"Event looks interesting and some parallels with the history of photography. Penny post and maths in biology.
I am no mathematician but have signed up. Eclipse photography is of great interest to me too!"
"Spot on. Checking coating quality."
"This looks like a paper guillotine. Converting a slitting of paper into sheets. Not boring if you want to stay attached to your fingers!"
"This looks like a very basic film drier. A festoon of film was hung up with tension top and bottom in a climate controlled room. "
"This one is a more basic system. I am going to guess that it is the input end. Basic in that there is no base cleaning or input festoon. That must have been one boring job."
"Hi Nicola. I may be able to help with these. But not first hand - I didn't arrive at Mobberley until 1983!
This looks like the input (unreeling) or output (re-reeling) end of a film coating machine. I am going to guess that it is the output…"

"There are some high level Board of Trade export stats that might help, nothing that I know of that gives any detail. Kodak's records in the Kodak Historical Collection at the British Library may show something about its own exports"
British exports to Japan in the 1910s
I am interested in the types of photographic plate products made available from British manufacturers in Japan at around 1914. I am particularly interested in Ordinary, Photo-mechanical and Process plate availability.The reason for my interest is that Japanese academics of the time seem to have been taking different paths to their British colleagues. This may be down to simple availability of materials.See More
"Hi Tony. Thanks for that. They were indeed a 1930s product, introduced when Ilford had a Process Department. You can see where this product fits in the 1935 hierarchy here.
I have a little detail on that product but I may get back to you on…"
"Hi John,
I have several boxes of Ilford N50 halftone glass plates from quarter plate to 12x16 inch.
I think they are classed as high contrast thin film half tone.
I can open one of the boxes and see if there is any paper info inside if that's…"
"Hi Gareth. Fascinating story. I was 22 years with Ilford and we had similar machinations!
I am in the process of writing a history of Nuclear Emulsions, which starts with Process and Halftone plates around 1900. If you have knowledge of or contacts…"
Process and Half-tone plates 1895 onwards
As a part of a wider photo history project I am interested in the characteristics of these type of glass plates, sometimes also produced as flexible films. They were introduced from 1895 but were in production in various forms for decades.I have some comparisons from the 1890s Journal of the Royal Photographic Society and a little from the BJP. If anyone has manufacturers information in particular I would be keen to hear.See More
