View Full Version : Probably a dumb question - how to see or adjust LF aperture from behind the camera?

Recently I have committed to shooting more LF and find myself in situations where it is impractical or even risky to walk to the front of the camera to change the aperture. For example at the edge of a drop off or rocky stream. Since there are no click stops on the shutters are there any tricks for
doing this? Maybe something as simple as a dental mirror?

Thanks

It seems to me if it isn too risky to step in front of the camera, it might be just as risky to try using a dental or other inspection mirror. I would suggest a strong panorama mount that would allow you to rotate the camera to face you, set the aperture and return the camera to its original position.

Thanks.

While I don’t have a pano head (and I am not really familiar with them, since I shoot panorama cameras), I do have a strong three axis geared head, but I don’t think I could maintain my composition rotating it back and forth - it has an angle gauge but it is hard to read and not always visible. Maybe a good properly leveled pano head would be accurate enough to work. I need to do some research I suppose.

A grease pencil or a bit of tape and a sharpie should help you return the camera to position. Just move one axis if possible.

I've used a piece of tape to mark the head position before swinging the camera around, but I've used the same lenses for so long that I can generally guesstimate the aperture by feel. Probably not dead on, but close enough for the B&W film that I shoot.

How about an erasable grease pencil? You mark it before you turn it to face you then turn it back and line up the marks.

Probably not relevant, but Sinar Shutters (Norma Green or Modern Black), and Sinar "Rabbit Ear" Lens Boards, allow setting shutter speed and aperture from behind the camera. There are basically four levels to the system; Barrel Mount with No Automation , Barrel or Regular Shutter Mount, with Aperture Cable Only (Direct Operating), and finally the Deluxe, Rabbit Ears with spring-loaded aperture control (this last one stops down the lens to taking aperture when you close the shutter blades. Deluxe Deluxe is shutter cable, closes the shutter and stops down the lens, when you insert a plate in the camera back. These do work well for me, I have some of each. I appreciated the operating speed when I was shooting in fleeting light

Question/problem was solved decades ago by Sinar shutter with Sinar DB/DBM mount lenses.

Sinar DB mount lenses have built in aperture only with the shutter mounted on camera. When used in combo, the lenses are full lens aperture at rest. The exposure aperture is set using a scale on the side of the shutter. Inserting the film holder into the GG back film holder slot presses on a cable linked to the shutter. This closes the shutter aperture blades preparing the shutter for film exposure. Pressing on the shutter's cable release winds the shutter, stops down the lens aperture to the f-stop set on the side dial, cycles the shutter to the set exposure time. Releasing the shutter cable resets the shutter and lens for another exposure cycle. Once the exposure aperture is set on the Sinar shutter scale, there is no need to reach at the front of the lens (nothing on the lens to set anyway), just the shutter open button on the side and cable release. This system is faster to use with the ability to reduce film into camera exposure errors due to forgetting to stop down the lens, close the shutter before exposure..

This Sinar system works on Sinar Norma to P/P2/X/F/F+/F1/F2..

Deardorff Studio Cameras had optional levers and knobs to adjust everything from behind decades before SINAR

Hard to find with all bells and whistles, 2 for sale right now, not me, Blue Moon has one

Tilts, swings even aperture, bulb and hose shutter allows any position

Front and rear focus

I considered adding complications last decade

Now it's exercise

Mine shoots to 75" bellows, to high ceiling, 5X7, 8X 10, 11X14 and upside down

people who are vision impaired sometimes have raised dots that have an adhesive. you might think about putting on on your shutter so either it stops your fstop ring or you know where to move it to from behind the camera. that said I documented a quarry and was on the rim 300 feet from the floor. I wore a rock climbing diaper and was attached to a deadman or tree so I wouldn't fall far. I always went around the camera to adjust the fstop. you might consider safety equipment if you are in a dangerous situation. the strap they used could take a 2000lbs dead drop.

With short lenses, you can look over the top of the camera pretty easily, but with long lenses that is nearly impossible -- unless you are Simone Biles.

Fortunately, when I'm near the edge of a cliff, I'm usually using a wide lens -- or if not, I can move back a foot or two to negate the problem -- and bump into my brother-in-law at the same time, by mistake, of course.

