View Full Version : Anamorphic Viewfinder... ?

one of the biggest problems with the black box anamorphic camera has been my inability to visualise what the images were going to look like and hence aiming it to include the objects I wanted in the frame.

I now have the solution thanks to an offhand comment by staft that got me thinking...

I decided that if I got a cylinder with the same dimensions as the one I used in constructing the camera, incl a window cut out the side, that if I put a hole in where the pinhole was in the camera I could look thru and what I'd see thru the window would be the same as what the film would see.

I've tested it and it works pretty well and now I can set up pictures with a reasonable degree of accuracy

I put a small hole in the far end of the cylinder and what I see thru that gives me a reference point to aim the camera at... I line up using an edge of the camera which is parallel to the axis of the pinhole aperture. A second check is to hold the aiming device against the camera such that aiming cylinder is parallel to the cylinder inside the camera.

Suddenly I can get a handle on pretty much everything that's going to be in the frame. It may be rough but it works and that'll do for me.

the pics show the device by itself, in use against my eye and strapped to the bottom of the camera [where I've been holding it to check framing]

the other 2

after some consideration, I've decided this works almost as well as the finder in my fav Diana plastic cam (but I'll admit it's harder to use) Attached files http://f295.f295.org/uploads/view3_3261.jpg (http://f295.f295.org/uploads/view3_3261.jpg) http://f295.f295.org/uploads/view4_1798.jpg (http://f295.f295.org/uploads/view4_1798.jpg)

you are man of the year for all of us anamorph fans! the tom edison of distorted photo anachronisms! the marie curie of retinal culture! when my current camera is complete (started last night) i will make one of these. thanks, fellow spaceman!

and to think i way toying with a digital viewfinder ... what's with the black tape ? remember the old ''stag'' movies where the ''actors'' had black tape over their eyes ?

I'll add another cautionary comment or two:
like any non-slr finder it is a bit of an approximation and the "vertical" angle of view is narrow enough on the camera that you have to be carefull... it is fiddly +++
also, using this in a public place will make you look like a raving loony so expect a few stares and move on before they call the guys with the really big butterfly net!

I don't think I ever got to go to those kinda moveis... :-/

black tape? which bit? there's black tape everywhere....!!!

thanks for the vote of ugliness...

but I'm gettin' very attaches to Miss Pacific 1952.... all three of 'em !

Black electrical tape....Red Green would be so disappointed!

Interesting concept, glad to see it works.

a technological breakthrough in the "science" of anamorphic pinhole cameras!

My additions to a design offered by Andrew
I suggest to use a convex mirror. Attached files http://f295.f295.org/uploads/wf01_2741.jpg (http://f295.f295.org/uploads/wf01_2741.jpg)

Igor's solution is too beautiful...kind of waters down the extant ugly factor.

I have been hoarding identical cans in pairs, envisioning a twin-hole anamorph (non-reflex). I was going to make a translucent viewing screen, like maybe out of a plastic milk bottle.

so elegant... so inventive.... a triumph of engineering and lateral thinking !!!

so, does it attach to the camera in place of a cap over the pinhole ???

The question set by Andrew, has given me food for reflections... I have made some experiences and have simplified a design. Now the view-finder can be used as a cover for an objective. Attached files http://f295.f295.org/uploads/wf0201_184.jpg (http://f295.f295.org/uploads/wf0201_184.jpg)

Just way too cool.
Amazing!
Thank you-- perhaps you could please apply your genius to solving the world hunger problem?

Wonderfull Igor ! I had little succes with my anamorph camera, I think about building a viewfinder of your design soon. Thanks for sharing :)

Can somebody explain the relationship between the dome viewer and the Anamorph pinhole. If I had the viewer flat in my hand, and I was looking down on it, is that roughly the image I would get if the pinhole was pointing straight ahead?

Andrew, Igor, polka - the world owes you three a debt of gratitude. Paul - are you saying that you can find a convex mirror in packaging for Christmas treats? Do you have a brand name that we can look for?
