Hi, I am planning to shoot pictures with some slow films during a trip in Istambul (Turquia). This will be the first time I will shoot films again after 6/7 years of digital capture. I bought a Zorki-C on eBay and after much browsing on the net, I decided to use Efke KB 25 and Adox CMS 20. (I know quite well the look of the first one and I like it very much; I would like to try the other one also). I will ask some questions concerning the Efke KB 25 in a separate thread.

For the Adox CMS 20, I would like to know what you think of the two following chart (the EV value at the left edge is the usual EV100 value of the scene to be captured, see http://en.wikipedia.org/wiki/Exposure_value).
It looks like Adox CMS 20 isn't "true ISO 20" film; I actually like the look of the pictures on the following thread: http://www.rangefinderforum.com/foru...d.php?t=118206 (shot with ISO set to 12).
If I look at my chart for ISO 12,5 (I hope the computation is right) and at the meaning of the exposure values, I think I will be able to shoot mostly in the following conditions:
Typical scene in full or slightly hazy sunlight (distinct shadows) 15
Typical scene in hazy sunlight (soft shadows) 14
Typical scene, cloudy bright (no shadows) 13
Typical scene, heavy overcast 12
Areas in open shade, clear sunlight 12
(I discarded EV=16 because I am not sure I will have such a scene in Istambul).

Now, I want to have a speed greater than 1/50, and according to my chart, I have to discard EV=12. Thus I should be able to shoot in the following conditions:
Typical scene in full or slightly hazy sunlight (distinct shadows) 15
Typical scene in hazy sunlight (soft shadows) 14
Typical scene, cloudy bright (no shadows) 13

Can you tell me if this is right? Can you also tell me if I can get something good by shooting Adox CMS 20 with aperture between f3.5 and f5.6 and speed between 1/50 and 1/100?
