So I finally got my big order... Parts for my home made 6x17 medium format panoramic camera.
I'm very excited and slightly disapointed at the same time... And I still have lots of work before I can take photos with this sucker...
First, BSF is just painted WSF??? I had no clue... Makes sense for production ease, but I would have liked to know...
Second, tolerances are really not what I expected... I guess the black paint is mostly to blame. It's not so bad that it can't be fixed by some sanding, but I expected tighter precision...
Last, the 10 day window was missed, by not that much but missed... just a bummer since the test parts tool much less time to arrive, but at least it's here now...
I started integrating some external parts for the film winding mechanism, taping holes, etc, but it will definitely take longer than I thought...
I'll keep posting on progress...
parts ordered
with the other things that need to be somehow attached together

Hi there,
An ambitious first project!
The BSF is dyed as per the materials page, maybe we need to call it dyed strong flexible: Black in the ordering options?
http://www.shapeways.com/materials/white_strong_flexible
Please do keep sharing your progress along with any issues you have so that we can learn from them..
Best of luck

Yes, please do that...
I missed it too and was very disappointed with my last order.

Thanks, Duann.
Yes, it would help.
I'm not sure how I missed that but it would be helpful to have it more clearly stated at the ordering stage.
I just needed the inside of the parts black (to stop light from bouncing around in the camera) so I could have painted them and saved myself about USD70...
Oh well, next time I'll read more thoroughly 
It is indeed an ambitious first project but oh so gratifying

Oooh one other thing that I forgot about BSF...
So in the picture above it looks dark grey more than black... But in daylight, it actually looks deep blue-purple grey... Not black at all... I was surprised... Not sure what the issue is, bad dye batch maybe?
Not a real problem for me since this is a functional object, not art, but an artist designing something that would be expected black might have an issue if the print turns out with a purple hue...

Uuuugh... the test roll is a total fail... not sure what happened... most likely I mishandled the film. Or the camera has huge light leaks. Or the lab totally messed up... No way of knowing, the whole roll is basically blank... And I won't be able to try again before next weekend so I won't know what the issue is for another week... 
Anyhow I'll post as soon as I have something tangible...

I just figured out the problem... the material is not light proof...
I had assumed that BSF was solid black. But since it's dyed WSF, it is translucent... I can see light from a flashlight trough even the thickest parts of the body (5mm+ thick).
Now what? How can I fix this? I'm a bit lost guys... Any idea besides wrapping the whole thing in gaffers tape?

Cover all with metal plates or glued foil (inside? outside? space and uglyness will tell...), to be sure no light ray can pass, then paint (or even flock then paint) it matte black to be sure if it passes, it doesn't bounce much.

Thanks for the reply stannum.
I was thinking about foil, but using it inside would create more problems than anything... I found a flocked light trapping material for telescopes, but I'm not sure I have the space inside...
I may just end up layering foil on the outside and maybe spray paint over it...
Any other ideas?

What about a thick coat of a black epoxy paint on the outside?

Thanks Youknowwho4eva.
I know nothing about paints, etc, would it make the thing light proof?
Define thick coat... how easy/hard is epoxy paint to apply? does it come in spray form?

hi @mgrynberg,
Just wondering if you ended up painting the camera, and if this worked stopping the light leaks, as I'm looking to do something similar.
Cheers

Hey Will,
I didn't have a chance to get this done yet.
Right now I'm looking at Krylon Fusion paint which is specifically made to bond with plastics, but I'm not sure if it will make the camera light proof or how many coats I would need...
I'll post any progress when I get around to doing it...
Also let me know if you figure anything out...
What's your project?

Good to know that the BSF is not light proof ... I have been thinking about revitalizing my old cameras.
You could always go along to a car spray painters - they could do a nice finish that would be quite thick.
Can't wait to see how your finished camera ends up looking like!

Yea, im thinking this is what i'll end up doing as well, I'm doing a couple of tests with some simple black spray paint on clear plastic, to see how opaque it gets and will let you know how it goes... Or like berrynaut said, maybe getting it professionally painted is the way to go...
I was also thinking maybe some of the other materials (maybe the black detail or grey robust) might give a more lightproof finish, but at any rate the extra cost of these is prohibitive for me.

I'm looking to make a simple 35mm Pinhole camera, (have attached a render), and am thinking of getting it printed in WSF, (as it ends up being ridiculously expensive in any other material) and painting it black to get it lightproof.

