This image is from 2012, during the snowy owl mass migration to Ocean shores, WA. It was taken with the 1D4 and the original 500 f/4 IS. I went back and processed this one with the latest DPP. At the time I had a 27" monitor and my standard output size was only 1600 pixels. Now I usually save at 3000 pixels to get a descent size on my 4K NEC. The 1D4 is history but with the latest DPP and the Neat Image I got a pretty good quality file. Here is the web presentation, hope you like it
