Ilford Ilfosol-3 Film Developer for Black and White Film (500ml)

Well, 1 part developer and 4 parts water makes a stronger solution, so all other things equal, it would develop film faster. When I was young I worked in a newspaper darkroom. With press deadlines we sometimes had to push things as fast as possible. If needed, I could go from an exposed piece or roll of film to a print that was ready for the engraver in about 10 minutes. But it was grainy, still wet and not permanently fixed. What you want is different. You want smooth tonal range, detail in the shadows and fine grain. Use 1 to 9 and take your time.

You should dispose of the developing mixture after using it once--using depleted developer will produce subpar results.

Ilford Ilfosol-3 once diluted is for one-shot use. Dilute it immediately before use and discard directly after development. The should be diluted 1 to 9 with water. How much chemical to use will depend more on the size of your developing tank. The Ilford Technical Data Sheet linked here will give information on how much to use for different tank sizes. https://www.ilfordphoto.com/amfile/file/download/file/572/product/1576/
