This has confused me. What's the purpose of the ASA dial other than to tell the camera how the TTL light metre should read? I've checked the Beaulieu manual and it says:
Caution:For outdoor filming with "indoor" type film, the "daylight speed" should be set opposite the green dot. Example:For Kodachrome 11 type A film, set 25 ASA for outdoor filming (daylight).
Does this mean the manual is incorrect?
I've exposed 64T as 40ASA (as instructed) in daylight with 85 filter and results were fine.
