During this RAW converters test, an interesting fact was discovered: Nikon is stealing from us valuable pixels produced by CCD. In every RAW file there are actually 6,122,560 pixels, instead of 6,016,000 they're telling us! Some of tested converters are reading and presenting some or all of those hidden 106,560 pixels. It's not much, but makes one happy :) 6.2 instead of 6.1 MP for free!
I have taken my market pic http://www.pbase.com/miljenko/image/37400285/large and simulated how much is shown (or hidden) by every converter. All the pics were aligned to the lower left corner, so this is what you'll loose with each of converters at the upper right corner. Of course, cropping occurs simetrical, equal on all sides by half of what is drawn, EXCEPT for C1 that crops just like shown, in the upper right corner!!!
