Same picture different camera.

The recent airing of a documentary on Vivian Maier sparked a debate between my wife and myself not on the wonderful pictures taken but about her camera equipment and what it has added to her pictures.

Vivian used a twin lens reflex camera (TLR). As the name implies it has a viewing lens of the same focal length placed above the lens in front of the negative. They are coupled together so when the viewing image is sharp it is the same at the focal plane. There are several things to note when using this type of camera. One of the oddities is the image; it is reversed, left is right and vice versa. So if someone or object is moving towards the left of the screen the camera will need to be moved to the right.  It is something that is a bit disconcerting when using the camera, more so for the first few times. The view screen gives no indication of depth of field until the negative is printed as there is no aperture settings. This lens design also exhibits the parallax effect this    is where the juxtapositions between far and near objects are seen  differently between the two lenses. This can be compensated for by moving the picture taking lens up to where the viewing lens is positioned.

With the idiosyncrasy of the TLR explained, it makes the street pictures she took even more wonderful. But I digress, this post is really about - 'does the camera add something of it's self to the picture?' In other words would you have taken that picture no matter what camera you were using?


I have canvassed opinions from other photographers and it has been suggested that the different working methods needed for different camera types and formats would indicate that the camera adds something of it's self to the picture. Or is it just perception? I will admit that certain cameras like the Lomo fisheye 2 undoubtedly adds to the composition in a particular way with its fish bowl negatives and distorted edges, this is also true of the pinhole camera with it's long exposures and blurred movement. These camera are chosen because of these attributes but the same could be said for the main stream digital, 35mm, medium, large format multi lensed system cameras. Maybe the premise is wrong and it is the lens that leaves its mark so to speak.

Lets be honest there are a multitude of factors that come into play when making a picture. With the camera lens combination playing the leading roll. I have not until the above question arose, made the same picture with different cameras and formats from the identical place. In my case it just does not happen.


Figure 1 Lomo fisheye 2 and figure 2 Nikon F5 with 28mm lens both 35mm Agfa APX 100 film @ ISO 100 are a couple of examples where I have made the same picture with a different camera in about the same place.






In conclusion the camera and lens you choose to use has an effect on the pictures you take therefore imparting something of is self on the end result.

Using the Agfa Isolette camera


Carrying on from a previous post on the Agfa Isolette The opportunity to use the camera was provided by a break in the weather - it cleared enough not to be soaked as soon as you leave the house.


The flip out film holder makes it easy to load a new roll of film. There are in built springs that provide friction, so the film is kept tort, keeping it as flat as possible at the focal plane reducing distortion. The film back clicks shut with a reassuring clunk. It also has a little red window in the back with a sliding cover in which to view the film numbers as you wind on. The film is advanced with a knob on the top right hand side of the camera that has a built in reminder to wind on after each exposure otherwise the shutter will not set.

To reveal the lens you press a button on the top left hand side. In this case the lens followed by the bellows leaps forward from the front of the camera with an enthusiasm that can knock it out of your hands if you are not prepared for such athleticism. Once the front is open you are presented with the five main controls: lens focus, a full set of apertures from F4.5 all the way up to F32. A limited number of shutter speeds: B, 25th, 50th, 100th and 200th A self timer and most importantly a lever that primes the shutter for release. The only other thing present is a connection for flash.

On the top of the camera is the shutter release that allows a remote cable to be fitted, a cold shoe for a range finder or other accessories and another knob that has four settings marked Col NK, NT, K and T. (I do not have a clue as to what they represent.) As far as I can tell it has had no affect on my negatives. It has a viewer and a tripod mount.



After I got used to the idea of guessing what the distance should be set to and then remembering to alter it for different views, I found myself taking shots quickly almost like an automatic. I did take light readings to start with but it became clear that the light levels were stable enough not to need checking for each shot.

It became clear that there was a problem once the negatives had been developed. Some how light was getting into the camera. Having checked it carefully before hand I should have carried on and cut a piece of light sensitive paper to fit the camera and left it for a minute to make sure. Once the paper had been developed in the normal way it would have shown that light was leaking in from the bottom right corner of the exposure chamber indicating a problem with the bellows.



I'm a little disappointed with myself for not doing this check in the first place. If I had followed through with the test, I wouldn't have had a duff set of negs'!. It would have made an interesting set of prints as the gremlin's face in the tree roots shows.
