To be really meaningful, you would need to scan both the old and the new at the same time and to the same specification…

Since MF scanning at high resolution is very time consuming, you’d want to reserve it for the very best images, so The Stereoscopic Society decided to scan its MF images at 600 DPI which yields scans big enough for practical purposes (printing, projection etc), but you really need 4000 DPI if you want to analyse the basic film qualities…

 Just for interest, I’ve attached a scan of  slide taken by John Singleton at Bekonscot Model Village in the early 1930s – soon after it opened.  (If the attachment fails, I’ll put it in the images area of the group…)

Tee hee, I wondered if you would comment on that!

John Singleton, who took the image, was an executive for a major oil company, and he seems to have been an “early adopter” in many ways.

I think this is some very early Dufaycolor and, even scanned at 600 DPI, you can see the colour patterning. It was used for one motion picture and I think 120 stock was introduced in 1933 (35mm in 1935).

Of course, its days were numbered with Kodachrome coming along soon after.

In the Stereoscopic Archive there are actually 14 stereo pairs of Bekonscot taken very soon after it opened. I’m hoping to make some ViewMaster reels of them to take to the Model Village to show to the people there – I suspect they will be VERY surprised to see their park in it’s infancy, in colour AND in 3D!

Are there many 1930's MF 3d slides or prints out there in color?
