Filter exposure compensation

Pretty happy with these. 50/2 'cron, 5.6 250, yellow filter at 2 stops. Very grey day, late in the day, rain.....

thanks for the help

Thought I might add something that will speed up using the Twinmate with your M4-P in the field without having to remember to open up one stop every time you take a reading.

I use a Fuji GW670iii with a yellow filter, factor 2. I just set the iso dial on my Twinmate one notch slower than the ISO of the film I'm using. This works at all film speeds and I've tested the meter's readings against my M6 classic 2/50, that's equipped with an identical yellow filter, at all ISO settings.

Easy.

Exactly what i am doing....after fiddling a bit with the math in my head

So just to be absolutely sure as this is something I have been toying with.... A camera loaded with say Tri X rated at 400 with a yellow filter (factor 2) would 'lose' a stop of light. When using an external meter this would need to be set at 200asa and not 400asa...yes? Conversely, if one wanted to maintain the the speed of the film you could push it to 800asa and set the handheld at 400. Or have I got it utterly wrong?

Your help/comments appreciated.
