Making myself a 4x5 pinhole over the weekend, a first for me. Using the same sort of plant pot from IKEA as for the P+S I made a few years back. And a Cambo 4x5 back I had lying about. Hope to finish it tomorrow. Have however no film for it at the moment, and at $100 a pack of 25 locally I see myself ordering from overseas. In the meantime I will test it out with a 120 4x5 back, 6x12 I suppose.

As far as I can work out it will be a 122mm f244, i.e. pin hole of 0.5mm. Pin hole a bit on the big size from what I've been able to discern. Should idealy be 0.4mm or less, and the aluminium taken from a thick skinned tin may make for poor results, we will see. I must admit most of the effort so far has been put into making an internal shutter, actuated by a cable release. Will post pictures when done.

If you're concerned about your actual pinhole, remember you can put it on a scanner to measure the size of the hole in mm and to check the quality. In my view having good roundness and being free of edge burrs is more important than having the perfect size for your focal length.

Ezzie · « **Reply #53 on:** April 07, 2013, 07:41:32 AM »

Thanks Sandeha. I did just that, since I don't have a drill smaller than 0,8mm, I had to use a punch and 1200 grain emery cloth and then measure the diameter by scanning afterwards. A bit of trial and error and I think I may have something to go with.

All this pinholia started me on a search for a new toy as sometimes the superwide of the Pinhole Goose can be limiting.
Now Pinhole Gander had to be about 35mm from a 35mm camera perspective and after a search here she is with a quick test shot just to check the parallax viewfinder.#

Jojonas, what can I say...!

Well, the camera is getting there. But to be 100% ready I need to find a cable release that

doesn´t have a kink in it
the sheath doesn´t come undone
isn´t too long, so that it once it meets the resistance of the shutter spring it expands in the sheath

Maybe I should have opted for a lens cap off, lens cap on shutter

The shutter should be quite simple, but the return spring evidently shows up any weakness a cable release may have.

Below you can see the shutter mechanism out of the camera. The shutter is in front of the pinhole, meaning you see the rear of the shutter and the pinhole. The other pictures show the shutter as seen from the outside, open and closed. The camera itself, front and rear. The back is a Cambo I think, says its made in Switzerland. Anyhow, fits these IKEA plant pots to a T.

Shot a roll of 120 / 6x12 late this afternoon, will develop tomorrow and see what they look like.

Ezzie · « **Reply #56 on:** April 09, 2013, 07:30:06 PM »

Considering I had to remove and insert the dark slide as a means of shutter, making the camera shake for half the exposure, I am not to displeased with my two first pinhole frames ever. These were shot on 120, 6x9 and 6x12, but I hope to get some 4x5 in house before the 28th.

The 6x9 is and 8s exposure, the 6x12 is 12s.

Since taking the shots I have made a slightly smaller pinhole (0,4mm vs 0,5mm) and fixed the shutter.

Ooh, rather nice. Especially the second one.

Urban Hafner · « **Reply #58 on:** April 09, 2013, 07:58:17 PM »

That's really not bad at all Eirik! For me it will be interesting to see how long the exposures with paper negatives (ISO 3) and a f/400 pinhole will really take. I can only hope for good weather

Ezzie · « **Reply #59 on:** April 09, 2013, 08:45:10 PM »

Thanks boys. These had the advantage of being shot on Acros (developed in Rodinal 1:50). I couldn´t be bothered to calculate for reciprocity, and Acros is a safe bet up to 120s.

Ezzie...those are terrific images...Would love to see your 6x12 camera..

Ezzie · « **Reply #61 on:** April 11, 2013, 10:23:04 AM »

Thanks Diane.

The camera is the 4x5 pictured further up, I just didn't have any 4x5 to test with, so I used a 120 Graflok back in the meantime. I'ts undergoing a paint job right now, but I hope to take it out again soon.

Pinhole Day is just one week away!

I'm ready to go, how about you all?
I'll be going on the road with these.

Two homemade ones from wood scraps and the "dicey" ones from repurposed craft boxes.

Recycle, reuse, re-pinhole!

I´m ready. Just need to negotiate with wife to get time to do some shooting. This (also posted in the weekend thread, sorry) the last test shot on my DIY 4x5.

Now confirmed the diameter and f-stop are correct
Now confirmed that Shanghai film is like any other 4x5 film, notch upper right in portrait orientation
Now confirmed that I can use the FP4+ reciprocity chart for Shanghai 100
Now confirmed that R09 1:50 for 13:30mins gives nice tonality
Now confirmed I can merge two halves (Epson V500 doesn´t do 4x5) in PSE

Now I need more film holders, more PrintFile neg holders, and I would like to upgrade to a V700 methinks

just a few pinholes in my bag of tricks..( for demonstration purposes only) and to inspire everyone to get out there and shoot a pinhole next Sunday!

jojonas~ · « **Reply #71 on:** April 22, 2013, 10:47:45 PM »

this thread is starting to become a real good read

things are heating up! the big day is coming~

today I took the 6x9 pinhole camera from sandeha and loaded it up with some 35mm polypan f+ film. we'll see if I can hold my trigger finger on that one

in the mean time, here's a scan of the neg from that earlier shot. I'm surprised the paper registred so well in the shadows~

The film holders (18x24cm) are loaded up and the Brownie 127 pinhole conversion is waiting for its first outing, too. I can only hope I can find the time to shoot

Francois · « **Reply #73 on:** April 23, 2013, 02:42:59 PM »

Yesterday, I started working on my camera...
All the odd shaped parts are almost entirely finished cutting. Still a lot of work to do as it won't be anything remotely boxy!

