MOD Developing Tank - Reel MOD 54

My 5x4 sheets sit perfectly in the reel without any curling or overlap, and loading three at a time takes about half the time my old method did. It's a clever bit of British engineering that just works, and the chemistry flows evenly across every sheet, so no more uneven development headaches.

Finally, someone engineered a proper reel for 5×4 sheets instead of wrestling with spirals in the dark. It loads flat and holds the film securely without any bending, which makes the whole process feel far less fiddly. Worth it if you shoot large format at home.

This little gadget turns the Paterson tank into a 5x4 sheet processor without any fiddly mods, and the engineering is genuinely clever. I've done three batches of film so far and every sheet loaded straight into the reel with zero frustration.