See the Mickey Mouse Cables? You can see that from behind the camera, it's easy to read the f/stop off of the color coded aperture cable. See the shutter speed scale on the shutter up top? It's also imprinted on the back side. Simple and it works without fuss. BTW these are both the Deluxe Deluxe spring loaded aperture controlled versions. On the lensbaord, see the little black lever with the red dot on it? Flip that and it stops the lens down to the preselected aperture. Simple brilliant mechanism and it works without fuss or bother.

After a while you could operate this camera blindfolded. Sinar Norma had an ad in the day, with a Guy in a blindfold, happily operating the Norma

To properly set up a camera on a tripod, the tripod itself should be level. Doing so simplifies situations such as you mention. I do it for EVERY shot so I'm always in practice,
With the tripod level, most heads will allow it (the head) to be rotated thus placing the front of the camera to face the operator. Before rotating, note carefully the image along one of the edges Make the adjustment, try the shutter, rotate back to the front and even stopped down there is enough light on the ground glass to reset to original position. Load the film, remove the dark slide and fire the shutter.

Here's an idea . . .

If you're on the edge of a precipice (hopefully still), then depth of field is probably not a problem. Suppose the correct aperture is f22. Then open the aperture to f8 to focus the camera, and it's easy enough to hold (without falling?) a two stop neutral density filter in front of the lens to expose the negative.

Maybe (??) the ND filter will have some slight effect on the final image? But, at least you'll be around to see the photograph after it's been processed.

Of if black and white, one could use a yellow filter with enough of an ND filter to make up the difference. For example, a Wratten 8 yellow has a 1 stop filter factor. So this filter, and a one stop ND filter would be needed to expose the negative.

Thanks for all the ideas !

I’m not talking about photos on the edge of cliffs usually, but more like at the edge of a river with bolders and slippery rocks to negotiate - the risk is getting wet or maybe a broken ankle and/or camera.

I think my tripod head will be accurate enough to swing to adjust and then swing back to the original composition (or damn close to it). I may need to mark it though it has some rough indexing that should get me close. Or maybe I need to move to longer lenses and shoot from a nice flat car roof!

Many thanks!

Jim Have you worked with those leveling bowls that allow you to level the camera with the bowl rather than having to mess around with the tripod legs? Are they worth it? I never can level the legs which require me to use the three way head if I pan the camera.

you could probably diy a little clip or magnet of some sort that you attach to the edge of the shutter to block the aperture slider from going past where you want to stop the lens down to, so you can do it without looking kinda like a preset lens.

What's a preset lens?you literally just have to turn the camera around, take a meter reading, set the magnet or clip, turn the camera back around, set your final framing and focus, stop the lens down and take the photo like normal. you can take a second meter reading to verify the first one if you're that worried about the light changing in less than a minute. preset lenses have two aperture rings. one adjusts the aperture and the other sets the minimum aperture the first one can close down to.

Large format lenses are not pre-set lenses. I don't know why that is brought up. Pre-set lenses were used primarily on early (1950-1960's) lenses before AUTO-diaphragm lenses were developed. Large format lenses don't need to have auto-diaphragms, and don't need to be pre-set.

I've taken lots of pictures at the top of cliffs. I've learned to be VERY careful -- especially in the wind. So far I've only lost a tape measure and a cable release.

a scenario like this where you want to stop a lens down without having to look at it is exactly why preset lenses exist and why i suggested adding something to the shutter of a large format lens to limit the travel of the aperture lever so that you can use it LIKE a preset lens.

I do this from time-to-time, but only when I know that I'm going to leave a little "breathing room" around my image for cropping. That way, any mistake in returning the pan head to its original position will be inconsequential. My tripod heads have a 360° marked scale on the pan movement with an index mark, so I just have to remember which mark to return to.

In most situations, I just reach around, unmount the lens, set the aperture and shutter speed, close the preview and cock the shutter and then remount it.

A mirror won't set the aperture and shutter speed or cock the shutter for you. You still have to either unmount the lens, set everything, cock the shutter and remount the lens, or rotate the camera around and back. With a bit of practice, either of these two methods works just fine.

In my experience, it's fairly easy to remount the lensboard plus lens on the camera from behind without changing the settings (especially easy if the lens is in a recessed board) unless you've got lots of bellows extension and just can't reach. In that case, rotating the camera around after carefully noting its original position works well.

Sure, you can use the mirror to check if everything is set correctly, but I don't usually find that that is necessary.
