I never read the WPPD rules, so I thought I could use an image that I had taken near the actual day. That is what happens when you don't check things out! I took these on a great weather day early last week. As it says, it is the US Customs House in Charleston, South Carolina.

Homemade 4x5 pinhole camera.
Kodak Tri-X 320 film.

I'm trying something today, inside, but the exposure is loooooooong! I'm not sure if it will work, but if it does, I will submit it.

Incredible shots! Can you post some pics and talk about the camera a bit? I've been thinking of building one and would love to see it.

Here is what I posted at f295.org:

Okay, first post here, and first pinhole camera, with test image:

I built the camera out of 1/2 and 3/4 inch birch plywood. The distance from the pinhole to the film plane is 3-15/32 inches. The pinhole was made from a coke can, with a #12 needle. That should have given me a hole of 0.015 inches, with an f-stop of f220.

This camera is wide! I was about four feet from the first statue in the image.

The film is Kodak Tri-X 320, and the exposure was about twenty seconds. I developed it on Kodak D76 for 7 minutes at 69 degrees. This was about 10% less than normal.

Overall, I was impressed that I got a usable image! I had visions of either a blank piece of film, or something that was totally black.

From the standpoint of image sharpness, I'm not impressed. I have seen better images here. I may need to invest in a lasor cut pinhole.

My day was pretty much rained out as well. Only now has it started to clear up. Too late to do anything outside. I am trying something inside. Really long exposure, so I don't know how it will turn out. But, I will probably not develop it today. I have until May 31st to submit it.

Thanks Jon!

Did you wind up getting a laser cut hole? I'm only asking because you comment on the sharpness and the one thing that blows me away with images you posted above was the sharpness. I've always sort of dismissed pinhole because I'm a bit of a sharpness freak but seeing your results I'm willing to look at it again.

Jim,

That first test image of the kid statues was not as sharp as I wanted it to be, so yes, I ordered a laser cut pinhole. Since then, I have been amazed at how sharp pinhole images can be!

Tomas,

This is visually interesting, but how did you get this effect?

Hi John, by splattering fix onto paper before developing and developing with a sponge instead of immersion in dev.

On World Pinhole Photography Day, it rained all day. So, I was forced to find a subject indoors to photograph. Here it is, nothing really interesting, but what was available.

The interesting thing about this image, is that it took 9 HOURS to expose! A problem with reciprocity of the Tri-X 320 film I was using.

I'll have to try that sometime.

Before you do that, Jon, please consider using a sewing needle to drill a hole in a piece of brass shim stock.

That's what I did with mine, and I'm happy with the sharpness.

If you like, I'll get you the specs from "The Hole Thing" about what size needle gives you what size aperture.

I must confess that I have already purchased a laser cut pinhole. That is why my most recent shots are nice and sharp. I will try to make my own again, since it does add something to the images. I also tracked down a number of tutorials on creating handmade pinholes, so I think I have the information that I need.

Thanks,

Jon
