Thanks all for the comments.
Colin,
Yes, slide film has a narrower exposure latitude than print films:
slide 2 stops under, 1 stop over,
colour print about 5 stops total,
B&W print about 7stops total.
However, since I shoot essentially nothing but slide, on those occasions when I am compelled to shoot print stocks, despite the wider latitude, I don't feel comfortable the way I do with slide film.
As for the conversion to black and white, yes, after fooling about in Photoshop, I preferred the look of black and white for this particular shot.
By way of a contrast, see my photo "Home is where you make it" (in this same category about one page back) taken at the same spot, but left in colour.
