What It Is

Ilford ID-11 is a Metol-Hydroquinone borax powder developer that yields up to five litres of stock solution. It is designed for black-and-white photographers who want fine grain, sharpness and balanced tonal rendition across all film formats. The powder form keeps the concentrate stable until mixed, making it a practical choice for deep tanks, dip-and-dunk processors or standard tray workflows.

Mixing And Use

Dissolve the powder to create a stock solution; one litre at working strength processes multiple rolls before exhaustion. For extended development and extra sharpness dilute the stock 1+1 or 1+3 and treat it as a one-shot solution. At 20 °C Delta 100 needs 7 minutes in stock, 10 minutes at 1+1 and 15.5 minutes at 1+3; Delta 400 at EI 400 needs 7 minutes in stock, 10.5 minutes at 1+1 and 18 minutes at 1+3.

Before You Order

Confirm you can store and handle five litres of mixed chemistry safely and that your tank or tray volume matches the working amounts you plan to prepare. Verify you have accurate temperature control at 20 °C and a reliable timer for the listed development intervals. This product is not for colour processes, instant-print materials or users who only need a few hundred millilitres of ready-to-use liquid developer.
