The disadvantage of using a Nova Processor for B&W printing is that in a dish when processing B&W, especially fibre based, I can do a little bit of local work on the image such as painting certain areas with neat developer using a 1/2" brush to bring out highlights or deepen the shadows. Also applying a bit of extra agitation by rubbing the required areas areas with my fingers to do the same.

It is also possible to give a plain water bath treatment in a separate dish to reduce the depth of tone in the paper by up to one or two steps in the shadow areas, a practice that cannot be done in a deep tank.

Using the NOVA for stop bath and fixing doesn't affect this specialised development process though.
