Well for print use, editors want the image to be 300 pixels per side. So for let's say, a 5x7 size in a magazine the math is:
This is the same as 3.15 megapixels. Remember that if you crop the original image in your computer to make the elk bigger in the final scene or to make the composition better, you lose quite a few pixels.
And yes, I also always shoot in RAW/JPG combo. The JPG's are faster to load in my image browsing software than the RAW. The RAW are much higher in quality, so that's the one that I edit for use. I could never have pulled all the detailed color out of the sky from the JPG version in this shot
