Some people can't believe that quality of the colour in your print. Is it a manipulated thing?
I don't quite know what you mean by manipulated. I spoke before about the control that you have and about interpretation. Now, interpretation in colour photography means that, in making the final print, you can accentuate - increase the contrast - if you want. You can make it more brilliant, or less brilliant. It's the same in black and white. But the colours are there. People say: "Oh, that's not true colour; that's not really there; there's nothing like that; I never saw anything like that." All I can say is that they're not looking. They don't see.
