Freak of Stature

I've modded an old Ernemann bellows camera made for an obsolete film format. It can now make 10,5 x 6,5cm panorama images on standard middle format 120-film.
All geared up and ready to go!
It began with the purchase of a roll film back for my camera, which is of the obsolete but common large format standard which exposes on 9x12 cm film sheets, glass plates or - lucky me - the odd roll film.
Here you can see the modded original wooden take-up spool and the modded inserts for the feeding spool.
What I first did was trying to lessen the width of the take-up spool. Otherwise the 120 film would not wind up in the middle but go from side to side and the images would all have leaning horizons.
Loading the film. It goes from where the arrows are to the wooden take-up spool. The whole spool/winding insert also acts as a pressure plate.
I then found a way to make inserts which would hold the film feeding spool in position. Some rather stiff packing foam "drilled" through to accomodate for wooden pegs which were then glued in position made for stable inserts.
This is the small viewfinder set next to the lens. The exposed image is what is visible between the blue marker lines, as to my approximation.
I managed to load the camera with a roll of 400 ASA Fomapan. The widest aperture is 11 and the shutter presents the choice of B(ulb), 1/25th, 1/50th and 1/100th, so there are challenges. Tripod mount screw size also...

According to my crude trial I can fit 6 exposures on a roll of 120 film. 5 half rotations of the handle are necessary to get to the next exposure. When the film is first loaded 17,5 half rotations are needed to reach the position of the first exposure.

Update:
The first trial photograph:
It's not very interesting, but focus is there, at 2 meters which is minimum focus distance. This was 3 seconds at f11.
I'll fill you in on further adventures!

You will find 9x12 film plates in my camera shop getOurBooks at Etsy!
I also have a group on Facebook called Analog Photography & Camera Modding and DIY.

Chaika Leica

Well, here's a Chaika 2M that I bought from Alex Helios via Instagram.  It's a great full manual viewfinder half-frame camera. The wheel on the top is for shutter time selection, from B to 1/30th to 1/250th of a second. The square button on the front right of the camera is the release/exposure. The lens mounted on the camera in the picture is not the original Industar-69. The Chaika is a rare model compact camera since the prime lens is detachable. What is more is that it has M39 screw mount. But - like with the Paxette M39 system - you can't get focus with a lens from another M39 system. Unless you adapt the lens or - in this case - the camera (mount)! The Chaika mount is easily detached from the body by loosening four screws. If I want to mount the Leica thread mount M39 (LTM) lenses on the Chaika - which is my goal with this mod - I have to add 1.3mm to the mount. That is what is needed to change the camera's flange focal distance (FFD) from Chaika system to L

Redscale Film in a Halina 35X

  I made a Kodak Ultramax 400 ASA colour film into redscale last summer. I exposed it at 25 to 100 ASA. These are some of the photos. Visit my  Etsy shop  for cameras and related stuff,  the  facebook group  on modding lenses and cameras or my Instagram accounts ourbooksmalmo or flashknappen .

Stare Crazy - a Budget Wide-Angle Lens Solution for my Olympus Pen F

I fitted a wide-angle screw-on lens for a Konica 8 Zoom super-8 camera on my Steinheil Cassarit 45 mm and my Voigtlander Color-Lanthar 42 mm. I got WIDE on my half-frame camera!   It wasn't pretty, but it did the job for sure! I've been racking my brains for years trying to come up with a low budget wide-angle solution for the Pen F, which is the SLR I use the most. I got more than I could wish for because of all the character the lens contributes to photos! The film is a Fuji Ultramax 400 which I haven't colour corrected in any way. I increased contrast. The rest is the work of the scanning program. I didn't find the Ghostbusters' garage. It's my brother's!
