Mid-Monthly Musings January 2012Mid-Month Musing January2012
I thought we should introduce a new monthly feature where we take a topic of interest to the Group, present some examples from submissions, and invite discussion. To start off, I am going to look at three recent examples from our Experimental folder that illustrate the idea of extra-visible imaging in non-infrared work.
The image, “City Walks”, by Intergativeone http://intergrativeone.deviantart.com/ provides my first example. A street photograph of three young women in colourful attire shot from behind with a shutter speed of ½ second, the image shows substantial time blurring, yet
Best of January 2012 - Winners AnnouncedBest of January 2012 from the Infrared-Club (Extra-Visible Imaging).
With 100 submissions to the Showcase Gallery and over 20 to the Experimental Gallery this month, the admin staff, (Associates and Expert Members), have had a tough task deciding on the Best of January. The following fifteen images from ten photographers have all received two or more votes, and represent outstanding work from ten of our members. They fall into two main groups – people shots and landscapes – with the people shots having strong contributions from Indonesian photographers and the landscapes from European and American contributors.
Ten images, one

Best Entries for November-December 2011 as chosen by the admin staff.
The following have been placed in the Featured Gallery and are discussed briefly here. Following the reorganisation of the Group, we have been very heartened by the support shown by members by way of submissions and comments. We have also had several new members, some of whose work is seen below.
I am not going to pick a winner, but the first two entries were picked by each of the five admin who took part.

| Send a question via the Group's Comments Box and our experts will attempt to provide an answer. For Example: Auchencairn asks why sometimes skies are black in IR photos, but at other times they are not. Nick (spigget) replies: Generally speaking the sky is mostly transparent to NIR (750nm-1400nm). Less rayleigh scattering, darker sky. For example, place a couple drops of whole milk into a glass of clear water and you will get a good model of the earths atmosphere. If you look at it up to a light source you will notice that the light source is a yellowish red color. This is because the shorter wavelengths of light are smaller and more easily scattered by the fat particles. The same occurs in the atmosphere. UV gets scattered the most and IR the least. The reason you are getting mixed results is probably more to do with the subject matter itself than the sky or the filter, although smoke/haze, and angle relative to the sun do affect the sky brightness in IR, and so do filters. For example, if you choose a subject such as a lush green rainforest or palm trees and take a photo of that with the sun to your back you will have very dark sky and very bright trees. Direct sun in combination with the scattering of light going away from you makes for very bright/dark contrast. If you shoot into the sun, you will see more scattering in the atmosphere and the side of the trees in the shadows. This is generally not as evident in the visible range because the sky contributes a lot to the fill in the shadow area. Something that is a good experiment is taking your IR filter and placing it over your cellphone camera lens up close and seeing what things look like in IR realtime. >720nm fliter ish generally works the best in combination with a cheap phone or digicam. That generally gives me a rough idea of what the final image will look like. Hope that helps, and let me know if you need any clarification. Jonny (JonnySutton) replies: That would depend on the type of filter you are using, as non-IR light will slip through some filters and the sensor is MUCH more sensitive to these which means the sky will not be black, it also depends on your exposure setting, have you under or over exposed perhaps? Other than that it would be due to the amount of IR reflected by the sky, I am not 100% certian but I would expect the amount of water vapor in the sky (temp and humidity would play a factor) this would alter the skys reflective characteristics, also, we see the sky as blue in the day, but as red at sunset due to the height of the sun and the way it scatters light in the atmosphere, I expect that would have an effect. Feel free to add anything if you know more about this Jonny |
