View Full Version : Processing Tiny Sheet Film

Bear with me on this one. I want ideas on how to develop 6x6cm sheets of film cut from a 120 film. I ask here because this is the place for all things sheet film.

I've figured out how I'm going to cut film for my Hasselblad cut film back/holders. I have no idea how I'm going to develop it. I've thought about slotting it into a 120 reel, but am unsure how well this would work out in terms of things moving around. I may need to figure out some method of modifying a reel to keep the pieces of film where I put them. I also want to figure out a way to develop one sheet at a time in a single-reel 35mm tank.

I could do them in trays, but for now I have no darkroom and won't for the foreseeable future (I do everything in tanks currently, including 4x5).

Thoughts? Thanks!

You could make tiny hangers, and process in shallow tanks...

There are plastic coated clips too, you can get them cheaply in Staples.

You might try the taco method in a 120 tank, one or two sheets per tank; more "tacos" if you have a larger tank.
I'm not sure of the overall quality of this method, having never tried it myself, but some do swear by it when drastic measures are needed.

Is there a reason you don't want to get a 120 film back for your camera?

You could try the BTZS tubes or taco methods.

The Nikor sheet film tank will handle sizes down to 57mm high.

You can use a plastic 120 reel, but I would take the ball bearings out first to ease loading.

I have two 120 backs for the camera. I have the cut film back for experimental shots and other stuff that I'd like to be able to process one at a time.

Leigh - I completely forgot that the Nikor tank would adjust that small, which means I have one option. Still, if I could work something using less chemistry that would be a plus.

Trays.

Admittedly, the volume requirement of the Nikor for a single sheet (or even a few) is rather excessive.

It's not the size of the film (directly).

When you stand film up on edge in a tank, you need sufficient volume to fill to the top edge of the film.
That can be way more than is actually needed to develop that emulsion area.

Well I wasn't being entirely serious. When you mentioned 'Trays' , it was all I could do to stop myself saying 'ashtrays'.

I prefer not ever to employ smileys, but they can be useful sometimes...

I have posted this before and the darn things are rare I guess. I got 2 for $5 last year.

If I knew what they were called or who made them, I would search for more.

They can hold 12, I do only 6.

Are those regular 120-size tanks? And what are these called? Might be perfect for my needs.

Yes those are 120 tanks. they just fit. Unfortunately I don't know what they are called and I am not selling them. I use them a lot.

Hopefully somebody has a couple for you.

I use the nikor tank for exactly this purpose--hasselblad cut film. Note that the chemistry requirement for 2.5" film squares is about half that of a full tank--you need not fill the tank to the top.

They did this for the Mel Gibson movie, "The Year of Living Dangerously", when they had to make a fake passport. Ask Mel?

The infamous Yankee tank will also go down to that size. They're not so bad for stand and semi-stand development. However, I second the plastic spiral reel idea, it should be easy to load the sheets one-by-one into the spiral and move them inward once they've cleared the ball bearings. I don't think overlap would be a huge problem, the sheets shouldn't move with inversion development.

What about the ziplok-bag method? Requires darkness but you can use minimal chemistry.

Never heard of that, but sounds interesting!

I have tried ziploc with 8x10 xray, too tight in my bags, 5x7 worked great the same bags. If you want one at a time 2x2, small ziploc should work. Be gentle and use a new bag every time.

David,

If you are able to find a small dark space to work, small plastic food storage containers, available from most of the brands that make plastic bags and from Rubbermaid, work perfectly. Inexpensive, stack very compactly, tight-fitting lids. I love working with little sheets of film. Great idea to cut roll film into small pieces! http://www.thelightfarm.com/cgi-bin/htmlgen.py?content=13Dec2011

Heck, chop up X-Ray and do those little trays under LED red light.

David, we are local, I can easily spare, give away, 10 sheets of 7 x 17 X-Ray Kodak CSG. I don't use that size much at all. I got it to cut to 7x11 and 5x7.

I have cut it to 2x3 and I didn't scratch it. I did scratch bigger sizes. 7x17 sheets would yield 24 2x2 per sheet.

If you want it, PM me.

Randy, I may take you up on that once I get back from my family reunion (going over the weekend). I'll be in touch.

I seldom leave town until after Labor Day, less crowds up north.

Enjoy your family.
