I actually use thin black plastic from modelmaker's shops. I bought some years ago and its lasting well. With a new scalpel blade they are simple to cut out and adjust and the centre is drilled out. Some really early lenses used stops in 1/8" or 1/16" intervals, probably due to these being easily available drill sizes. No f/numbers then! 2 1 Link to post Share on other sites More sharing options...

willeica Posted November 23, 2023 Share #944 Posted November 23, 2023 For the past 9 months I have been cataloguing the collection of the former Photographic Society of Ireland, which was founded in 1854 as the Dublin Photographic Society. I have found many treasures there and I could post about a lot of interesting items and will do so over time. Last week I came across 3 Cp Stirn's Vest or Waistcoat cameras from the 1880s and one of them contained a developed circular negative plate, containing 6 images, which I have inverted and cropped to show that they were taken at an equestrian event in May 1888. The name Capt Scott is there , but I don't believe this is related to the famous Captain Robert Falcon Scott of Antarctic fame. In 1888 Cape Scott was a 20 year old Midshipman in the Royal Navy.

Technical details of this model are here. http://www.earlyphotography.co.uk/site/entry_C6.html https://www.19thcentury-photography.com/product-page/c-p-stirn-s-geheim-camera-alexandria-c1890 The camera was also called a 'button-hole camera' as the lens could be pointed out through the button hole of a vest while the body of the camera was hidden behind. It was not really intended for equestrian events, but rather for what people today call 'street photography'. Some examples of that are here. https://www.exibartstreet.com/news/19th-century-street-photography-with-a-spy-camera/ William 8 Link to post Share on other sites Simply register for free here – We are always happy to welcome new members!

I have a number of sets of magic lantern slides telling traditional stories (Cinderella, Aladdin etc), which are all hand painted. I have a Watson quarter plate, tin plate magic lantern, which belonged to either my grandfather or his brother (both of whose Leicas, a model II and a model III, I still have). Sadly the original acetylene lamp was converted, I suspect during the 1930's by my uncle, to a 175V projector lamp to suit the 175V DC generated electricity at the family textile works but using the original parabolic mirror and condenser. The 175v projector lamp is also now dead but I may be able to obtain a 240V replacement. Wilson Link to post Share on other sites More sharing options...

The Kromograms are black and white stereo pairs, but when viewed through the Red, Green and Blue filters built into the Kromskop they reveal themselves in colour. The photography is the reverse of this. Images are created using colour filters As you know, B+W plates can be sensitive to certain colours and when the process is reversed for viewing, the colours are revealed. It is an additive process as opposed to the subtractive process often found in colour film. I will try to do justice to them with my post next week. A lot of lantern plates were hand painted, some good, some not so good. There are examples of painted slides in the collection, but it also contains examples of early colour processes such as that of John Joly of Dublin and also commercially produced processes bought from GB e.g. the Paget process. One very rare thing we found in the box with the Kromskop was the original 1890s manual for the Ives process. Real skin on hens' teeth stuff. As regards magic lanterns, we have have found all kinds of illumination solutions for lanterns, such as 'steam punk' style paraffin lamps with 4 wicks. I think I will have to do a weekly post on this stuff. William Link to post Share on other sites More sharing options...

It might just be worth looking into an LED replacement which will run much cooler and will require far less power. Some are now quite extraordinarily bright.

Pyrogallol Posted November 24, 2023 Share #950 Posted November 24, 2023 I made an LED replacement lamphouse for my Lines and Jones halfplate enlarger, about 60 lights in a panel, only 12volts and no heat. Link to post Share on other sites More sharing options...

Some are now quite extraordinarily bright. Temporarily, I have been using my Olight X7R LED torch, at one of its lower settings. These settings unlike the higher power settings are not thermally time limited, are quite bright enough for projection. However the zig zag filament projector lamps have nearer the correct steam punk feel for the magic lantern. The base of the burnt out lamp appears to be a Kodak aluminium 35mm cassette tin. I do have an acetylene lamp but it is not very bright and was intended for caving or mining rather than projecting. It is also rather smelly in operation, with an odour of rotten garlic. I suppose given how smelly coal mines are (has to be experienced to be believed. I was taken down a coal mine in the Rhonda valley as a teenager by a GP who was a childhood friend of my father), the additional smell from the carbide lamps would never be noticed.

Wilson Wilson, if you want the real 'steam punk feel' here is the item for you. A Stocks Patent 4 wick paraffin burner from the collection which I am cataloguing. Welcome, dear visitor!

You could also go in another 'steam punk' direction and get something like this 4 lens Noakes Quad Magic Lantern from 1897. This was made by David William Noakes in his own workshop to illuminate his own lectures and was up for auction recently by SAS. I have not checked to see if this sold and, if so, what it fetched. Some period photos of the device are below. William 5 Link to post Share on other sites Simply register for free here – We are always happy to welcome new members!

I remember playing with carbide as a youngster by throwing it into water followed by a lump of sodium metal; this was in my mispent youth when I was well into chemistry. Its an interesting concoction and almost impossible to extinguish. Possibly not to good on the H&S ways of the current world. And fortunately you probably can't buy either easily I would hope! 1 Link to post Share on other sites More sharing options...

I bought my carbide to try out the lamp on eBay. A 5kg bag was about £10. I remember setting off large amounts of flash powder, where we found a large unopened tin of it in the school theatrical supplies cupboard. I think you can still buy flash paper and flash cotton in the UK and probably even easier in France. Wilson 1 1 Link to post Share on other sites More sharing options...
