Dry Comparisons

I have now copied the glass plate from yesterday and also developed and copied the 5×4 film that I exposed at the same time to act as both a comparison but also a check that my process at the “taking” stage was correct. With the exception of shutter speed everything was the same – same camera, lens, aperture, composition. Everything locked down on a tripod so all I had to do was put the two holders into the back, set the shutter speed and press the cable release. The film was Fomapan 400 simply because that was what I had loaded and the glass plate was a J Lane 2 ASA plate.

Same scene, same camera and lens.

On the left Fomapan 400 5×4 film with a modern emulsion whilst on the right a 5×4 glass plate with a gelatin based emulsion created to an 1881 formula. The “vintage” emulsion is UV/blue sensitive whereas the Fomapan is panchromatic – you can see differences in the lupin flowers which are blue/purple and particularly in the enamel sign reflected in the mirror with its red tomatoes. Note also the bright orange flowers visible in the lower left portion of the mirror – the older emulsion renders these very dark whereas they shine in the panchromatic film.

More on what I’ve learnt so far in a future post but meanwhile here’s the dry plate in its solo glory.

    1. I look forward to seeing what you do with them 🙂 I’m going down pinhole route for next few plates
