Asher, you have made some very interesting points. Thank you. Above all, you have taught me that it certainly is a fine idea to return to the same subject matter over a period of time -- kind of like Degas and his ballerinas, now that I think of it! This should help me, too, in my pursuit of each subject's "essence" as Minor White talks about.
That being said, unfortunately I will have to wait until next spring to do this for 2 reasons. First, the run off is non existent at the present time in the dry weather we've having. Second, my mobility is severely restricted as I fell off my bicycle at the beginning of June and am still healing a fractured pelvis! The doc and the physical therapist say it will take 6-12 months to return to normal. That should be just in time, too.
I find your suggestion of trying these kinds of shots in B/W film very intriguing. I'll try my hand at this digitally for the present. In itself, that will be a whole new learning curve.
