Original design introduced in 2013 – The RealitySoSubtle 6×17 is a dual pinhole/shutter curved film plane 6×17 panoramic pinhole camera that uses 120 film. The pinholes are located at the centre of a 70mm radius circle. Upgraded in 2024 to include 3rd central pinhole, filter holder and improved ergonomics (image characteristics unchanged).

Curved film plane?
The film plane is curved to ensure even exposure across the negative, not possible with a flat film plane with such an extreme wide angle view (141°). Compare to a flat film plane camera where the distance of the pinhole to film distance increases towards the frame edges causing darkening in the corners of the resulting photos. A side-effect of the curved film plane is that it results in a curved horizon in your photos unless the photo is taken with the camera level. 
Which pinhole to use?
As mentioned above, if you want to have a straight (not curved) horizon in your photo then you need to have the camera level. A consequence of having the camera level,and a pinhole in the center would mean the horizon dead center of every photo. That is why this camera has a pinhole above and below center. It’s simply a matter of making better composed photos. You can chose to place the horizon on either the upper third (use the lower pinhole) or the lower third (use the upper pinhole). Obviously using the central pinhole puts the horizon in the centre.
Size/Weight
The camera weighs 0.85kg. Length x height x depth = 212 x 89 x 89mm. (Dimensions of ‘box’).
