...its not an easy choice for me though.
But it's a choice you, as an artist, have to make, not someone else. That's just my opinion, of course, but I believe it is one of the few things the photographer can't ask for critique on (I accept that many feel they can recommend though). I realize that many members here have asked for help deciding, some far better at this craft than I, but it seems to be one of the basic decisions a photographer must make at or near the beginning of the artistic process.
Most of my own B&W decisions are made when I look at the scene before I bring the camera up to my eye. Sometimes I see it when I am doing my initial sort, after importing the images from my camera. And although I do a lot of the processing of the picture in color, I fully intend from the start to make this a B&W image. I may even find another picture I made from the same scene or series should be a color image.
When I offer a photo up for critique, I am hoping other photographers will give their opinion on format, composition, cropping and most of the processing options. I expect to be critiqued on focus, angle, f-stop and other basic camera settings. But seeing a color or B&W scene or subject is my choice and one that is made very early on. To me, asking whether a picture should be in color or B&W is almost like asking if I should take the picture at all.
Every photographer should have, at least, the self-confidence to make a picture and to know whether the picture in their mind is color, partly color or shades of black and white. And then ask for help in making it the best color or b&w it can be.
Sorry for the diatribe. I've been wanting to express that opinion for a while now. I know others may not agree, but I think we all have to decide where our artistic expression begins and at what point we can ask others to help develop that expression. When I look at your photography, I see artistry at work. It takes me aback, though, when you say you can't make one of the very first decisions an artist has to make. I have confidence in you. Why don't you?
Best R'gards,
