Developer solution Ilford Ilfosol 3 500 ml

Ilford Ilfosol 3 is a liquid black-and-white film developer supplied as a 500 ml concentrate. It is an enhanced formulation of the general-purpose one-shot developer Ilfosol S and is optimised for medium- and slow-speed films, delivering fine grain and good sharpness when used at full film speed. The concentrate is diluted for one-shot use but can also be mixed at higher dilution for greater economy.

Advantages

Ilfosol 3 provides consistent tonal range and reliable performance across a variety of black-and-white films. When used with medium- and slow-speed emulsions it produces reduced grain and improved acutance. The product is supplied in a 500 ml bottle that is economical for multiple development sessions and easy to measure thanks to its light-coloured container.

Suitable for

• Developing medium- and slow-speed black-and-white films (e.g., Pan F Plus, FP4 Plus, Delta 100)
• General-purpose one-shot processing in small darkroom labs
• Users seeking fine grain and good sharpness at full film speed

How to use

Mix the concentrate according to the manufacturer’s instructions for one-shot use (follow dilution and temperature guidance on the label). Use standard film developing procedures: measure and mix working solution, pre-wet film if required, develop for the recommended time with gentle agitation, stop, fix, wash and dry. For greater economy, a higher dilution such as 1:14 can be used with many films, with a small compromise in image quality.

Usage recommendations

Follow Ilford’s recommended dilution, temperature and development times for each film type to achieve consistent results. Wear appropriate protective equipment and dispose of chemical waste according to local regulations.
