Sydney Gerber, "Finally in the Sun"
Maasbracht, Limburg, Netherlands
Maasbracht, Limburg, Netherlands
"This is a photo, I took of myself using a pinhole camera I designed and 3D printed myself, sitting outside our home. Luckily it was a sunny day. The 3D files can be downloaded for this camera. Search: SGR-5x7-0.3. I also includes a document taking you through the entire design process."
"It has a 0.3mm aperture and a 67mm focal length, using 5×7 inch B&W photo paper. I assumed a paper speed of ISO 3 and metered at f/128. The metered exposure time was 60 seconds. The corrected exposure time was therefore: 60s×3.04 = 182.4s, approximately 3 min. I then developed it in in Caffenol-CM."
