There is also a set of firmware modifications for Canons made by a company called 'Magic Lantern', and it's possible that these include color swapping.

It's not available at least in my Nikon, or any as far as I know. In this option, you select one specific color and the color it is to be replaced with. Some point and shoot cameras also include an option called 'color swap', which looks just like what you are looking for, but I don't think it exists on DSLR's, at least currently. It's a gimmick that can be fun to try, but hard to work well without becoming a cliche. If you ever saw the movie 'Schindler's List', this is the effect used in which, although the film is entirely in black and white, there are some scenes in which a girl's red coat is conspicuously colored. In this option, you choose one color that will be highlighted, and all others will be rendered as black and white. Our vision is very good at editing out clutter and ignoring things that are in the field, and when we take a picture, we often need to remove in the image much of what our brains remove from our sight without our even realizing it, and to provide organization of what is there, that we don't realize our brains are doing.īy the way, I do read that Canon (unlike Nikon) does offer what it calls 'color accent' in shooting, which Nikon offers only in post. My main advice at this point would be to concentrate on training your eye and your sense of composition to capture what you really want to see, and for this the main thing is to practice a lot and learn how the two dimensional image you get from a camera differs from what your much more versatile eye sees.

I hope I can continue with at least some advice here, but I hesitate to interfere with someone else's ideas on how to go about things. I'm not sure how much I can contribute that is Canon specific, and at the moment, I am pretty busy and away from home with family matters brewing for a while.
