Re: World's largest pinhole camera

Jan,

According to Mr. Pinhole Calculator, if these people want to use a
focal length of 80 feet (!), the optimal pinhole diameter should be a mere
6.58mm, yielding an effective F/stop of F:3706 !! That is very slow!

Then, imagine coating a piece of linen 25x100 feet with 20 gallons of Liquid
Light. Not to mention processing. Hmmm.

Best,

Guy
