Speed Graphic with 203 Ektar in situ, a black tee shirt & five holders in a Jansport Equinox daypack with a Tiltall strapped on board(if I want the luxury of a tripod) and some Wratten series something or other filters.
Gowland aerial focused for infinity with a 300 M Nikkor and one (1) film holder riding inside and a lightmeter 'round my neck (with only two shots I want to be certain of the exposure) a Tiltall Junior and seperate cable release (if I need a tripod) A few filters borrowed from my Nikon SLR. If I need more than one filmholder I can fit five or maybe six in the Jansport Equinox
You're joking, right?
Camera, with 240 G Claron reversed and folded inside carried in one hand, Ries tripod in the other. Light meter & loupe around the neck, extra film holders, filters & dark cloth in a Jansport Equinox(unless I either need a lot of them or maybe one free hand for support, then the 'dorff and film holders ride in GI surplus 5 gallon water cooler with a shoulder strap, but man that gets heavy!)
