I am a hack photographer, but I enjoy myself while doing it for the most part. I'm also a bit of an old-fashioned tinkerer, so any old camera that happens to come into my hands as likely as not tends to get taken apart.
While I've been shooting film for a while, I got it in my head that I needed a camera for Worldwide Pinhole Photography Day (28 April, in case you're wondering), so I built one (well, sort of).

I have to say I'm rather pleased with the results.

Anyway, here I am. Thanks for having me.

Very nice work .. Both the camera and the image!
-
Great! and welcome to the forum... :)
-
Great job and welcome 02Pilot. You obviously know how to drill a perfectly round hole.
-
Very nice project, and good results too. Obviously you know more than how to tinker with cameras.
Welcome.
-
Welcome home Mr. Pilot ;D
-
Thanks for the warm welcome.
Now that I've got some of the bugs worked out of the camera, hopefully I'll have some more images to show after WPPD next weekend. I'm very interested to see what others come up with.
-
You've come to the right place as far as tinkering goes. :)
Quite a few hackers and tinkerers here, myself included.
Looking forward to seeing more photos and camera hacks from you!
:) :) :)

Welcome! That's an impressive photo-I like it very much..

Welcome 02 :)

You are definitely all set to go for Pinhole Day.
Oh that my early attempts would ever turn out so well... Who am I trying to kid?... If any of my attempts would turn out so well... :frown:
Welcome! Beautiful work, and very interesting camera.

I've seen those little aperture discs on eBay.
I wonder if you could somehow hack a Brownie Hawkeye lens and replace it with one of these, and that way you'd get re-printable negatives.

The ones on ebay may be similar, but I actually made mine from shim stock and a #79 drill bit.
As far as simply replacing the lens on a Brownie Hawkeye, that was my original plan, but it doesn't work very well - there is significant vignetting due to the distance of the lens from the shutter plate. Unless you're willing to drill out the fixed aperture in the shutter plate, it will vignette. I was not willing to make that irreversible modification, so I went with the Plan B camera you see above.
-
I don't understand why it would vignette. Isn't the shutter completely out of the way when its clicked, especially if you are using 'bulb' and a modified cable release?
I'm not doubting you, I'm just trying to gain a better understanding. Pinhole is completely foreign to me, but I've got an interest in trying it out.

The problems with converting the Brownie Hawkeye are that there are multiple points along the way through which the light must pass, and that the lens is some distance behind the aperture in the shutter plate (the glass on the front of the camera is just a thin protective sheet; the lens is mounted in the film holding assembly). If you just pop out the lens and install a pinhole plate, the aperture (and to a lesser extent the sheet metal plate behind it) restricts the angle of the light entering the body to the extent that it will vignette. The same problem exists if you put the pinhole in place of the protective glass on the front of the camera body.
Now, if you put the pinhole plate on the front side of the shutter assembly, you can resolve the problem, but it's not as easy a conversion. Not saying it can't be done, but the idea of just popping out the lens and putting in a pinhole - which was the way I planned to do it, as it was both easy and entirely reversible - doesn't work very well. You do need to add a cable release and tripod socket as well, but these are both pretty straightforward.
-
02Pilot...you are entirely correct..tried this a couple times and it will not work the way you wanted it too..sad but true..You could put the pinhole in the very front but then it still has the light traveling past several obstacles that restrict the amount of light..you could take all the guts out and have a workable pinhole but not the shutter assembly...which I have done but it kinda defeats the purpose and makes just a 4 x4 pinhole holder and you have to find a way to keep your paper or film in place without those "guts".
-
Unless you put the pinhole inside the film chamber...But then you might get vignetting from the front "tunnel" you created.

exactly! and with this size I didn't want that much vignetting!
-
I opened one of my Brownie Hawkeye's today to get a better understanding of what you were explaining, and in fact everything y'all said now makes perfect sense.
-
I'm quite surprised you didn't get any vignetting from your Brownie flash20 as the pinhole seems to be very deep (at least from your pic). I've made similar conversion with a Kodak Cresta and had to change it later after huge amounts of vignette...

The picture above may be somewhat deceptive; the depth is really not that much (maybe half an inch), and the opening in front of the pinhole plate is plenty large to avoid vignetting. The shutter is directly behind it, and there is nothing behind that to obstruct the light from getting to the film. This particular Brownie model is actually quite well-suited to pinhole conversion, and the 6x9 negative is an extra bonus IMHO. Probably not as common as the Hawkeye, however.

Sorry - not sure how I missed this thread. A warm welcome to you O2 .... Looking forward to seeing more of your pics.

What a beautiful little pinhole cam and lovely image! Welcome, 02pilot!
