Hi everyone! Could anyone tell me if I can use a 5x7 plate camera with sheet film and if so, what adjustments if any need to be made? Thanks in advance for any and all help! MC.

The 10x8 I have was a plate camera originally, and I use film without any problem, but it may be beginners luck. Some people have told me to place the neg onto a piece of glass from a clipframe, and possibly use some kind of temporary adhesive to keep it from moving. Of course, you dont want adhesive anywhere near the emulsion side.

I'm looking to do the same thing with a 5x7 field camera that was apparently a half-plate, so I'll be interested in others' views to this.

Thanks for the info Ash! I should have the camera today and I'll give it a try. Thanks, Mike.

Most likely you can use any camera made for plates with the same size sheet film, if you have plate holders for it. You need to either find/purchase film sheaths (fit in place of a plate and hold a film sheet flat and in position) or fabricate something that does the same job (simple version, a piece of plate glass with post-it type spray adhesive to hold the film flat on the glass). Do be careful, however; 13x18 cm is very close in size to 5x7 (but not identical), and if the camera was made in Europe is a much more likely size for a plate camera than 5x7 inches. The 13x18 film is obtainable, in a limited number of emulsions -- slightly more limited than 5x7 -- in the US; in some parts of Europe, it's the other way around.

I use a 13x18cm plate camera with film. I stumbled across some sheet film adapters, both 13x18cm and 5x7". One of my three plate holders doesn't like the 5x7" adapters, they are just a little bit too small. The others work great with either size. I've shimmed the ground glass 0.3mm back to compensate for the thickness of the "lip" of the adapters.

I also use 18x24cm, 24x30cm and 30x40cm plate cameras. With the two largest I glue the film to glass plates using "Post-it glue", or (famously) jam.

jam?!

i take it you lick off the excess? :D

I had forgotten to bring the spray glue, but had remembered the 30x40cm camera and plate holder. A few small smears of blueberry jam (get rid of the seeds!) did the same job and has the added benefit of being water soluble. Next time I forget the glue, I think I'll try orange marmelade instead - it's even stickier!

See if you can borrow a 5X7 filmholder. In many instances they will fit right into a camera originally made for plates.

P.S. If you can't find one in your area, I will loan you one.

I have a 5x7 plate camera which I use with film. The plate emulsion plane is not the same as film plane, which means that focusing adjustment is required when working with film. The previous owner machined an aluminium frame which can be inserted in between of ground glass and camera body. The frame was designed to excatly compensate the film/plate plane difference. It works perfectly.

Jan

I have a few old (make that very old) 5x7 plate holders. Am willing to part with them. Any interest?

I have several old plate cameras that I use with film. I use the wooden plateholders that came with the cameras, and cut a piece of plastic to the same size as the plate aperture. It is then pushed against the rebates in the holder by the spring in the holder (never seen an old plate holder without a tensioning spring - yet!), so if you get the proper size film or cut it to the right size for the holder, nothing 'sticky' is necessary. Also, if you use the original holder the surface of the film will be in exactly the same plane as the surface of the plate would have been, so no focus problems.

Regards,
Neil.

I agree with Neil - for 5x7" and smaller, nothing "sticky" is necessary. Sometimes it can be a good idea, though.

But a 9.5x12" sheet film is a big floppy thing, 12x16" even worse. Stickiness is definitely necessary to avoid "film flop"!

Steve I would be interested if you are in the UK, as I currently do not have a working paypal account

Hi everyone thank you so much for the wealth of information and knowledge! Now can someone tell me the thickness of glass that went into the old holders, or were they all different in thickness? I have never seen an actual glass plate. Thanks, Mike.

Mike - I just measured several old plates (Ilford and Wellington brand) and they are barely 2mm thick. The glass I get from the local picture framers (far cheaper than buying from a glazier, especially if you get off-cuts and cut to size yourself) are more or less the same thickness.

Regards,
Neil.

Ash,

I'm in California, USA. It'll cost more than they're worth to ship 'em across.
