Welcome to Big Mountain Photography!
Today, I present my first set of pinhole camera images using Kodak Porta 400 120-film. If I had to guess, many people have not heard nor understand the use of pinhole cameras.
Note: I’ve stopped posting individual images on Facebook as I’ve chosen to share not just an image, rather a story with a gallery of images. We’d appreciate your patronage so please FOLLOW along.

Let me get the semi-technical questions out of the way. Here’s the scoop:
RealitySoSubtle 6×17 Medium Format 120 Film Pinhole Camera
– The “Pinhole” is 300 microns (0.300mm) at f/233, 70mm focal length with a curved film plane to avoid corner vignetting and field of view 144deg x 41deg.
– I use an iPhone app, “Pinhole Assist” to Spot Meter (~20deg) plus includes film reciprocity considerations in the calculated exposure time in EVs.
– You get 4 Exposures per a roll of 120 MF film with the film numbers centered in the rear, red viewfinder at 2 ( 1 and 3 on the sides), then 5 (4 and 6 on the sides). 8 and lastly 11.
So how do you load the film, see video: LOAD
So how do you take exposures, see video: EXPOSE
So how do you process the scans: TWO-OPTIONS
#1: Buy yourself a professional, home scanner, i.e. Epson v850 to scan the entire 6×17 negative either dry or wet. This my medium term solution.
#2: Use a local lab with a Frontier or Noritsu by theFINDLab roll scanner yet there is a limit of 6×12 for a single image. This is my current solution, not optimal given I must then stitch the images and correct for exposure difference in Photoshop.
Problems So Far Encountered
Photoshop Processing Approach with 2 Exposures
Eventually, I will secure an Epson flatbed scanner to do full 6×17 negative scans plus 6×6 / 6×7 negatives from my Fuji GF670 medium format camera. The use of SilverFast and Digital ICE software to combat the removal of “dust” on color negatives is imperative.
