No guts no glory. I agree with the 8 x 10. I myself would be carrying the large film format you can. Cut down on fancy lens Carry more film. A good wide angle, a medium tele and a compact zoom. Also the most stable tripod you can handle. My kit for an average shoot is three bags. 1 film, 2 light meter and other gear, 3 tripod. Oh then the camera.
What grain............................................. ...............
Oh sorry, I forgot you don't shoot Large Format
Large format Pat.
“The photographer must determine how he wants the finished print to look before he exposes the negative.
Before releasing the shutter, he must seek 'the flame of recognition,' a sense that the picture would reveal
the greater mystery of things...more clearly than the eyes see." ~Edward Weston, 1922.
I agree that backpacking/hiking and photography are wonderful companions. However, the type and amount of gear that I take camping depends upon where I am going, how far I am walking, who I am going with, and how much opportunity there will be for contemplative photography. The things that often don't mix well with carrying bulky gear are companions who are not photographers and a fast pace.
Each to his own, but I would almost never take more than one camera with me on a serious hike. It might be 35mm, MF or LF, but I personally find it liberating to remove a few choices. That's part of the reason I go walking in the first place - to get back to some simplicity. Taking just a good rangefinder and a light tripod can be a very nice way to travel in the bush.
