I have often made the claim that I don't "need" a yellow filter with TMY-2. Yes it is slight. If clouds are important, you would still want to use filters. But you can get away without it.
Here is an example photograph that led me to that conclusion. No filter. 1/300 f/16 The day I took the picture, I didn't even notice clouds in the sky. I expected blank white, and made no adjustments when printing. Galerie 2.
