Simon Marsden tribute movie on the way

At first I didn't quite 'get' the aesthetic of the late Sir Simon Marsden's infrared photographs. Based on my own experience of using the legendary Kodak HIE infrared 35mm film, I found them rather gloomy. Eventually I clicked and began to appreciate the atmospheric effects he was achieving. His use of strong back-lighting, dramatic angles and his expert printing soon made me realise that he, and the grainy halation of HIE, were made for each other.

Ironically, as many of you know, that grainy halation was a result of the construction of the film rather than the infrared light itself. However, the film was constructed like that because of the infrared light: the lack of an anti-reflection coating and base fogging being because Kodak couldn't find a way to make them work across all the wavelengths to which the film was sensitive.

When I came to work on the Infrared 2010 celebrations, I was delighted with how helpful and communicative Simon was. This was true of almost all the photographers I approached but Simon was the only one who was actually specialising in infrared photography. His Moydrum Castle photo from 1978 became our poster image.

He died suddenly in 2012. He died on my birthday. I was 61, he was only 63. We had communicated, chatted even, using email. I had never spoken with him or met him. An opportunity missed.

The Irish film maker Jason Figgis has been planning a film about Simon for at least a year—entitled Simon Marsden: A Life in Pictures—with the enthusiastic support of Simon's widow Cassie. Jason's blog about the project had its first posts back last July and has been quiet so far this year but I know the project is now ramping up. It will explore not just Simon's work but also the technical background and inspirations behind it.

Stay tuned, as they say.

Ed Thompson Kickstarts Book

Ed Thompson is running a Kickstarter campaign (is that what you call them?) for his book 'The Unseen'. If you're interested in Ed's thoughtful takes on false-colour infrared photography then you should have a look.

It's highly unlikely anyone will produce any more colour infrared film, so there's something rather wistful about looking through this book, knowing that the images represent the last ones to be captured using this idiosyncratic stock. It started life during the second world war as a means of detecting camouflage and was used extensively for remote sensing and medical photography. The Unseen takes a sideways look at the historic uses for the film with subjects like Chernobyl, bees and even a haunted village (Simon Marsden would have been proud).

The book is expected in June. My full disclosure is that I've helped Ed in a small way with some of the text.

Laurie Klein Artistic Techniques Book

Following on rapidly from her excellent book Photographing the Female Form with Digital Infrared, Laurie Klein has joined forces with her son Kyle for a more general coverage of infrared photography.

Basically (and simplifying somewhat) Kyle discusses the subject from a technical perspective while Laurie discusses the art and technique. As I noted in the review for Female Form, Laurie studied with Ansel Adams and his fingerprints can occasionally be found in her work. This book even mentions the Zone system, in the context of using the camera's histogram display. For infrared photography, where the captured images often have a restricted palette, the histogram is even more useful than in conventional photography.

There's a lot to glean from this book. Personally I find more to learn in Laurie's contributions but that's not to denigrate what Kyle wrote, just where I'm coming from with my research into the subject. What I really like is that post-processing, which is undoubtedly an essential part of digital IR, is placed in a reasonable perspective. The book leads you through the workflow of making the image with the camera and then adjusting it to match the vision. I'm particularly interested in the section on emulating the old Kodak film halation and will be exploring that before long.

Infrared Photography: Artistic Techniques for Brilliant Images by Laurie Klein and Kyle Klein is published at $37.95 by Amherst Media. I note that Amherst have really upped their game with the printing in their recent books: no complaints on that score. The format fits the usual Amherst US-Letter size, perfect bound.

I've also been sent a copy of Karen Dórame's Mastering Infrared Photography by Amherst, which I'll be looking at before long.

Infrared rainbows

It was Robert Greenler who, having deduced that there should be an infrared component to a terrestrial rainbow, finally succeeded in photographing a natural one in 1970. I've had a go myself and if the sky does what you need and the camera is steady enough it is not too difficult to give it a go yourself.

Scientific American recently published an article entitles Think You Know Rainbows? Look Again, which discussed and showed examples of rainbows that were not particularly rainbow coloured, including a white one and a red one.

The red example in the article (reproduced above) was taken from the Wikimedia Commons, and was taken by Jason Campbell in 2011. The cause, as the article explains, is that the light source is a setting sun and at this point only red light was available to be refracted by water droplets to form the bow.

You probably see where I'm going here. Let's assume that near-IR is also in the sunlight as the sun sets and that this remains a little after the red has gone. In this case it should be possible for an infrared-only rainbow to exist.

Presumably anyone with a suitable light source and some fine mist could produce one in the lab but has anyone managed to take a photograph of such a thing 'in the wild'?

[As an aside, I recently saw that the light from a rainbow is polarised along the circumference of the bow. Obvious when you think about it but I'd never noticed before.]

A new inexpensive thermal camera from CAT ... in a phone

Last June I had a chance to look at the Flir One thermal add-on for the iPhone. This was based on Flir's tiny Lepton bolometer. This has a resolution of 80 by 60 pixels and is aimed at OEMs to incorporate in various devices.

The latest is an Android mobile phone from Reading UK-based CAT called the S60, which was launched yesterday at the Mobile World Congress.

The CAT literature doesn't mention thermal resolution, although there is some online speculation that Flir's Lepton is now available with 160 by 120 pixel resolution, as reported by Ars Technica last August. Whatever it is, the CAT device seems to make use of the same blending technology that the Flir one uses to give false-resolution to the thermal image, which makes it much more useful. The visible and thermal cameras are also much closer together in the CAT, which will reduce need to correct the parallax errors at close distances that the original Flir One exhibited.

This is still not really of a sufficient 'quality' to be an artistic imaging device, but if you're a plumber, heating engineer or electrician this is a kind of tool that will soon be making its way into your toolbox.

You can see the BBC's Rory Cellan-Jones trying one out, and chatting to 'the man from CAT' in this video clip.
