For me, no more than four exposures 'cause thats all I've got (two film holders!)

I have four 7x17 holders. If I am out for the day, I have to carry a changing tent.

I rarely make two exposures of a subject. This morning I went down to the lake for an hour an used four sheets of film, each at a slightly different location. If I had carried all the holders, I would have used them.

12X20 at 1200 dpi grayscale and resulting file is 660mb.
7X17 at 1600 dpi grayscale and resulting file is 580mb.

If cost analysis were the only consideration you would be right in that making a duplicate exposure might be a better solution. But most films available for ULF (TMY excluded) do not provide enough contrast for the processes I print with, regardless of developer and length of development time. So my choice is either scan and make digital negatives, or make enlarged negatives on high contrast lith film. Both methods are capable of equally good results, but I prefer the former as a more productive work flow.

This posting surprises and disappoints me somewhat. I take it to mean that one can not get ample contrast for such processes as VDB and palladium with Pyrocat HD.

I hope I have misread the posting. I just finished developing some Efke 100 in Pyrocat and they are not quite as contrasty visually as I would hope so I was thinking of trying other dilutions to accomplish my goal. I have a color densitometer, but not a UV one.
