I wrote to Artie this morning and received permission to use his photos here on the forum...

Artie's words:

"On the Friday Anhinga Trail ITF-Workshop we were fortunate to watch an alligator dine on an unfortunate Brown Pelican. With the Mark III in my hand I figured that it would be a good chance to check out the high ISO settings; with the gator chewing I knew that I needed a shutter speed of at least 1/500 sec. to freeze the action so ISO 3200 it was. I think that I had set the Custom Function for High ISO Noise Reduction and the image was processed in DPP with Low Noise Reduction set for both color and luminance. The converted RAW image exhibited very little noise. Both Robert O’Toole and I agreed that the noise in this and other ISO 3200 images from the Mark III was comparable to ISO 400 in the 1Ds MII and the MII 1DN. Virtually noise-free images at ISO 3200 will open up new worlds to nature photographers."

The first photograph was with the Mark III, Canon 100-400mm IS L Zoom lens handheld at 210mm with the EOS-1D Mark III. ISO 3200. Evaluative Metering -2/3 stop: 1/500 sec. at f/5.

"As it got darker and the gator’s thrashing became more violent so I went for the whole nine yards: ISO 6400. The large J-PEG (representative of the RAW file when viewed in Breezebrowser) exhibited lots of noise—especially in the red channel, so I converted the image in DPP with High Noise Reduction set for both color and luminance."

The second photograph was taken with the Mark III, Canon 100-400mm IS L Zoom lens handheld at 190 mm with EOS-1D Mark III. ISO 6400. Evaluative Metering -2/3 stop: 1/1000 sec. at f/5.