Very cool project!
What are you using for the pinhole itself?
Is that white lever at the end of the cone a handle for a dark slide to act as shutter?
How will you be keeping track of film advance so you don't overlap images?
The wall thickness obviously plays a big role in the light tightness... On my model, most surfaces are 3mm thick and definitely translucent. some parts that I built up to 6mm for reinforcement are good tho...
Also - and this really depends on the kind of tripod head you will be using - I built an arca-swiss type plate into the model to use straight in my tripod head without having to screw a plate, and it really works great...

There are a few things I would do.
1) Print in WSF
2) Let sit in a black die bath overnight so the die soaks all the way through instead of just outer layers.(you will need an insulated container to keep the die water warm so long)
3) check opacity of material. If good enough stop
4) coat inside of parts with black electrical potting compound. This is a 2 part epocky that is fire retardant and light retardant. You will have to do 1 side at a time as it will flow with gravity and takes 24 hours to completely harden(unless you put in the oven then it takes an hour but don't think WSF will take heat).
Actually I would probably try to print out of PLA on my printer and skip to step 4 but I assume you don't have one if you are making large prints like this at shapeways.

Thanks for the idea mctrivia.
I unfortunately don't have space inside the camera for a layer of any material. It's a very tight squeeze there...
But I will investigate the potting compound for an outside layer.

I've painted plastic prototypes before that needed to be totally opaque and the solution that worked well for me was to spray a thin but even coat of silver on the critical areas then cover that with a coating of very flat black.
It sounds strange but works well at keeping light out.
I suppose you could liken the silver to a coating of alum. foil.
Nice work by the way!

Thanks for the tip, Casey.
I have still to try an outside coat of a product called milliput that was recommended by some modeling guys in a shop here, but I like your idea better...
I'm also gonna give it a shot because it would enable me to coat the inside of the camera and keep the outside looking good...
Any details on the kind of silver paint? Just regular krylon type spray or something else?
Thanks again!

Marc,
Try Krylon Fusion spray cans:
Textured Shimmer Silver #2520
and
Flat Black #2519
Silver on first, then black over that.
This SLS nylon material needs paint designed for plastics.
Also, apply a first coat of silver and test to see if it is light-resistant enough, if not then apply another coat of silver until you're happy, and finally spray enough flat black to cover up the silver. Go easy though, It rarely takes much paint to do the job.
I'd be inclined only to do this to the inside of these parts as well.
Good luck and let us know how it goes!
Casey

A coating of Milliput? I use that stuff very often, and it's not suitable for thin coats. It's an epoxy putty, not a spray or a paint. I would stay away from it for this camera project.

Treadshot A1: thanks for the comment. I know it's not a spray solution, it kind of my nuclear option since the modelling guys throught I could not have full opacity with paint only... If all else fails, as a last resort I would coat the outside of the camera with milliput and have me a nice little rock looking camera
Casey: thanks a bunch, I'll definitely try that silver spray first

Treadshot A1: have you ever used milliput slurry? That's probably what the modeling guys were talking about.
Edit: that you can "paint" with milliput doesn't imply that such fine coat will be opaque enough for this task. Paints with lots of pigment, or extras like mineral or metal particles, are probably a better approach to blocking light.

My pleasure, I'll be watching you're camera project closely as I'm wanting to design and make functional parts for myself using Shapeway's materials. There are a lot of people designing and making parts here that are asthetic or artistic but not many people like yourself trying to make mechanical devices.
Thanks for sharing your progress!

Hi all,
Just a quick update, I finally got to testing Casey's recommendation...
And compared to the other fixes, it's definitely the best given my manual skill level...
I went a bit nuts on my test sample with 3 coats of silver texture, but it's definitely opaque now...
So next step, break down the camera a spray it...
Will update when I'm done...
Thanks again to all of you who sent me all the tips and precious advice...

Are the light leaks from a general lack of opacity, or are they from gaps in joins? If the latter, could you use some kind of gasket material, or black velvet perhaps?
|
|
|
| Re: HELP! Panoramic camera [message #37567 is a reply to message #35631 ] Fri, 28 October 2011 21:54 UTC |

I also suggest that the light leaks can be solved. The gaps and joins must have seals or gaskets. Also in the WSF you were looking for visible light leaks, also consider UV and IR when in daylight!
Some Krylon silver and other metallic paints are not real metals so are opaque in certain wavelengths. Consider these spray ons below and or using a simple electroplating for a full metallic cover.
hope you don't give up!

Thanks for the suggestions, Ed.
Right now I'm trying to spend more time actually shooting rather than being at home trying to fix this camera...
Might get back to it in the future if I have time to spare...
If I do, I'll definitely look into your solutions.
Thanks again!

So how long will it be before the phrase "I got my roll back" means absolutely nothing to anyone reading it....?
I'm a former professional photographer and just love black and white pic's. Great project and congrat's.
