OLD FOLDING CAMERA TIPS... RF or Not

[julio1fer]

With film advance, my routine is to advance just a bit after every shot. Before the next shot I wind to the next number. When a number is showing, I'm sure it is a new frame.

I would like to be able to use o Cokin filter set up on my folder. Has anyone tried this? If you have, and it works, show us a picture.

Basically, 100 speed film gives me the widest number of exposure combinations in normal shooting conditions. I do not want to give up that pictorial control.

I use 400 speed and 25 speed film as special purpose film.

I, too, have found that 100 speed film gives me the greatest control and with ZI triplets is just fine at f11/f16 for hyperfocal.

I'm thinking of moving to 400 speed film w a two stop ND, however, as that gives me some extended shooting later n the day after removing the ND filter.

I am deliberate about concentrating on holding the camera steady: hold breath; press shutter release slowly and steadily, use a cable release for landscape shots (the shutter release is on the front plate beside the lens); use the self timer. I find that a full size tripod negates the size and weight advantage of the ZI folder, and most small, pocket tripods are not sturdy enough for the camera. I sometimes use a pen sized Minox tripod, which screws together ans so is sturdy enough for me. Below is a picture.

Anybody found a monopod solution that provides support and does not compromise the portability of the camera?

That is the sacrifice if you use 400 ISO film.

But you get better image quality if you have non-ideal light, because you don't need long shutter speeds ore open apertures that often.

For shallow DOF I would prefer a coupled rangefinder with a Tessar (or Heliar) type of lens. For these I would indeed prefer a ISO 100 film on good light conditions.

great topic, lots of useful info

Yes. In my Zeiss Ercona II the film is pressed against small bumps, and the spaces between them work like airducts. My Weltax has another type of airduct. I've never had a problem with the bellows sucking the film in. I wind the film after each shot.

Even better is if you cut a piece of plexi glass, or a CD cover to size and then cover one of the surfaces with the tape. Then you have a fine grained and bright viewing screen, and it's flatter than using tape alone.

Timely revival of this thread!

I just bought a pair of folders -the first of the breed for me. Keep the tips coming!

You can use a loupe on it because of the flatness of the plastic. Again... I've had good luck with tupperware, or other opaque surfaces from plastic bowls... matte side toward the lens, even with the film plane frame.

Yes! I even use a Scotch Magic tape surface for the viewing screen in my 6.5x9 Voigtländer Bergheil. The reason is that the film plane is appr. 0.5 mm inside the frame the groundglass rests against. I use a 1.5 mm sheet of plexi glass that is pressed against the frame, and inside the frame I have attached a thin but stiff sheet of transparent plastic with strips of doublesided tape, and the matte Magic tape on the outer surface. It works very well, although the tape is so fine grained that there is a "hot spot" of brightness in the center. But it's easy to focus on.

For my other plate cameras, Avus and 9x12 Bergheil I have ground my own groundglasses using old glass plates and Carborundum #600 grit. (Old glass plates have exactly the same thickness as the original GG's in these cameras and Rollei TLR's). And the glass can of course be cut to fit on the back of a folder, or even to check the focus on small format cameras. But matte tape on plexi is of course an easier solution and will not break if you drop it.

nice story man, however it is only valid if:
1. There is a venting hole behind the film plane on the camera body OR
2. there's a considerable sized empty compartment behind the film plane "filled" with air, to push the film away from the pressure plate when "vacuum" is created by the bellows.

I am not sure if any of the above points is the case for a folder...but i think not.
Vacuum doesn't suck in objects. Overpressure pushes objects into underpressured areas.

Here's a different kind of tip:
Don't discard triplet-equipped folders (and in general, mf cameras) and don't discard the use of these at large f-stops.
Some of them do create rather spectacular 3D-effects at f/4-ish apertures due to aberrations left in the lens system, which you will obviously miss at f/8-f/22.
No you won't get corner-to-corner sharpness at f/3.5 with a novar anastigmat, but your object in focus will pop off the image plane in a spectacular way...
(in the right conditions. Coz a brick wall won't pop off )

My latest folder with a triplet lens:



Sorry could not resist, and yes that is a modern multi-coated triplet on there. The camera does fold up, in a fashion, but I can not seem to get it in my pocket.

[Pherdinand]

you just need the right pocket.
