1906 article re Wollensak’s solution to media insensitivity to blue light
Toronto. … or so said Chicken Little in the Children’s fable (I learnt the English version … ). For many years film and glass plates were basically insensitive to blue light (orthochromatic) so clouds and sky exposed for the landscape came out as white (ie. severely underexposed). Some filters solved the problem with a half clear bottom and a yellow top.
Wollensak, in this article from the Amateur Photographer for January, 1906, came up with a novel shutter solution. Its ‘Skyshade’ shutter slowly exposed the sky at a varying speed while the landscape was exposed at an adjustable ‘fast’ speed. This was all done with the shutter mounted in front of the lens and the camera securely mounted on a tripod.
Our thanks to my good friend, George Dunbar, for sharing this historic article with us.

Toronto. Did you know that microfilm images have been around since the beginning of photography? The role of John Dancer is recorded on the Collectors Weekly website under an article called, “Royalty, Espionage, and Erotica: Secrets of the World’s Tiniest Photographs (the image to illustrate this post is courtesy of their website).
The source of the name ‘Stanhope’ is for the type of lens used to view these tiny marvels instead of a much more expensive microscope.
The role of the Stanhope lens is also noted there and in a Wikipedia article. A few of our members collected “Stanhopes” which came in many guises. All used a Stanhope lens and a tiny positive image viewed by holding the lens between the eye and a bright light source.
NB. The title is a riff on the book “Mr Standfast” by one of my favourite authors – John Buchan – also known as Lord Tweedsmuir (and governor-general of Canada back in the day). At least one of his books – “The Thirty-Nine Steps” written in 1915 – was adapted for a movie of the same name.
adding needed light for action shots
Toronto. In today’s world of smart phone ‘auto everything’ cameras, it is hard to imagine sensors so slow that sharp outdoor action shots are a no-no. But in the late 1940s, colour film was just that. Its sensitivity was abysmally slow.
Portraits and landscapes were great outdoors in full sunlight. But, for action shots, even in full sunlight, colour film sensitivity was just too low. Even a decade later, I found Kodachrome, at a crummy ASA 10, left the outdoor shadows in darkness if the highlights were correctly exposed (using a 35mm camera lens at f/2 and a shutter speed of 1/25 second or so).
So what could be done to take an action shot (especially using a press camera)? One could follow the subject and let the rest of the scene go blurry. One could use a strong flash. But what if the flash was too weak? Well, a more powerful bulb might have worked. No room for a larger bulb? Then multi flash guns could be used like shown here.
The article shows how one New York photographer (Oscar ‘Ozzie’ Sweet) solved things by concocting a support holding an array of flash guns, all set to fire when the shutter was released. As shown, the array was used with a press camera. Lenses for such cameras were a bit slow, even when used ‘wide open’.
The article is in Popular Mechanics (the March 1948 edition) and is presented here thanks to my good friend and fellow PHSC member, George Dunbar. George found it while seeking historical material in magazine ads and articles.
Kodak Canada Website
Toronto. In the days of print, camera makers, photographic chemistry manufacturers, studios, etc. used printed media to promote their wares. In fact George Dunbar has used the various magazine ads and articles of yesteryear as a source of photographic history. City directories, newspapers, in store displays, house organs, pamphlets, etc. were other sources of information.
In today’s world, the photographic mavens resort to the internet using web sites (such as Kodak Canada), social media, Youtube channels, etc. instead to promote product. The printed word, be it magazines or newspapers, is in decline while social media and the like are flourishing! Which raises the question – how will future researchers learn our rich photographic history?
Note: The post title is also a song title. In this case it is a song sung in, “The The King and I“, by Julie Andrews. While sourcing this song, there was some confusion over “The King and I” and “The Sound of Music” as the source. In any case in my selection, the actor is Deborah Kerr but the actual voice is that of Julie Andrews!
A fall 1947 article on side flash activated by on-camera flash
Toronto. In this day of smart phones, it’s hard to imagine an accessory that was about 10 pounds in weight and a six inch square ten inches high with a flashgun stuck on the top and a tripod thread stuck on the bottom. …
Worse, the accessory (right photo) was to add a modelling light (centre photo) to a face illuminated by an on-camera flash (left photo).
We take smart phones for granted with their tiny, ultra light cameras and a tiny computer set for ‘auto everything’ so every photo is technically correct (subject, steadiness, and framing may vary). The contrast of a 1947 ‘accessory’ and a 2022 smart phone reminds me of that old adage, “we get too soon old and too late smart”.
George Dunbar, our good friend and fellow photo enthusiast generously sent along this bit of history in the form of a brief article on an extra flash triggered by the on-camera flash. The article once appeared in a September, 1947 issue of Popular Mechanics. Before smart phones took over, we used off camera bounce flash to model the subject and soften the shadows – sort of a one flash lights all.

book by Ken Burns
Toronto. I first learnt about Ken Burns via iMovie. The Apple App had a spot for effects and even came with one – the Ken Burns Effect. Burns as a documentary photographer used his effect to zoom and scan stills in his videos to give a sense of motion.
I was surprised to hear that Ken is also an accomplished photo editor of historical photos as demonstrated by his book, “Our America“.
George Dunbar brought this to my attention. George writes, “I’ve been spending some enjoyable time with a magnificent new book, ‘Our America’ by Ken Burns. This huge, coffee-table-size volume, displays the excellent photo-editing talents of this famous documentary film-maker. He’s chosen about 250 images that beautifully capture the essence of America from 1839 to 2019.
“Most of the amazing images are entirely new to me since Mr. Burns and staff have obviously scoured the contents of many useful archives. Although all images depict American life, this book is a treasure-house of historical photography that will surely interest viewers worldwide.
“P.S. It’s available at the Toronto Public Library.”
