Oxford: Ilford F.P.4 Glass Plates – part 1

Sunday, September 15th, 2024

Here are some portraits I recently made on Ilford F.P.4. dry glass plates which expired circa 1950. The box doesn’t have a visible expiry date that I can find but the label design (see below) was dated by Nicholas Middleton who has done some research about it. His excellent photo blog contains a wealth of information about various old film stocks, cameras and glass plates he has tested. Following his advice I rated these glass plates at ISO 5 which gave me an exposure time of approximately 2 seconds in shade. The Ross reflex camera I used has been serviced and inside is a date of manufacture from 1915 written in pencil. The camera is in excellent condition considering it’s over 109 years old. I still have two more plates to develop and six left to use.

[Tech info:] Ross reflex, Zeiss 11.5 inch f6.3 lens, Ilford F.P.4. glass plates @ ISO 5, developed in Rodinal 1+100 for 1 hour semi-stand (slow agitations at 30 mins).

Oxford: glass dry plate portrait

Friday, March 1st, 2024

Here is my first portrait on dry glass plate. I found a box of old Ilford FP4 glass dry plates at home and have no idea when I bought them. The box doesn’t have an expiry date on it. As luck would have it they’re the correct size  (2.5 x 3.5 inches) to fit the Mamiya Press plate holders I’ve got but so far have been unable to make use of. This portrait of another fellow photographer during his visit to Oxford was made last weekend in Radcliffe Square. I don’t know him but I enjoyed chatting about photography with him as I set up the shot. I’m very pleased with this result (it has a vintage feel to it) and look forward to making more portraits with the remaining glass plates. The emulsion is very fragile when wet and you can see it lifted along the right hand side.

[Tech info:] Mamiya Press Super 23, 100/2.8 lens (at f4), FP4 glass dry plate exposed at ISO 10, developed in Rodinal 1+25. (Thanks to Nicholas Middleton for his inspiration and blog posts full of info about using old glass plates).

Vintage: glass plate photography

Thursday, April 12th, 2012

This is the first blog post I’ve made that doesn’t feature any of my own photography and to be honest I don’t know who the original photographer is. All I can tell you is that a box full of these glass plate negatives was on sale at a local charity shop here in Oxford and last week they were purchased by a gentleman visiting from the U.S. – he has been very generous to allow me to borrow them so that I can make some contact prints. I only borrowed them earlier today so I was keen to make some scans to see exactly what was on them.

All of the images in the box are of window displays for a tobacconist called Lewis. The name Lewis is handwritten in pencil on the outside of the box lid and some of the plates have reference numbers written along the edge as well as location information. One of them has Luton written on it. The measure approximately 6.5 inches x 8.5 inches and I can only assume that the original photographer was photographing these shops as a commercial job, commissioned by Lewis to do so or it was a personal project. It makes me a little sad to think of all of the work that went into making these images however many decades ago and they end up being donated to a charity shop.

Many thanks to Ken for the loan of these glass plates. I really enjoyed scanning these and I look forward to making some contact prints from them in the coming weeks.
