Sunny f16 Rule
Jul 21, 2017 20:50:42 #
Hi all the sunny f16 rule was used when some film cameras did not have built in light meters. The rule states that on bright sunny days set the lens aperture at f16 and the shutter speed the same as the films ASA(ISO). For this example a films ISO could not be changed mid roll. An example triX ISO 400 f16@1/400 for a bright sunny day.

Sunny 16 has been there since the beginning of photography. It used to be printed inside Kodak film boxes, those boxes that once we got the film out we threw away.
It certainly works as a base exposure. Other apertures can be used as long as reciprocity is kept.
Sunny 16 is very useful in countries with lots of sunshine like here in Southern USA. I should say it only works for front lighted subjects 2 hours after sunrise till 2 hours before sunset.

Last I heard TRI X 400 is a B&W film.
blue-ultra yes sir! I shot and developed many rolls. I even bought 100foot rolls so I could roll my own to save a few bucks.
Thank you for looking and commenting. Dane004

With DSLRs, this is a great foundation to build exposure.
rgrenaderphoto correct sir!

To me "roll your own" has nothing to do with film

I think there is still part of a 100 foot roll of Tri-X in the bulk loader my dusty basement darkroom. I haven't touched film or developer for at least a dozen years.

All but perhaps some of the youngest members are aware of Ansel Adams's image, "Moonrise, Hernandez, New Mexico" and the story behind it. Google the image and its story. There are several accounts around how that image came to be, but here is the most accepted version in the words of Mr. Adams from his book "Examples: The Making of 40 Photographs:"
"I could not find my Weston exposure meter! The situation was desperate: the low sun was trailing the edge of clouds in the west, and shadow would soon dim the white crosses ... I suddenly realized that I knew the luminance of the Moon — 250 cd/ft2. Using the Exposure Formula, I placed this value on Zone VII ... Realizing as I released the shutter that I had an unusual photograph which deserved a duplicate negative, I quickly reversed the film holder, but as I pulled the darkslide, the sunlight passed from the white crosses; I was a few seconds too late! The lone negative suddenly became precious."
The intensity of sunlight on the full moon is the same as sunlight on earth at noon. So his words of explanation are essentially saying that he used the sunny 16 rule to capture this famous image.
