My experience was that adding up the areas of the multiple pinholes, dividing that into the area of an f22 aperture at the pinhole-film distance being used, and multiplying the metered f22 time by the product of the division works fine. ----- Original Message ----- From: Temi <t...@temioriginals.com> To: <pinhole-discussion@p at ???????> Cc: Temi <t...@temioriginals.com> Sent: Sunday, March 25, 2001 4:00 AM Subject: [pinhole-discussion] Multiple Pinholes
