Bulldog 10x8 Pinhole

[littlejim]

Hi! I've acquired a 10x8 Bulldog with its original pinhole but no instructions on what focal length to set or the effective aperture. I checked the Bulldog website but there's no info posted. Any help would be greatly appreciated!

For a first guess, try f/295, or one minute in bright sunlight (film) or 5 minutes (paper). Rinse, lather, repeat ...

And while you're waiting, check out f295.org , the pinhole camera forum.
