Talented or What?Talented or What?
A couple of weeks ago, I read a snarky article by a Times journalist bemoaning the fact that billions of images were being made and posted everyday by people using social networking sites such as Facebook and Twitter. “What had the world come to, when that was all they could do with their time, and what rubbish was being produced”, was the general tone of the article. I take exception to that view, strong exception. The Digital Age with the advent and rise of mass photography and other forms of digital art, whether on Facebook or other sites is one of the greatest advances in creativity to have taken place. Just about everyone now has the means to express themselves in ways inconceivable in my youth. On DeviantArt, looking at the wealth of art being made across such a wide spectrum techniques, I might well reverse the argument and say, “What has the world come to when such wonderful creativity can be seen, expressed and appreciated by t
Hot Spot Thots
A hot spot is a noticeable color aberration, usually circular, that appears in varying amounts in digital infrared photographs. Some lens and camera combinations seem to be hot spot free, but most lenses show some degree of this problem.
Photographic lenses are not designed with IR in mind. IR focuses differently than visible light. It reflects and diffracts differently than visible light. The lens elements and the inside of the barrel of any given lens may be prone to uncontrolled reflection and diffusion of IR. There may even be reflection from surfaces inside the camera body. Also, different cut-off frequencies of IR filters can reveal differing degrees of hot spotting.
In its most obvious form, the hot spot is an area in the center of the photo that is a contrasting color to the rest of the image, fairly saturated and rendering the elements in that area flat and softer focus. In many cases the hot spot is less obvious and can be managed during post processing.
The most subtle hot s

Canon 40D Conversion - Full Spectrum ImagingCanon 40D Conversion – Full Spectrum Imaging
I thought I might describe my work with my recently converted Canon 40D camera, partly for my own records and partly in case others might want to see the pros and cons of working in this extended medium. Many of the images to which I refer and that are reproduced here are to be found in the galleries of the Infrared-Club (Extra-Visible Imaging) :iconinfrared-club:, particularly the Reference and Tutorial gallery.
My Canon 40D was converted by Advanced Camera Services (ACS) http://www.advancedcameraservices.co.uk/html/ir.html a company in Norfolk,UK, for about £325 (including VAT). The conversion involved removing the infra-red reflecting hot mirror, and replacing it with a quartz filter that allows ultra-violet light, visible light, and infra-red light to reach the sensor array, the full spectrum range being about 380 nm at the UV end to about 10
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 conveys considerable visual appeal in its composition, colour, abstraction and movement.
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 from each photographer, are in the Best of the Month Poll . The are arranged in a random order. Please vote for your favourite and we shall run a feature on the winner in a couple of weeks.
Here are the people shots:
Best of November-December 2011Infrared-Club Extra-Visible Imaging
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.
“Angel” by 3whiteroses http://3whiteroses.deviantart.com/
“Red Red Hot” by dewanggapratama http://dewanggapratama.deviantart.com/
The Angel is a haunting IR portrait shot, while Angga's model illustrates the power of the more full spectrum approach.
The surreal nature of infra-red is always near the surface, particularly in these examples.
