Me too. In fact, I’d rather have the range of control afforded by grayscaling a captured color image, even over one those oh-so-expensive monochrome cameras. I even keep my grayscaled images “three-channeled”, that is, in the RGB encoding (R=G=B, for monochrome), so I can add tone back into the image (bit-o-blue for cold metal, bit-o-red for vintage sepia, etc…)
Not the same experience as mixing potions and dancing with paddles and masks in the darkroom, but still quite satisfying…
