Until a few years ago, I shot virtually no color. I don't want to process color film at home, and the labs, even the best ones, always disappointed me by doing low-quality work.
When I got my Canon 5DmkII in 2012, I began shooting color more, and over the last four years, my color work has improved greatly. I used to 'see' in black & white, and had a hard time seeing color as anything but simple reproduction of the scene. I now shoot a lot of stuff that I 'see' in color, and that I don't think would 'work' in black and white. I'm starting to like color photography!
Here are some examples:
This was shot in the last light of the day, a time that I think really is beautiful for color work. I don't think this shot in this light at this time of day would have worked in black and white. I could have gotten a great BW photo of this subject, but it would have been under different light.
The color in this is so subtle, it is almost colorless. It could have worked in BW, but I think having the color, soft and almost invisible, makes this image magical. This was shot on a very early foggy morning.
In this one, the color is a compositional element that defines the negative and positive space in the image. I could have done a fine BW photograph of this subject in this light, but it would not have had the visual impact that the color gives it.
This one simply HAD to be in color. The whimsical playfulness of the scene, a children's playground in a park with the smiley face in the sky, would not have been conveyed by a monochrome image.
