Perceptual and Real Colour

I just wanted to say a big thank you to DOP who pointed out an excellent post by Howard Grill. The post, which is titled "What is Real?" talks about the way we perceive colour. Howard discusses an onsite workshop given by Alain Briot and Uwe and Bettina Steinmueller at Antelope Canyon. I won't go into any more detail, it's worth a read.
