View Full Version : Sagging Bellows on Deardorff 8x10 Camera

I recently purchased a Deardorff 8x10 front swing camera with a new bellows. When using the camera for the first time I made a photograph of a building with the lens panel raised to its top position, the camera tilted up about 15 degress, and the front and back tilted forward to bring them parallel to the front of the building. I was using a 400mm lens. I discovered that I have a severe bellows sag problem in that configuration. I lose about an inch off the bottom of the photograph. Holding the bellows up as far as I can with my hand from the bottom reduced but didn't eliminate the problem.

Is this something that is just endemic to Deardorff cameras when used in this configuration or is this particular bellows perhaps too flexible? I can't tell what material it is but it feels like it might be leather. I owned a previous Deardorff that had an old (maybe original) but much heavier bellows and didn't encounter the problem though the longest lens I commonly used with that camera was 330mm.

The seller has very kindly offered to return the purchase price. If the problem is with this particular bellows then I'll take him up on the offer and look for something else. OTOH, if this is something all Deardorff owners experience regardless of the bellows material then I'll just live with it and try to come up with a work-around.

All bellows sag to some degree. The longer the lens the more likely the bellows will sag. That is why the corners of the ground glass are cut off. It is so you can look it to the bellows at the cut corners and see if you can see the whole round of the lens is visible. If the bellows is sagging the top would be cut off. Some photographers will hold the bellows up with their hand other use rods and clips on top of the bellows.

One of the nicest things about the Wisner Expedition 8x10 I own is that the bellows has 3 tabs on 3 different locations on top that connect to a pin on top of the front standard. This allows securing the bellows for different extensions and/or movements. I was wondering if you could attach something with velcro or similar to achieve the same effect.

It's possible that you have reached the mechanical limit of the camera. Did you use the sliding front panel or the whole-standard rise, or both?

Brian, I have had a similar problem with my 5x7 Deardorff. I didn't feel I was using very extreme movements at the time, but ended up with the same "clipping". Mine was not so much a matter of "sag", but the rear-most inside folds being in the image path. Let others chime in, but I think it's a Deardorff thing. Tracy

FWIW, I rarely encounter this problem unless I've racked the bellows all the way out to their limit, deploying the part of the bellows that usually nests in the back standard. 'Dorff bellows---mine and many I've seen anyway---don't have a uniform taper to them=the smaller, more tapered portion towards the front standard is more flexible than the boxy end that fits into the rear standard. Anytime I extend the bellows out to where the "union" of the two dimensionally different ends are hanging out there, I risk some drooping. As others have said, thats wat the clipped corners of the gg is for. A piece of card stock folded like a tent, resting on the bed and fitted into one of the pleats should offer needed support. When closing the camera, take care to "finesse" the boxy, larger dimiension rear portion of the bellows firmly into the rear standard and everything should be in order again. I stress that this occurs rarely and if your bellows sag most of the time something may be wrong with them

Brian, what happened to your new Ebony?

I regularly use a 450 Nikkor M on my V8 Deardorff without the problem that you mention. I do have bellows sag on my 12X20 with the same lens however. On the 12X20, I afixed a tab to the top of the bellows that allow me to support them from the front standard.

Deardorffs have two different bellows designs that I have encountered. The first and supposedly the original design were linear in their taper from front to rear. The more recent design has the taper extending to a point forward of the rear standard and the bellows extend straight out of the rear standard to that point. This is supposedly to allow better camera operation with wide angle lenses. My 12X20 has this same design and hence the bellows droop. Western Bellows will build them with either design.

As mentioned above, Wisners such as mine have three tabs on their bellows with a small brass ring that can go over a small post attached to the top of the front standard to prevent any sagging. This works well. You could attach something like this to solve the problem. Or you can try putting something below the bellows to support it during exposure. Another alternative would be to get some bellows Viagra...

The velcro solution works. I had a similar problem with my Technikardan at some intermediate setting after being set up in the extended position for a while. I got some self-adhesive velcro strips, glued two small pieces of the "loops" part on the top of the bellows (testing with the hand where pulling had the best effect) and on the back standard. A long strip of the "hooks" part can then be used to pull the bellows together. It always rests in my camera pack, which has velcro lining anyway so I can't loose it.

Thanks for the information and suggestions. Since posting this question I've played around with different combinations of front movements and have concluded that the source of the problem is the sliding front panel. When the panel is raised the bellows doesn't rise with it (not a defect, just the way the sliding panel works) and if the bellows is extended beyond about 14" it sags just enough for the lowest pleat to get in the light path. This happens only when the back is in vertical position, horizontal isn't a problem. And it doesn't happen with front rise because the bellows rises along with the standard. Also doesn't happen with tilts or with any combination of front rise and tilts, only with the front panel raised.

Since the circumstances under which it's a problem are fairly limited I will just learn to live with it and I should be able to raise the bellows with my hand or some object enough when I encounter the problem. I always check the corners of the ground glass whenever I employ any front movements.

Hi Bill - Nothing happened to the Ebony (though like me, it isn't so "new" any more) but it's 4x5, the Deardorff is 8x10, and I wanted to get back into contact printing.

Brian, The velcro idea has been adapted by Canham and actually works good for short lenses like the 90 and 120 for folks too cheap to buy bag bellows (like me) that enable you to take up the slack in the front by affixing the velcro hook tab on the front standard to various velcro loop tabs placed at different intervals on the top of the bellows fold.

For long lenes there are 2 inexpensive solutions to your problem, since I have encountered the same with my 19" Artar on my Century Universal and on my V8. The first is to attach velcro strips at different intervals on your bellows with a small hook that can be attached to a rod that you can place on top of the camera extending from the rear standard to the front standard. Not very pretty, but it does the job of holding the bellows sag out of the image area. However, that may not be a feasible idea if you are using an extreme rise on the front standard. Another solution is one that I use on both my 5x7 Canham and my V8. I measured the distance from the bed of the camera to the bottom of a fully extended bellows. Then I made several regtangular wire supports that are the same width of the camera bellows, made out of stiff wire (you could fashion the same from a wire coat hanger) that I wedge between the camera bed and the bellows to support it from underneath. You could even make several that are different heights. That really works great. They are cheap to make and I always carry one with each camera kit.

Old faithful is a paper cup. Either used full size or cut down to fit between the rail or bed and the bottom of the bellows. Next old favorite is a wire coat hanger bent to shape. Both eliminate sagging bellows.

of course, if the bellows is removeable, you would simply rotate it 180° and put the sagging portion on the top..
