About the amazing x100 color
Midwest, I have hundreds if not thousands of photos of my son in color, and yes his coloring is awesome. My children are two of my favorite subjects. But I also think color can sometimes be distracting, where with certain color shots you can get lost in looking at the colors versus the actual subject. This is purely a subjective and personal taste opinion of course.
And I prefer capturing in color and converting to monochrome versus shooting in black and white. That way I always have a choice. In fact often times I process in both and then decide which one I feel is more compelling and go with that.
