This post compares an InGaAs camera – used for Infrared Reflectography (IRR) with a Digital camera modified for Infrared photography (IR). An InGaAs camera is your choice when it comes to imaging underdrawings. Though, the advantages of the InGaAs camera, even if real, are limited. So, we should be aware of them before we decide
I noticed I often talked about Infrared Fluorescence Photography in my posts, such as the one on historical pigments, and the one on the Windsor & Newton Gouache color chart, but I didn’t properly introduce the technique yet. This post wants to be a brief review of the Infrared Fluorescence Photography. Infrared Fluorescence Some molecules and minerals
I took this image from my Lab, a couple of weeks ago. I live close to Mount Etna, the tallest active volcano in Europe, about 3,300 m high. Etna is in an almost constant state of activity and we are kind of used to those smoke plumes. April 2013. Etna eruption seen from my Lab.
This post introduces MultiSpec,the Multispectral Image Data Analysis software that I use. It’s free and pretty easy to use. On their website you’ll find tutorials and examples to learn and master it, so, I’ll just give here a very simple example of its application for examination of art. Just to let you see how neat
You can enjoy this post about two little science experiments with the IR digital camera and the InGaAs camera we use for art examination. These experiments have nothing to do with art documentation but, I know, some of you are scientists and would enjoy them. Blackbody Radiation and Thermal Infrared A thermal camera is actually
