Triptych Diptych Film Holder Adaptation

[glbeas]

The older darkslides are just metal. Get a caliper and measure one. Any competant machine shop can cut a sheet of metal to your specs.

...how about you take two pics in one negative, you develop it and then cut along the dark line and place them side by side? since the aspect ratio will be so "big" it should give a feeling of true panoramic.

True, but would that be a "true panoramic"? Wouldn't the shortened film diagonal cause the lens choice to be effectively altered to a more telephoto length? I wonder if this would be beneficial to the depiction of a true panoramic. Furthermore if the tripod head was rotated in order to not simply duplicate information which had already been exposed on film, wouldn't the differing heights of the film cause a misalingment from a true panoramic? At least it would seem to me.

OTOH there is no reason why you cannot make one dark slide with the rectangle on the far left, one with the rectangle in the mdidle and one with the rectangle in the far right leaving just a thin edge on each of the extremes as supposrt. so lets see the image would be 3 shots one right next to the other of measurements 6 7/8x3 1/2 in. Or you can do only two slides....the combinations are endless.

That seems to be what I said in my earlier post. Then it occurred to me, Why???? What is being accomplished by doing this?

Jorge said

I seem to recall a guy who did a series or "tryptich" one on top of the other, but I dont remember where.

There is/was a platinum printer that worked with enlarged negatives (studied under Sal Lopes) and he did print presentations by actually overlaying segments on each other. Is that who you were thinking of? If so I may be able to come up with a name for you for future reference.

Certainly I have not found a photograph where I can use the 12x20 vertical, but I do carry a smaller tripod presicely for those occasions so I can support the camera with two tripods.

Interesting, have you had your camera modified to incorporate a tripod socket on the front standard or on the side rail? If you have I may need to consider that for mine. What movements would you have if you were using the camera in that manner?

Some times we need to think out of the box, just because it has not been done does not mean it should not be done...no?

That may very well be true...if I could see anything accomplished by masking a negative in this fashion over simply making an exposure, printing the negative and then cutting the print to the desired number of segments...I would be interested in learning the benefit of doing the masking if you would be kind enough to tell me. I am always ready to have my knowledge broadened.

The other consideration that the original poster raised was mixing color and black and white. What would be wrong with making two exposures, one color the other black and white. Printing the respective negatives and then cutting the respective prints to the orientation and division desired. Is there something that I am missing here about this being the simplest and most straightforward way to accomplish the task desired?

Or am I not thinking far enough outside the box for this matter?

Ann, I do a lot of work with aluminum. If you want some inserts, I can cut them for you and use a flat black finish. I need to know the dimensions of the darkslide you have, including a thickness.

If you interested, send me a PM and I'll discuss the details. I could probably cut two for about $25 plus shipping, a few $ more.

Jim, can you make them any size? This would make a great way for me to get 8x20 and 11x14 out of my 12x20.

Looks like there have been some casualties to my vague and convoluted way of thinking about, and expressing what, I was wishing to accomplish.... I apologize for that...obviously I am the one that does not understand and lacks the experience to formulate the question.

I had initially made the assumption that the segments of film had to be in the same holder in order for the registration of the edges to link up precisely... as they were to be contact printed then blended. This also seemed to me to be the way to keep the visual perspective when using movements. It also seemed to me the way to keep all the elements organized. I also had other idiosyncratic aesthetic reasons...... if you refer back to my original question it is apparent that I was unaware of the concept of darkslide masking as a means of gaining different exposures.

For me there are now some wonderful new possibilities and methods that have arisen from this thread that I can explore with masking as well as simpler approaches to the colour and B&W mix. Thank you all for your kind input and creative solutions.

Jorge,


Send me some dimensions by PM. Need them to be pretty exact, within 1/32nd if possible. Plus I will need a thickness, probably best achieved with a caliper or a micrometer. Then you have to determine how you want them cut out, and give me those measurements. I am not sure of the price, but I will charge you my cost on the metal, about $12-15 to cut each one and then shipping cost. I use to be able to get plastic very similar to modern darkslide material. I may be able to get that (better alternative) depending on the thickness required. They won't have a handle, but can cut a hole to use to pull with and mark one side for exposure made.

Great Jim, I will measure Sandy's holders and send them to you, thanks!

I'll tell you the biggest problem I've found with ditychs and triptychs. It's uneven exposure/development at the edges of the negs (now that's probably due to development in open trays, but something to beware of nonetheless). Check here:

Annie, I've gotten to the party way late as usual but for future use here's how I would approach it. The old 711 holders are loosy goosy enough I think. I'd slide a piece of 5X7 film to the end. Maybe B/W. Then I'd slide a piece of 5X7 Velvia in and overlap the first sheet by an inch+. Now there's an equal 1/3 of the first piece. Then I'd cut my final piece (B&W paper??) to the dimension of the first and second piece and slide it in to overlap the middle piece. 3 different substrates will then be in position with equal 1/3rds of the full 711 when a single darkslide is pulled to make an un-interupted triptych (sic?) on all three pieces of material. The difficulty might be getting 3 pieces that will all "see" the same exposure correctly. PanX and Velvia are about the same speed but b/w paper is VERY slow. Confused??
