Paterson 13x18cm Developing Trays are built to withstand chemical exposure, these trays ensure a reliable and long-lasting performance. The trays come in three attractive colors: red, white, and gray, catering to your personal preferences and needs. The Petarson 13x18cm developing tray features a finely designed spout that doubles as a thermometer holder. It serves multiple purposes, making it ideal for developer, stop, fixer, and hypo-clear baths, as well as general usage. The tray’s bottom is thoughtfully indented, providing stability and preventing photographic materials from adhering. Crafted from a chemical-resistant material, it can withstand even 60% acetic acid.

Cleaning the Petarson developing trays is effortless, and their stackable design allows for space-saving storage. You can choose from various sizes and colors, including grey, white, and red.


If you are buying these to process 4×5 or 5×7 Dry Plates we would recommend you to order 4 Paterson 13×18 developing trays in following colours:

  • WHITE for Developer to clearly see the magic of black negative slowly coming into the frame
  • RED for the first Wash.
  • GREY for the fixer since the dark colour will help you determine whether or not you have removed all unexposed silver halides that slowly transform from white to clear.
  • WHITE,RED or GREY for final wash bath since you will be turning your lights on after fixing the colour does not play a big role anymore.
