So here I am, making my first foray into 4x5. I purchased a used Tachihara, and have a couple lens/shutter combinations. The lens that came with the camera is a Schneider-Kreuznach Symmar 210mm with a Synchro Compur shutter The second lens is a brand new Schneider-Kreuznach Super Angulon 58mm mounted on a Copal 0. I noticed no light leaks in the bellows, and use a Sekonic L-758 DR for all exposures. I have a decade or so of what I call "cognizant" photographic experience, but I've been looking through viewfinders for three decades. I took my new Tachihara out for a test drive, using Fujichrome RDP-III, 100 ISO transparency film. I took 16 shots, all properly metered for the light and ISO, and sent them off to Iris Photo and Digital for processing (eventually, I'd like to get into doing my own, but I want to limit my universe of possible mistakes for the moment). Every negative came out very red and very dark. I did the same thing again with the last four sheets from the box. I shot one exposure through each lens/shutter at a "proper" exposure, and one exposure through each lens/shutter, intentionally overexposing by about 2 stops. Again, red and dark. Any thoughts? Is this the kind of thing you see with a user error (e.g. loading the film backwards/emulsion facing the wrong way), or is this something else? Is it heat damage (the film sat out for about fifteen minutes after the UPS guy dropped it off)? I would have thought that with transparency film, SOME color would have come through, but no luck. Everything looks rather like a color negative (and yes, I made sure that it was transparency, not negative film). Any thoughts would be appreciated. Thanks!
