Exposure with extended sunny 16 rule

Too many words already said about the sunny 16 rule. But, I’ve discovered an old user manual which was included in each box with ORWO CHROM UT21, a 100 ISO color reversal film made by the ORWO film factory in East Germany. I put it between the pages of a book on photography techniques when I was young and came across it years later.

I really like this table of weather and shooting conditions. But since it has been made especially for reversal films, negative films may become overexposed if you strictly follow its guidelines.

It reminds me of my own “Extended sunny 16 rule” which I follow when I have no exposure meter with me. But still I prefer the matrix of shooting conditions to the classic sunny 16 rule.

T, sec = 1/ISO Sunny Hazy Cloudy Overcast Heavy overcast
Snow, sand or sea F22 F16 F11 F8 F5.6
Direct light F16 F11 F8 F5.6 F4
Open shade F11 F8 F5.6 F4 F2.8

    You do not use Pentax 67 metering?

    • No, it’s too heavy for me, especially when composing the vertical shot and I sold it. Anyway, the latest model of the metering prism is very accurate. Usually, I use Polaris flash meter.

        I got what you mean from pictures. I think I will try to use it first. I bought quite a lot things without knowledge, quite crazy… But I believe I will have a lot of fun with it. Are thouse cheap new meters from ebay usefull, do you know? Thanks! By the way, I like your stories to each portrait, but there is no possibility to comment it there, so I do it here. 🙂

        • I bought my Polaris flash meter about 20 years ago and still use it because I already have it. But you may at first install software lightmeter on your smartphone or tablet. It gives good results. Anyway, you should test it, especially with your shooting style to understand do you need to add exposure compensation or not. And, when you gain some experience with it you may decide to buy cheap “external” meter like Sekonic or Gossen. Maybe you won’t need it.

        • Thank you very much for the feedback about stories. It is really important for me to know!
