Proving Sunny 16

[lex_jenkins]

The cheat sheet on the back of my Rollei confirms that "Sunny f/11" seems to have been the recommendation back then.

I've got one of those wheels. Check the different films. Mine shows different results for different films. Some are F/11 some are F/16. My thought it was related to the light the film was sensitive to. If I remember right the colour slide film was F/16 while the F/11 was some B&W films.

You are correct. I did not use any color film then so I did not bother to check the exposure index for them.

 

For those who were not active in photography in the 1950,s the following exposure indexes applied(note this was for daylight as most film had different indexes for tungsten}:

Soper-X...100, Plus-X...50, Verichrome...64, Panatomic-X...32, Kodacolor...23, Kodachrome...10, Ektachrome...8. Verichrome was an ortho film, Verichrome Pan came later.

If you are wanting to prove "sunny 16" and be really accurate,you need to have a perfectly clear mid-day sky(not even high altitude haze).I won't go into everything after that,but without the clear sky there's no use doing all the rest...Jim
