Original design introduced in 2014 – The RealitySoSubtle 4×5 is an ultra-wide angle flat plane tri-pinhole camera with central and rise pinholes/shutters on both horizontal and vertical orientations – uses 4×5 sheet film or paper.
0.3mm0.2mm precision laser drilled pinholes, 38mm35mm focal length. Aperture = f/127f/175 Pinhole material thickness = 50 microns (.002″).
- 3 separate pinholes and independant magnetic shutters. One central and 2 ‘rise’ pinholes for fun perspective effects (both offset 31mm from centre).
- Accurate bubble levels for both portrait and landscape orientations.
- Tripod mounts for both portrait and landscape orientations.
- Accurate sight lines engraved into the wood for ease of composition.
Built to last
The main body of the camera is made from 15mm thick solid oak with the sides joined neatly using double rabbet joints. The front face sits in a recess in the oak body and is made from a 4mm thick wood effect vinyl tile – durable and scratch resistant. The shutter panels and pinhole board are made from 3mm high impact polystyrene. The shutter pulls and locking beam fasteners are stainless steel. The wood finish is a satin varnish. The film holders (standard 4×5″ film double dark-slide holders) are held securely to the camera by a simple yet efficient profiled oak locking beam which applies pressure to the film holder via 2 knurled stainless steel thumb-wheels. (The operation of the back is illustrated in the video below).
The ‘Rise’ pinholes
Using either of the rise pinholes adds two effects to your image:
- There is a straightening effect on diverging verticals – this is especially useful for shooting buildings
- The horizon is shifted – this is nice if you are shooting with the camera level on the ground, you can achieve a more pleasing compostion having more ‘sky’ than ‘land’.
You can see examples of these effects in the gallery below. Note: The pinholes are set in large 18mm brass discs and are removable should you want to replace them. The board to which the pinholes are mounted can also be detached (via 3 nuts inside the camera) to allow access to the moving shutter panels. Cleaning the shutter panels might be required if, for example, the camera took a tumble on a sandy beach.

Other film backs?
By using longer bolts for the rear locking beam various backs of different dpeths can be accomodated. Here’s a 4×5 with a Fuji instant back fitted.. (Email for details if you want to use a different film back.)
