Post Yer Pinholes!
 
Let's see some pinhole pictures, any format, any camera, any medium. Include a bit of technical info if you want.

I'm very interested trying Direct Positive paper, how quickly after pre-flashing do you need to shoot and how soon after shooting do you need to develop?

I haven't done extensive tests on how the pre-flash fades over time. I do so while loading my film holders, just before going out to photograph.

I made a day trip out to the Very Large Array radio telescope in western New Mexico, with a 4"-by-5" pinhole box camera and film holders loaded with Harman Direct Positive paper.

I rated the paper at ISO 8. These exposures ended up being 30 seconds each, for a F/285 pinhole. Development was for 3 minutes in Ilford MG developer diluted 1+10 in a rotary drum.

Thank you Joe.

I have since removed the Sinar back, repurposed for another project. Made up a simple DDS holder instead. Main disadvantage is of course I can no longer use a multiformat 120 rollfilm back on the camera. But, hey I have 6x17, 6x24 and 6x6 pinhole cameras as well, so no real loss.

These were taken with the simplified camera:

Holga Pinhole 120 WPC
 
During the last two years, since I went back to film photography, I was attracted by Pinholes but didn'd try it until a couple of months ago. I went in the classic Roman Forum with my new Holga 120 WPC and a couple of rolls. I made immediately some mistakes during the first roll: i.e. not wanted double exposures (as I didn't advanced the film)... or let the cap on and so on.... :bang:
Well, for the second roll I was fiercely committed to not make mistakes... and everything went good. :)
I was impressed by the images and (seems) I got the right exposure and development time of a not so easy Adox CMS 20 film....

The results are in my Film Blog

Thanks to OP for the thread and great examples. I have to buy this paper and build 4x5 pinhole.

This one is from ebay seller of pinholes. M-mount cap, with laser drilled 0.2mm pinhole.

I bought a cheap pinhole body cap which the seller neither stated what size it was, nor included any documentation with it. It's sold as being "dustless" (though for the life of me I can't see how much dust would get through that hole), thus there is a plastic covering on the inside of the hole. When you look through it, is seems there is a lot of junk in the hole too (probably stuck to the "dustless" plastic covering). It may have scattered the light a bit, but then maybe the distance is wrong for the camera.

Nikon N80 on Kodak Ultramax 400 at 1/4 sec--f128 (lowest f reading my Gossen Luna Pro F would go to) I bracketed exposures, but the 1/4 sec reading was right on.

My WPPD contribution

My contribution

I find the irony of children clambering over these naval cannon turrets quite pleasing. The naval museum is next door (same building) to the national photography museum. The latter hosting the children's photography day, coinciding with WPPD. My kids got to take pinhole pictures, develop negs and make contact prints. They had a ball of a time. So did I.

Shot with this DIY effort, a 6x24 curved plane pinhole camera. Due to constraints with regards to the depth of the case, the curve is not semicircular, rather more elliptical, meaning that there is some vignetting towards the edges, but I rather think a pinhole image should have that sort of look anyhow.

Question for Joe V;
How do you make your pinholes? I'm blown away by the detail in the VLA pictures. While I know that for many pinhole users detail and resolution are not priority concerns I think it would be nice to maximize that quality in a 4X5 format. At least for myself I'd like to see a little more detail in my own 4X5 shots on photo paper.

JoeV 05-09-2016 14:41

@Zuiko85: Thanks for the compliment.

I use 2mil (.002" thick) sheet brass. I make a small, round dimple in the brass using a metal punch with a rounded (i.e. not sharp) tip. The center of the dimple will be much thinner than the rest of the sheet. You don't yet want a hole in the dimple.

Then, with dimple side pointing down, i press while rotating the tip of a thin sewing needle into the center of the dimple, just enough to make an even smaller dimple in the middle of the larger dimple.

Then use a careful, circular sanding motion and very little pressure against a sheet of 400-600 grit emory paper, dimple side down. Just to sand off the smaller dimple and form a narrow hole maybe 1/10 mm wide. Continue to sand, to widen the hole a bit, and make the edges of the hole thinner and sharper.

Then inspect under a loupe and carefully clean up the hole with the very tip of the sewing needle, if needed. You want a very uniformly circular hole with no burrs or other oddities, at the optimal size for your camera's focal length.

To measure the diameter, place the piece of brass behind a millimeter scale, with half the pinhole showing along the edge of the scale. Backlight the pinhole if needed. Then use your loupe and line up the left edge of the pinhole with a millimeter mark and estimate how many diameters will fit into 1 millimeter.

If you're targeting a specific diameter for a specific camera focal length, start with the hole smaller than needed and continue to sand against the emory, clean up the hole with the tip of the needle and inspect/measure until you get the right size.

Also, for sharper images use a larger film/paper format size; the images you mentioned were 4"-by-5" format. But too large of a format results in diminishing returns, since for a larger format the focal length, and optimal f-ratio, will be bigger, requiring extended exposure times, reciprocity failure and potential camera shake-induced blurring. I find 5"-by-7" is a pretty optimal format size.

~Joe

JoeV 05-09-2016 14:52

@Zuoko85: Another way to improve paper images is to pre-flash the paper.

For paper negatives I give it a slight, uniform exposure in the darkroom before loading into the camera or film holders, enough to render a very slight, off-white tone to the otherwise unexposed paper if it were developed without any additional exposure.

For paper negatives I like using grade 2 RC paper instead of multigrade paper, so the contrast isn't effected by the blue/IV of daylight.

For Harman DPP paper, I give it a pre-flash that's about half of that given to negative paper, enough to raise the darkest shadows in the image ever so slightly above unexposed paper black. I also rate this paper at ISO 8, and develop with liquid concentrate at 1+10 dilution for 3 minutes. I don't reuse developer for the Harman paper, but mix fresh each time; I'm using small quantities (100mL or so) in a Jobo tank.

~Joe

zuiko85 05-09-2016 20:42

Thanks Joe, I have tried the dimple method but I think my dimple, made with the head of a 1/4-20 carriage bolt, sanded smooth with finer grades, up to 1500 grit and then polished to a mirror finish with tooth paste. It think that set up makes too broad and shallow a dimple. I'll try a smaller diameter dimple. Also I've been using .005 in brass, I'll obtain some thinner stock. Funny you mention 5X7, that is the next size up I was going to build. I saw your falling plate design and it looks to be a good option. I've never cared for the fall off on ultra wide pinhole and usually opt for FL that produce a angle of view no wider than 70 degrees.

Thank you very much. I'm really enjoying pinhole photography, albeit with a digital camera. It has helped to dig myself out of a lull, photographically.
