Ilford PQ Universal Paper Developer 500mL

I’ve been using this in the tray for both RC and FB papers and the concentrate dilutes so easily that I’m not worried about inconsistent batches. It keeps my prints with nice, deep blacks and doesn’t exhaust too quickly during a long session. Definitely my go-to now.

Mixed up a liter at a time for tray developing and the solution keeps perfectly for months in a sealed bottle—no degradation between sessions. The liquid concentrate makes measuring a breeze compared to powders I've used before.

The 500mL bottle lasts way longer than I expected for tray developing, and the liquid concentrate mixes up in seconds without any fuss. It's handled both my RC prints and fiber-based test strips with solid, even tones.
