I have to make a decision: shoot 4x5 color film (positive or negative), send it out for processing, scan and convert to B&W -OR- shoot B&W film, develop myself and scan. I'm presently doing the former. I do like the adjustments I can make to the scans with Lightroom.

Is there a clear quality advantage to the latter? The only advantage I can see is that B&W film is cheaper than color.
