This question is directed at those who have used both Canon and Nikon
DSLR. Do you notice any difference in color rendition between the two
cameras?

Do you notice any difference in image quality (11x14 and 13x19
enlargements) when using equalavent lenses?

Do you have any preferences and what are they and why?

Yes there is a difference in color rendition. If you have 2 people
shooting the same event, such as a wedding, you want matching models if
possible, but at least matching brands, so the pics are consistant.
Otherwise it will be noticable that 2 cameras were used.
