Thanks, I spoke to the "award winner" and his attitude was he subcontracted it and was sorry it has happened, but take it up with Photog B. Pretty much washed his hands of it.
I have sent a rather long winded email to Photog B, I've given some harsh but fair and polite advice (some taken from those on POTN who have been kind enough to review) and given him the options of either editing the images WITH ME in my office to a mutually agreed standard or that he sends either original RAW files or uncompressed TIFF files and I edit them myself and say no more of the matter.
On the plus side I have managed to get some of the low resolution files looking ok so it CAN be done with these files, it would just be nice to have some more than a compressed JPEG to work with.
We'll see what happens, but thanks to all who have looked at the images.
