The first camera that I built
is a
large format , 5 x 7 inch , monorail camera (based on Cambo 4 x 5 inch)
which
can be used in panorama mode. I designed special rail to fit 5 x 7
inch
film holder to snugly fit cut 120 size film. Film is cut in dark room
and film inserted in holder. I made special cutting board for this,
I also can cut 8 x 10 inch fit to 5 x 7 inch format, 5 x 7 film is hard
to obtain ( find ). With film holder fit with rail I can take 4 images
6 x 17 cm. To do this I made
new mask for
G/G
( link to PDF file G_G_5X7A_www.pdf file size 8Kb ) to help me focus
first
to top section of holder. I close lens and remove the dark slide and
insert
special cut dark slide to mask bottom of film holder, fire the shutter
with a cable release. Remove special (half dark slide) and insert
normal
dark slide turn film holder around and continue as before. Next is to
focus on bottom of film holder, then I close lens and remove the dark
slide and insert special cut dark slide to mask top of film holder,
fire
the shutter with a cable release. Remove special ( half dark slide )
and
insert normal dark slide turn film holder around and continue as
before.
More information's, images and how to develop strips of film you will
fined
in PDF file 5x7to617.pdf .( I am working on it and will publish on www
later) ( file size 800Kb include new mask for G/G)

My second camera is based on
maximizing use of 120 roll film. My calculation
give me 4 images and 4 mm spaces. Image size is 56 x 195 mm. Me desire
was to design film holder for this image size. I was told this format
its
not standard and development laboratory will cut to my images. This
discouragement didn't stop my desire to maximize use of the film.
Finally, I made two film holders and ground glass. To fit film holders
to this
adapted Cambo 4 x 5 SC, I made back standard adapter plate. This
allowed me to take even wider images. With longer monorail
and bellows, lens from 72 mm to 450 mm can
be used. I use 72 mm SUPER-ANGULON XL and 90mm
SUPER-ANGULON
XL. Components are made from
aluminium (6061) and black satin anodized. I machined them myself.

Back made from 6061 Aluminium,
polished and satin anodized. Other materials used Stainless steel,
Brass, Bronze. I have new improved design for 6 x 20 back.
Hand ground Ground glass (grid size
10mm).
My third camera its "point and shut" based on 6 x 20 film
holders. Again I made back plate to fit 6 x 20 film holders and G/G.
Front frame hold frame which accept Cambo lens board. Back frame have
tripod mount and front can be moved for focusing.

components - not yet anodized.
In year 2000 I began designing and building my 300° &
360° panoramic camera. Because of financial difficulties and I was
site track to build others projects, work progress slowly. I will
continue
work on this camera.

camera.

Middle front:
300° film
plane for 80 mm f2.8 CZJ Biometar MC lens.
Far right: 360° film
plane for 50 mm f4
CZJ
Flektogon MC lens.
Lens will be mounted on body where is blue dye. Image size will be for
80mm lens (for
300°) 418mm and for 50mm lens (for 360°) 314mm.
The frustration is that I have even more designs for panorama cameras
and film holders, no time and money to build them. The results though
can
be improved greatly.
Designs in progress:
- 6 x 13 film holder for new Panoramic camera ( 5 images on film)
- 6 x 12 film holder for 4x5 camera (under G/G).
- 6 x 17 film holder for 5x7 camera (under G/G).
Special Interests:
- Pinhole photography, BW paper as negative and contact printing.
Other cameras I use:
5 x 7 Cambo SC with reduction for 4 x 5. Pentagon six, 6 x
6 ( 2 1/4 x 2 1/4 ).

4x5 reduction back.
