When your prints get bigger, your workflow needs to scale with them.
The Paterson 20 x 24" Developing Tray (overall size 24 x 28") is built for photographers working with large-format darkroom prints who need space, control, and durability.

Why darkroom printers trust Paterson trays
Sized for 20 x 24" prints → Generous internal dimensions → Comfortable agitation without chemistry sloshing over the sides.
Durable molded plastic → Chemical-resistant construction → Holds up to repeated use with developer, stop bath, and fixer.
High side walls → Helps contain larger volumes of chemistry → Cleaner workflow and fewer darkroom mishaps.
Ribbed base design → Elevates prints slightly off the tray bottom → Promotes even chemical flow across the paper surface.
