I shoot outdoorsy shots a lot, probably eighty percent. Most are in the local hills, which are green as green gets in the winter and spring, and light straw in the summer. The oak trees are always dark green. So if I shoot bw at green hills, everything is dark, not much contrast, and I kindly don't care what you say, a beautiful, rich, bursting-with-moisture emerald green hill is not best shown in bw.
On the other hand, the dry summer hills are improved by bw. The tall dry grasses are light, but the spaces between them are shadowed, and in color, you get this light straw-and-black shadow look, and it Don't Look Great. Shoot it in bw, and it becomes different shades of grey, much nicer.
I often shoot color and convert to bw in PS elements with one click, and it may be cheatin', but if often saves a lousy photograph.
I get color developed and scanned at Target. I'm going to learn bw myself this fall. That may shift me more to bw. But anyway, I like to overuse both!
