Confused with EV metering. 
Jorge Gasteazoro  17:51 13 Jan 04 
Ok, I just got my plotter and expo/dev programs today (woohooo) so playing with the palm program and exposures using the incident system I got two different EV values for ASA 400 and ASA 125. The values made sense, for the 400 film it was 6.2 EV, for the 100 film it was 4.2. EV(have both ISO numbers on my Sekonic 508).

Now I suppose that when I export my film data from the plotter the program will take into account this. But, for example if I am using TMY at 400, which EV value should I use, the one for ISO 100 or the one for ISO 400?

Ah hell, never mind......I just though that all I care about is SBR and it would be the same for either metering speed....sorry.....

BTW, Phil, better get some rest, I am sure I will have a lot of questions..
