Ah ha, Tim Rudman.
I've heard a romour that Santa has reserved one of the last copies of the current print run of his photographers master printing guide.
Been looking for this book for a while.
I wasn't keen on HCA as it's another big tub of solution, another step and another tray. My darkroom is tiny, only the Nova 12x16inch fiber processor I recently purchased makes a big print possible. Print washing is in the bath in the bathroom.
Most people seem to stress the importance of HCA, and I guess it should save time overall plus make me feel more confident about the washing.
So there will now be two 12x16 trays in the bath.
I take it one tray half full of HCA will clear a number of prints.

Meanwhile I hope santa really has got that bloomin book for me.
