6x24 pinhole?

[gb hill]

Saw this browsing thru the Filmwasters forum last nite. Great job Ezzie.

 

[Ezzie]

Thanks.

Funny thing happened when I took the river landscape picture. A friend drove up, stopped and wound down the window. His first comment was, wow that is an advanced camera! I was forced to reply that it was in fact the exact opposite. The simplest form of camera there is. He was impressed none the less 😉

Ezzie, I've never been into pinhole photography much, I always thought it just meant fuzzy photos. But what striking photos you've made with it (and a beautiful camera too), really impressive stuff.

Cheers

Thanks Garry

Well, pinholes will never be sharp. The pinhole itself is important to get as circular as possible, and to minimise diffraction, punched through a thin as possible material (metal foil etc). But still, the CoC will be limited by the size of the pinhole. So bigger film formats will be of a premium, as you need not enlarge them as much. Makes for sharper pictures, in a sense. I have four pinhole cameras, and the smallest being 6x6, smaller than that I wouldn't go (personally), the biggest 4x5.

Portra 400 and an ND8 filter. 2, 6 and 8 minute exposures. I used a reciprocity table posted on Large Format Photography forum, and for a first I am quite happy. Developed at home with the Tetanal kit.

Thanks, I'll be crossing my fingers

Eirik,
Very impressed with your photos, well done!
Are you scanning the negatives or the prints? Could you elaborate a little on that part of your process, please?
I am about half way through my own build and this is starting to concern me: I don't process at home but do have a good mail order lab. That doesn't scan bigger than 6 x 9...my camera will be a nominal 6x12--the actual negs should be about 55mm x 115mm--so I either need to buy a scanner and learn to use it or find another lab...
Thanks!
Rob

Hello Rob

The short story is I scan the nagatives. My Epson v500 takes up 6x12 in the standard 120 film holder. For 6x17 and 6x24 I tape these to the scanner bed. The latter only just fits. The light opening for film on this scanner is most likely 70mm x 250mm or there about. In fact these scans often come out as sharp or sharper than frames scanned in the holder. Most likely my specimen focuses closer to the glass bed, than the holder.

I have had a longstanding intention of building a darkroom. But due to size constraints, will not equip it with anything bigger than a 4x5 enlarger (capable of 6x12, just). So for bigger formats I might continue scanning, then digital print a new smaller negative and use that in the enlarger. We'll see.

Only one from the latest roll, the film got mangled in the camera.

Tri-X, expired some 10 years ago. Tetenal Ultrafin 1:10 9mins.

Ezzie,

Excellent camera, excellent photos! Very cool stuff.

You're inspiring me to pull out my 66/6 Pinhole Instant Film camera and charge it up... 🙂

Thanks for posting this wonderful contraption.

Here is my New 6X24 Pinhole Curve Camera

If you want more information about it, please send me a mail at dviard dot wanadoo.fr

Is the pinhole placed at the radius of the curve?

I forgot to check back until today 🙁. These shots are really nice.

Thank you Godfrey and Gary.

@Zuiko85: My film plane is not completely semicircular, due to constraints in the box I chose to build it out of. But ideally it should be. In which case the pinhole is at the radius of the curve.

@Landruen: Very nice. Great fun to make your own camera, as simple as can be, yet get results that are simply quite amazing. Love the small vid you have made.
