This is a bit of a technical post so if you are not interested, just look at the pictures!<\/p>\n\n\n\n

A couple of years ago I tried converting an old compact camera (an IXUS 105) for infra red photography as a cheap way of trying it out. This wasn’t successful as the camera wouldn’t focus properly. I bought a second one cheap off ebay but never got round to modifying it.<\/p>\n\n\n\n

At the camera club in December there was a zoom meeting with a photographer who does a lot of infra-red (IR) and ultra-violet (UV) photography. I enjoyed the presentation so much I even bought one of his books. After reading the salient chapters I decided to have another go with the second camera.<\/p>\n\n\n\n

This was more successful as the filter you have to remove from the sensor wasn’t stuck in place (the first one I had to break to remove it). Using parts from both cameras I managed to get a working IR sensitive camera. This enabled me to make a first step in this world of strange colours…<\/p>\n\n\n\n

Note that this camera doesn’t have RAW file capabilities so I used the CHDK software to extend its capabilities and write DNG type raw files. Although this works the processor in the camera is slow so it takes a couple of seconds to process each photo.<\/p>\n\n\n\n

My first set of photos (after the initial tests to check it was working ok) was of the scene at the back of my garden just to see what happens. Here I show 3 versions of the image:<\/p>\n\n\n\n

The type of image after the IR conversion – colours are skewed – this was expected.<\/figcaption><\/figure>\n\n\n\n

This versions had the colour channels swapped in photoshop<\/figcaption><\/figure>\n\n\n\n
\"\"
This black and white version shows the classic IR style – dark skies and white foliage (green comes out as white).<\/figcaption><\/figure>\n\n\n\n

In this second set of images I tried putting a red filter over the lens – a classic trick for B&W photography in the days of film to get a dark sky:<\/p>\n\n\n\n

\"\"
In this version you can see the sky has a very strong red cast<\/figcaption><\/figure>\n\n\n\n

Here the colour channels were swapped around making the sky blue in this instance<\/figcaption><\/figure>\n\n\n\n

A monochrome version with darker sky and the white foliage<\/figcaption><\/figure>\n\n\n\n

This has given me plenty to think about and a chance to experiment before I go to the expense of having one of my mirrorless camera bodies converted…<\/p>\n","protected":false},"excerpt":{"rendered":"
