Thanks for the information Baxter. I had thought about the center filter, but I'm not sure that my landscapes would include enough of open sky ( I often shoot in "old Florida woods" which are rather dense) which would make the center filter necessary. Good suggestion about the Fresnel screen, but the added expense is something I might want to avoid if possible.
Speaking of added expense: Is anyone using one of the Ebony "viewers"? Using one would appear to make the entire process easier.....out with the camera with lens already attached, onto the tripod, open viewer...off to the races.
Speaking of speed....I just returned from our local state park and a photo hike down a some what isolated dirt road. Setting up the Canham 4x5 is really not a big deal....relatively quick....I mean, not Leica quick, but about 5 minutes from unfolding to composing. What IS heavy is that Ries tripod with their special tilt head...
