MOD54 1174296 Overview

The MOD54 Large Format Film Processor is a 4 x 5" sheet film holder for use in conjunction with a Paterson Super System 4 PTP116 three-reel developing tank. This holder accepts up to six sheets of a 4 x 5" large format sheet film and permits standard inversion-type agitation methods during development.

The holder is designed with a notch system, similar to 4 x 5" film itself, to facilitate easier loading and to ensure the emulsion side of the film is facing inward for greater protection against scratching.

Just about the only thing compatible with paterson tanks.

Pros: The bumps on the top make it easy to figure out the top from bottom in a change bag. It fits 6 in total which if you shoot a lot that's great for faster development. It's easy enough to work with in a change bag and fits perfectly inside a paterson tank. Negatives: During agitation, it's easy for the center agitation spindle to defy the friction with this insert. So when agitating sometimes it spins just the spindle a bit and not the film holder, if you're agitating hard. It doesn't have as much hold on the spindle as the film reels do. Sometimes during film loading in a small change bag it's easy to knock the negatives loose from their specific loading spots. If loading in a small change bag, consider the difficulty of catching the loader on the bag. Sometimes it's difficult to feel each negative in the correct slot, so when doing 6 it's more difficult to load than with 2 or 4.

Best value. Easier to load than 120 rolls.

I was unsure about purchasing this because of the mixed reviews of how difficult it was to load and film popping out of their clips. I just developed my first 4 sheets of CatLabs 80 in my 60 yr old Calumet 4x5. I am not unhappy with the process or results. I'm more unhappy with myself that I double exposed two sheets, and put some parts of a Cheerios box (I was practicing Schumpfleg) over my brother's restored 1894 farm house. It'll be the only old house with General Mills stamped on it. I did not have spare sheets of film to practice loading with, but I've loaded several 120 rolls into my Paterson tank reels. Even after practicing many times with the roll film, loading the sheet film into this holder was easier than my first rolls into the 120 reels. I did it in a bag with a rectangular cube I built to put into it to keep the bag fabric off the MOD54. I think it would be many times more difficult to do with the bag fabric always bumping against the sheet film in MOD54 and possibly dislodging it. It cost less than $10 to build the cube compared to a tent at $200+. Once the four sheets were loaded, I checked to see that they were in individual clips, and they seemed to be, but after developing I had a couple sheets that were stuck together on one side. I'm not sure if it was the hand-rotation agitation during developing or they were loaded that way. Hand agitation sounded pretty violent inside the tank, even though I used smooth, slow movements. I used the spin-stick for the rest of the process. Now that I have some exposed sheets to work with, I can experiment whether it was the agitation method or I just loaded them that way. Overall, this is the best value for sheet film processing in my opinion. I can do up to 6 sheets at a time for 1000 ml of developer. And I can use the tank that I have.

Great!

I already had the appropriate Paterson tank, so this was a pretty easy choice. It can be fussy to load with certain films--for whatever reason I find films with thicker bases to be a little harder--but any inconvenience is far outweighed with how easy it makes developing 4x5 film using materials I already had. If you're shoot a variety of formats, definitely give it a try.

Difficult to load consistently

I don't particularly like this reel but not necessarily because of the design. I'm a diabetic and for the last year or so having to test my blood sugar daily have made the tips of my fingers somewhat desensitized so I couldn't feel the edges of the film well, it was always hit or miss. Fortunately, I was able to trade this off for a Combi Plan T tank that is in like new condition.

Great addition to my Paterson tank Taco method for 4X5 sheets is ok but found I was messing up too many. This holds 6 sheets very nicely and I’m quite happy with it.

It's OK

I find it a bit hard to load. I've scratched a few sheets of film trying to figure out how to best load the thing, but once you get that routine down it's OK in use. It requires a liter of chemicals for each batch, so when only developing a few sheets it's rather expensive in use. On the plus side it can do six sheets at a time, so that's pretty good, and not too expensive in use. I guess it's OK. I don't love it, but I don't hate it either.

Develoing issues

I have been developing 35mm and 120 film for 4 years now and have never run into major issues. This system is incredibly unreliable - half of my shots are ALWAYS underdeveloped. I thought at first some sheets dislodged, and perhaps my agitation was too aggressive. After my 4th spin with MOD54, I have, yet again under developed negatives. I will not waste another exposure with this product. Money and tine, in the field and development are completely wasted.

Will this work in the larger Paterson tanks (5 reel) if I were to put an extra 120 reel or 2 35mm reels to take up the extra space?
Asked by: Edmund
Yes, you can use the MOD54 Large Format Film Processor with 2 additional Multi-format Reel with 35mm film or 1-reel on a 120mm film position. The MOD54 Large Format Film Processor will take the space of 3 reels inside the Paterson Multi-Reel 5 Tank (Super System 4).

It's made to fit a Paterson tank - not sure if it will fit a Unidrum. But it can easily be loaded in a changing bag.

Does this have to be fully loaded with 6 sheets to use?
Asked by: Phillip
No, as previously mentioned, it can be loaded with 1 to 6 sheets, but you will still need to top it with the chemistry. This thing is a dream!!!

Unfortunately I don't have a Jobo tank so I can't say. I've only used it with a Paterson and it's been great. Wish they'd invented it years ago.
