Additional points on sharpening:
1 - the 10d default settings reportedly result in less sharpening than the D60 (hope to be able to confirm this later this week)
2 - if you want sharp out of the camera, you can alter the sharpening parameters on DSLRs - but reduce your post processing options
3 - I've had publishers request an unsharpened version as they are familiar with DSLR output and have sharpening methods tuned to their production requirements ... as more publishers become experienced with dslr output, I would expect this to become the norm.
Anyway, these samples look very promising indeed, in particular, the colours look very true, and UA
aircraft can be a pain to get right.
