Today's project entry is the first 4x5 pinhole shot. These are the ruins of blast furnace building # 8 at Lockridge Furnace in Alburtis, Pennsylvania. The Furnace opened in 1868 during the peak of the anthracite iron industry and operated until shortly after World War One. I'm using a hand made pinhole camera of wood and brass construction, more of a proof of concept at this point rather than a finished product. My plans are to perfect the design then make it look good. Eventually I'd like to make a 4x10 pinhole design for shooting X-Ray film in half sheets for panoramic shots. For those unfamiliar with pinhole photography, basically it utilizes a simple box that has a very, very tiny hole on one end and the film on the opposite end. When the shutter or latch is opened over the hole, light streams into the box and records the image on the film. Because the hole is so narrow (F225 aperture on this model) it gives an almost infinite depth of field making everything in focus front to back while at the same time making things appear soft and dreamy. It's photography at it's simplest form.
Camera: 4x5 wooden and brass pinhole camera. 0.4mm diameter laser cut pinhole, 90mm focal length giving F225 aperture.
Lens: None. LOL
Film: Arista EDU 100 Ultra 100 ISO B&W Negative Film (Re-branded Fomapan), shot at ISO 64.
Exposure: 9 seconds. Metered and timed with Pinhole Assist app on iPhone.
Development: Self Developed in Kodak Xtol 1+2 dilution in Paterson Universal Tank using the Taco Method. 13 minutes @ 20 degrees Celsius. Tap water stop bath. Ilford Rapid Fixer. Photo-Flo rinse.
Scanning: Negative scanned with Epson V600 in two scans and merged back together in PhotoShop since the V600 doesn't natively support 4x5 scans in one pass.
