Analog film photography and cameras

Last minute trip so didn't bring digital camera thread>>>>>>>>>>> with me. And I've got a box of out of date kodak elite chrome to get through anyway.

These are good

And is related to the discussion above, if it's ok to photograph without permission or not

Anybody bought a lazer/acid cut pinhole before? Any company recommendations?

I used the search but couldn't find an answer - where is a good place to get a camera repaired in London?

no, but what for? you can make them yourself really quite accurately.

brass sheet, sturdy pin/needle, extra-fine wet&dry to take the burrs off, magnifying glass and a ruler pref with 0.5mm markings on.

unless you want lots, that^ is a touch time-consuming.

Or grab an old SLR with lens cap, make a tiny hole in the cap, and put it in bulb mode.

wtf kind of accuracy is that?!
my method is for proper deluxe pinholes. the material of a lens cap is too thick.
I also have the formula for working out the best size for sharpest images dependent on size of camera.

I wanted serious accuracy because I'll be using my 5x4, got an idea in mind I want to try.

I've made pinholes out of coke cans in the past but I could never get them perfectly round.

Going rate is only about £12, knowing what I have is probably worth that.

The formula would be useful though

^^ for roundness I find going slow and spinning the pin works. keep buffing the burrs off and checking.

my dad worked out the formula from first principles, he still remembers optics and stuff, it's basically a compromise between 2 rules/behaviours: that the smaller you go, the sharper it is (since light behaves as a ray) vs diffraction making the image fuzzy with very small pinhole (since light is a wave). I'll dig it out.

great stuff!

Thank you.

Not much of a panorama fan in general,
but really like some of these, too, thanks for sharing!

Concearning the pinhole rocket science -
I had best results with *not *poking a hole through the coke can
(red bull or some ice tea may be thinner / better), but just make a little dint,
then go at it with finest sanpaper in circular motions to 'open it' (make a hole).

I heard of 'laser' cut ones but did never use them.

Back in the day I followed a flickr group of people who owned Zero Image pinhole cameras.

Dammit, I want to do pinhole again.

Actually I want to do it digitally now, to be honest -
but after what I've tried out so far you need a really big, really good sensor,
otherwise the image just looks blurry / shit.

another link you might find useful:

it's not that difficult to produce a perfectly round hole, the crucial thing is determining the right size for your focal lenght and neg size.
i was surprised to see that not always the smaller means sharper when trying pinhole on 4x5 camera.

Pre retirement, I had use of a 12W laser...

The camera is laser cut 3mm MDF, laser cut 'pinhole' in overexposed film, 5" x 3 1/2" paper negative in a curved holder. Most of the dimensions were either driven by the paper size (half 5x7") or came from "Adventures with Pinhole and Home-Made Cameras" by John Evans.

Kits of these were assembled by Year 9 students for activity week, loaded and processed under dark room conditions. Contact printing was demonstrated, but to save time the (often wet) paper negatives were scanned with a flat bed scanner and inverted using Corel PhotoPaint - not exactly traditional photography but somehow not digital either.

I doubt that I'm answering any (unasked?) questions - but it was fun at the time and I would recommend trying pinhole to anyone with use of a darkroom...

I played with the pinhole calculator earlier and if I worked it right, it recommends a 0.5mm pinhole at 125mm for max sharpness.

That isn't really that small is it, I guess i'll give it another go making one

I used the search but couldn't find an answer - where is a good place to get a camera repaired in London?

Sendean Camera Repairs.......as noted in the first post of this thread. Actually, I should have mentioned some others. I think MrCad can normally help as well, but they're deep in the south.

Cheers, should have looked back at the start.

Aperture are supposed to be quite good. Haven.t used them myself but will try next time something inevitably brreaks

Sorry, this is a bit OT, but someone may know.... I need a power cable for a 1930s 16mm projector and I have no idea where might sell one. Any ideas...?

try newton ellis in liverpool.

Do you know what voltage etc? If so you could put one together yourself?

Unfortunately it doesn't seem to be marked anywhere, but I'll have to research - there must be some generic voltages that these things were back then....
