Thanks for the reply Gavin.
I tried the custom WB method at the weekend and frankly got some pretty strange results. I think I ended up with a 2000K difference between the CWB and the cameras own AWB. The CWB ended up being much too warm. I really haven't worked out what I did wrong, but I think it was probably down to the muppit holding the camera
. The shots I've posted over the in the sports section were corrected to the cameras AWB setting and were much more accurate. I think I'll stick with AWB and maybe shoot a grey card as a reference in between races - if nothing else it'll help me sort the pics when I get back home!Thanks again.
Simon.
The answer might be a colour temperature meter. Time to reach for the cheque book again
