compensation
for the off white background applied in EOS viewer utility and saved / converted
to TIFF , Photoshop elements 3.0 was used for auto contrast and unsharp mask
with settings 6.0,5.0,0, cropped and converted to jpegs at 96dpi after processing
Starting with a full frame shot at 100 ASA equivalent
