IR and Clouds

How time flies. It is seven years since I purchased a Canon 1200D which had been modified for full spectrum photography. That means the IR cut filter which is normally installed on the sensor was removed and replace with clear optical glass. The camera now responds to light from near UV through the rainbow colours and into some of the IR spectrum. Previously I had used the camera as supplied, without any added filters. For IR photography it helps a great deal to add an IR pass filter to the lens. To that end I now have a R72 filter which passes light from about 720nm. The results? Great for producing B/W (grey scale) photos.

The photos are taken in RAW format and processed using Affinity Photo. First a photo which has had the colour saturation upped to maximum and clarity boosted:



The rest have had the colour saturation reduced to -100 and clarity boosted:











All taken along my lane today. Lots of Sunshine (needed with an R72 filter) and some decent cloud formations. The main problem when trying to frame the photos is the R72 doesn't let light through that the viewfinder can see so I cannot use the camera viewfinder. More a point and hope exercise. Once taken the photo can be seen on the LCD screen so a quick check can be made on the final result.