I just hope there won't be any light leaks...

bump!

Also, I tested a cigar-box pinhole last night at a board meeting I had to attend... 2 hours long exposure on expired photo paper.
Marinated in caffenol...my usual process these days. Actually I'm using caffenol exclusively now.
It's all a blur now...

DonkeyDave · « **Reply #79 on:** April 28, 2013, 07:02:48 AM »

well the sun has been up for almost an hour in the UK, and my film is developing, are we going to have a separate thread for pinholes or stick them in next weekend's 'weekend thread'?

astrobeck · « **Reply #80 on:** April 28, 2013, 07:25:30 AM »

Dave, Leon had asked for some for the podcast, so you can send some that way.

But I also think it would be fine if you started a pinhole day photos thread so the rest of us can show what we did.
I know I'm looking forward to seeing how everyone's day went! It's just after midnight here, so I have some sleeping to do first!

4 paper negatives exposed. Wow, f/400 at ISO 3 makes for long exposure times!

Let's see if I can get any pleasing results as this is the first times with that camera and paper negatives.

Sandeha Lynch · « **Reply #86 on:** April 28, 2013, 04:17:19 PM »

It's the first time in years that I've actually made one on the day itself. But I had to stand in the rain for 60 seconds.

Ezzie · « **Reply #87 on:** April 28, 2013, 07:02:49 PM »

4 4x5 negs, and 8 6x9. However it was both bl..dy windy, and it rained. Not to mention it was below zero this morning. Since I´m a pedestrian these days, I cut the walk short. The weather got me stressed, so I think I managed to ruin at least one 4x5 neg, if not two Exposures ranging from 20s to 100s. Been a long weekend, so will not develop them tonight.

Moiz · « **Reply #88 on:** April 28, 2013, 09:48:58 PM »

Disaster! I have, hanging to dry, three perfectly black paper negatives. Not quite sure what went wrong, the autopsy will begin tomorrow. I'm gutted.

Francois · « **Reply #90 on:** April 28, 2013, 10:38:23 PM »

Because I wanted to make something unique and truly awesome, I actually ended-up making the pinhole camera from hell!
OK, short description and story: I wanted to try and make an ultra telephoto pinhole camera with never before seen features. I ended up using a large cardboard tube as the body. That meant an 1841mm focal length on 35mm film. Angle of view was a measly 1.34°... so I needed a special viewfinder which I crafted using some spring hinges and MDF. It worked just like on the old folders, only the target at the end of the tube was smaller than a 35mm frame. Tripod mount installed at the center of gravity. Rotating camera mount with Nikon bayonet made from PVC and MDF. Pinhole made from a soup can lid (probably the best pinhole making material I've come across). Magnetic neodymium pinhole holder for easy interchangeability. A pretty incredible sight.

First, how do you carry a six foot long tube? Not that it's heavy in any way but it's dang cumbersome.
For that focal length, the correct pinhole size gave me an f/923... super dark. In full sun, I had a 15 second exposure on 320 ISO.
Then, there's the vibrations. Just breathing next to the thing sent it shaking like crazy. My tripod head was always slipping because of the leverage.
Also, there was the viewfinder's precision which wasn't that great and simply got worse when I accidentally dropped the tube. The cardboard got ripped by the shear force put on the viewfinder. The epoxy held-up great, it's just the cardboard that didn't fare so well. So now, I was shooting using a found rubber band to hold it all in one piece, getting strange looks from everyone...

Morale of the story: super sized pinholes with super long focal length and small apertures are not a good idea.

Hopefully, this won't be a total fiasco and I'll have a few color shots worth showing.

But at least it was sunny and warm...

Moiz · « **Reply #91 on:** April 28, 2013, 10:41:53 PM »

Its the first thing I checked Diane when I came out of the darkroom but I couldn't see one. And I used and developed a pic with the same pinhole not three days ago. I think I just badly misjudged exposure :-(

Ok finally got there, here you go shot on the nice Ilford 4x5 (which only comes in one color) processed the Neg in my Jobo CPPA2 using the fuji hunt chemistry, scanned on the epson V750 and only spotted for dust otherwise its pretty much as scanned/shot.

Been saving this leaf for a while .

really good fun have reloaded the double dark's slides for some more !
