Silverlog Pinhole

Design and calculate pinhole cameras. Find the optimal pinhole diameter, f-stop and exposure for any focal length and film format.

Silverlog Pinhole calculates the optimal pinhole diameter, effective f-stop and exposure adjustments for pinhole camera photography.

HOW IT WORKS Enter your focal length (the distance from pinhole to film plane) and the app calculates the optimal pinhole diameter for the sharpest possible image, the effective f-stop, and the exposure compensation needed compared to a conventional camera.

FEATURES • Optimal pinhole diameter calculation • Effective f-stop calculation • Exposure compensation from base metered reading • Multiple film/sensor format support • Works offline — no internet connection needed • Clean, focused interface • Dark mode support

USEFUL FOR • Building DIY pinhole cameras • Converting existing cameras to pinhole • Calculating exposures for pinhole photography • Understanding the relationship between pinhole size and image quality • Educational exploration of camera fundamentals
