Paterson 12x16" Tray (White)

I'll answer this the best I can: In most cases, I use between 2,000 and 2,500 ml or a little over half a gallon to adequately submerge the print. This is when I plan to develop multiple prints. However, at times, if I only develop 1 or 2 prints, I leave the tank empty and simply pour enough solution over the print to complete the developing process which also works well and you can simply pour the solution back in the container once finished. Hope this helps. m
