    Goldie, 9x12 Avus type cameras seem to be extremely common in Europe (plenty on ebay) and they were sold under a variety of names Zeiss, Rodenstock, Voightlander, Ermann, Goerz, Ensign, Glunz, Orionwerk, Suter, Nelson, Welta, Watson etc and even a French un-named model. Essentially all these cameras are very similar, built from common parts and the major significant difference is the quality of the shutter and lens. There was not one standard fitting for the 9x12 plate holders, so its a case of finding the right plate holders to fit the camera.

    Typically good working Avus type 9x12's sell for around £15-£30 ($30-$60 US)

    A particularly nice variation aZeiss Tropica was the subject of a thread recently.

    Good luck finding a camera

    Dear Tim,

    The small amount of Slavich stuff I've seen has been variable, but that was some years ago. They may well be better now. I'd only make a modest investment at first, but at the right price, yes, I might buy a dozen 13x18cm plates. It they were good, yes, I'd probably buy more.

    Cheers,

    plates

    Great idea Tim,
    I would love to use some 1/4 plates (3.25x4.25) on my Graflex Series B. Count me in for a few dozen. I so wish that glass plates would make a comeback..........

    I asked the "why" of using plates, because I do have plate holders for some cameras and wondered the supposed "advantages". If there are compelling advantages, then I might consider being a part of this order.

    Just an observation....If Slavich makes plates for Holography, wouldn't they have to have good quality control?

    According to Kodak, glass plates coated with TMX emulsion are available. Anyone really serious about using glass plates and concerned about quality control should consider these. This taken from the Kodak Web site here: http://www.kodak.com/global/en/profe...f32/f32f.jhtml.

    "KODAK T-MAX 100 PROFESSIONAL PLATE

    The KODAK T-MAX 100 Professional Plate is a continuous-tone panchromatic plate that has the same sensitometric characteristics as KODAK T-MAX 100 Professional Film / TMX. It is especially useful for photomicrography, electron micrography, and laser recording, as well as solar and astronomical photography. It provides maximum image quality for detailed subjects. You can process this plate in KODAK T-MAX RS Developer and Replenisher, KODAK XTOL Developer, KODAK HC-110 Developer (Dilution B), or KODAK Developer D-76. For ordering information, see a dealer who sells KODAK PROFESSIONAL Products."

    Glass plates are I think still coated with Ilford emulsion, by hand but not by Ilford.

    A few years ago I was talking to an Ilford research chemist and one of their sales team over lunch, we were talking about people hand coating emulsions, I mentioned that a company called Barfen were selling a B&W emulsion in the UK to amateur photographers, they'd never heard of it. (I never tried it).

    I got a call a few days later and was told the Barfen emulsion was actually an Ilford Nuclear emulsion, they hadn't known about it as the nuclear emulsions were a separate division.

    Ron (PE) has posted a link on APUG showing one of his friends demonstrating the technique for hand-coating a plate.

    Here's a possibly silly question, except that I don't know the answer...

    I know solutions exist for those wishing to load and expose film in older plate holders and cameras. Inserts, sheaths, etc. But is there such a thing as a modern holder, in standardized dimensions for use in modern film-based large format cameras, that is designed to natively hold glass plates? In other words, the opposite of the direction most people seek to go.

    If I knew I could use my existing 4x5 Wista and/or my existing 8x10 Calumet C-1 with a holder designed to natively hold a glass plate, I would indeed be interested in trying them out. And maybe even try coating my own. But I don't want to have to acquire antique plate holders and a matching camera to do so. (My other half would... well, you know the rest.)

    I have some "modern" plate holders in both 5x7 and 8x10. Glass plates are still used in applications that require perfect flatness and good dimenisional stability (astrophotography, etc). So you can come across them -- I bought mine on ebay.

    More people are coating their own plates these days, so modern plate holders seem to be going for a higher price.

    Yes, there are.

    There are the Linhof Universal Film & Plate holders ("mit Auswerfer") in 9x12cm, 4x5" and 13x18cm, which fit 4x5" or 5x7" cameras. Unfortunately the Slavich plates are a little bit too thick to use in these, at least in 9x12/4x5".

    There are also Linhof adapters for using single plate holders in modern cameras; I have a 9x12cm (4x5") and a 10x15cm (to 5x7") version of these with appropriate plate holders. These plate holders will take the Slavich plates.

    A third version is original wooden book-style plate holders for modern backs; I have three of these for 18x24cm plates. They fit perfectly in any modern 8x10" camera.
