Photographic Pinhole


SKU: SS-3/8-PHOTO Category:


Photographic Pinholes deliver premium pinhole photographs by using a thin steel substrate, and ultra-precise laser drilling.

Each pinhole is inspected in production, post-production, and final inspected to triple-insure the quality and precision of each piece.

Your Photo Pinhole comes mounted to an 18mm black anodized Aluminum mounting disc.

Formula for Calculating f-stop

f = fl / d

f = aperture

fl = focal length (distance from pinhole to film)

d = pinhole diameter
