While reading through Gevalia's recent thread on film options for a slot canyon trip http://www.largeformatphotography.info/forum/showthread.php?t=39872&highlight=slot+canyons a thought came drifting up from the deep, dark, cobweb-filled corners of my brain:rolleyes: : What about flash or pre-exposing color slide films on large format? Are there any chrome shooters here that use pre-exposure (shooting an out-of-focus, evenly-lit gray card at 2 to 2 1/2 stops under to put down a little light on the film, then recomposing and shooting the subject) to bring up detail in shadows?
I had experimented briefly with this a few years ago with 35mm before I switched to a digital darkroom, but was a bit dissapointed with saturation, IIRC. With Photoshop, saturation would no longer be an issue.
While this process could be a bit awkward with large format in the field, one could easily do pre-exposure on a few sheets of film earlier in a more controlled environment - especially if using Quickloads - before heading into the field. Simply pre-expose the film at home, note it on the Quickload label area, then use those sheets as the need arises.
Any thoughts? Do Provia and Velvia respond well to this process?
