This is another in the occasional series I’m running which highlight a particular vintage film emulsion to try to show how it looked when it was available many years ago. In this case the film I’m featuring is Perutz slide film.
For anyone who hasn’t heard of Perutz, I found this youtube video showing a 1965 TV commercial for it.
Perutz Slide film
I have to admit that I am one of that group who had never heard of Perutz slide film and when I first found some slides marked with the name, I assumed that it referred to the manufacturer of the slide mount.
After a bit of research however, I found a page which gave me some information about the film.
It seems that Perutz film was available from about 1960 to the early 1970’s and was both a film emulsion and a processing chemistry. This meant it needed to be returned to the manufacturer for processing; a set up which reminded me of Kodachrome, which was always supplied with an envelope to return the film to the lab and was purchased as process paid. At the time I thought it was for the customer’s convenience, but it was probably also to preserve the secret of the processing chemistry with the manufacturer.
This post features ten images from slides in my collection. There is one from the tower of London showing the entrance, eight showing a family on a sailing boat somewhere at sea and a tenth rather poorly taken image of a lake and some trees. The first nine come from a single collection of slides I bought many months ago, and the other slide came from a set I bought recently.
In order to try to preserve the look of the emulsion I have scanned these images without applying any sort of correction in Post Processing other than to crop out the over scan around the edge of the image. During the scan the only setting I adjusted was to set the exposure so that the slide was the correct brightness. Everything else has been left exactly as scanned to try to get as close as possible to the look of the slide.
The slides themselves are all plastic mount, as shown in the video above, and probably date from around the time that advert was made in the mid 1960s.
So, how does Perutz look?
Well, of course that is a completely subjective question and anyway this is only a small selection of 10 images, but to my eye the images on the sailing boat above have a nice colour rendition, and look bright and sharp. The image of the Tower of London does not look as good, but it was obviously a different day when the picture was taken so it’s not really a good comparison. The Lake and trees image is rather dirty and defocussed but also looks quite washed out and poor coloured compared to the sailing boat images.
I think Perutz certainly looks closer to Kodachrome than the other film I’ve featured in this series which was Illford and I tend to think of Kodachrome as the ‘gold standard’ of colour slide film. I’d be interested in anyone else’s opinion.
