Exposing Ektar 100, Provia 400 and Efke 25/50
I shoot landscapes and some travel/street scenes using Canon FD 35mm (manual focus) cameras with manual exposure. Film is scanned on a Nikon CoolScan V. I've been changing how I meter from using the built-in meters to a Sekonic 558, generally spot metering, at least for the landscapes.
This is my simplified approach for most daylight scenes (using grads as necessary on the slides):
- With Velvia, I typically meter the highlight where I desire detail and then expose at +1 to +1.5. Shadow detail is pretty good down to about -2.5.
- With Provia 100, I do the same but expose at +1.5-2. Shadow detail is pretty good down to about -3.
- With Acros or 400H, I meter the shadows and expose -2-3 and let the highlights go where they will.
I haven't had time to experiment with the Ektar 100, Provia 400 or Efke 25/50 and I'm going to be shooting some while I travel in Latin America (I'm on the road now).
- From reading about the Ektar, I think I would get good results treating it like the slides but exposing at +3 to 4 over the metered highlight. This sounds extreme but folks seem to describe good luck with Ektar's range.
- Can I treat Provia 400x like Provia 100 (aside from changing ISO on the meter)? I've seen some vague references to Provia 400x having extended range to highlights.
- I have the impression that I should treat Efke 25/50 more delicately than Acros after reading some references to it's range being somewhat contracted. Recommendations?
Datasheets (I'm still trying to figure out how to read & interpret datasheets for my style of exposure):
