As this has become the thread for all things technical on the photography front with some good advice being given, I am going to mention that I have been unhappy using AWB for some time. The thing is, it (AWB) is one less thing to be concerned about so is convenient, but for the convenience I find you have to put up with being less than happy about the result... I tried setting CWB using available white backgrounds wherever I am going to take a few shots, but I guess I got impatient with getting that right. I am now playing around with everyone's mate Kelvin, but am finding him a bit confusing. There seems to be a lot of stuff about this written in internet land, and a lot of people struggling with it, but apparently there is no easy fix and not much simple / fast advice... I guess there is nothing for it but to go with the old adage "practice makes perfect", and soldier on until a fair level of understanding is reached.
