would like to know method of determing proper exposure
when using grad nd filter 2 stop soft edge sing-ray.
I was told to take reading on foreground then put filter on.
also told to just put filter on and the auto exposure will
make adjustment for filter. I have an
f5 and shoot in aperature priority 99% of the time. I have
come to trust in the matrix metering system for almost any
situation. thanks jay obrien

Congratulations on your winning of the August Monthly Nikonians Photo Contest.
It is my understanding that the RGB meter of the F5 will take care of everything and anything, but let us hear from the actual F5 users in these Discussions.
Have a great time

The F5 meter will take care of approximately 95% of all shooting conditions; however, a ND filter is great when you have an extreme backlighting on one half of the photo. I have used a grad ND filter a few times with the F5 with great results. It does prevent any chance of extreme backlighting in half the frame from messing up the meter's reading.
Possibly, someone with more experience with the grad filter can give us both some info.
(I do know if you use a color grad, color filter or enhancing filter, use center or spot metering. The color filter can mess up the F5's RGB meter.)
Just to clarify the 95% figure from above. I would guess my F100 is correct 80% of the time. The F100 is easily confused with backlighting or reflections off water; whereas, the F5 tends to disregard small areas of flare from water or small areas of backlighting such as brigh sky through trees. The F100 is still better than my N90s was, of course it has a better meter with more segments to help level the playing field. This is from my experience shooting both cameras. I do have more experience with the F5 than with the F100.

Let me jump in with both feet. Seeing that I'm starting to feel better.
I would recommend not relying on built-in meters with color or graduated filters attached. I prefer to meter the scene with a hand held spot meter and then attach the filter and some simple exposure computations.
But with that said...
The purpose of the graduated ND filter is to decrease the latitude of exposure of a scene in order to capture details in the highlights and shadows. Right?
So, I would say that "in theory" the built-in reflective meter would work fine in selecting an appropiate exposure. Also, I believe it would be more accurate to meter with the filter in place, if still talking about the grad ND.
But, even with the F5 RGB meter, I would not use the same theory with colored filters.
Hope it helps
