Since I've had trouble finding such comparisons of my own, I thought
I'd post these. I shot them both within a minute of each other on
Saturday morning (around 9am) at Sandy Stream Pond, Baxter State Park,
ME.

Note: I shoot RVP50 at ISO 40, which accounts for it being somewhat
more exposed than the 100 sample. I shot the RVP100 at ISO 100.

Both shot on a Cambo 4x5, Rodenstock Sironar-N 150mm, Singh-Ray warming
polarizer.
