Here, we present some basic case studies on the application of our colour transformations. The most straightforward one is the image processing of the natural sky with no light pollution. This provides the basis for further studies where some of the emission sources (natural or artificial) exceed the others. It gives a possible reference point. The next example is a location with low light pollution (dark sky park in Hungary); it demonstrates the effect of light pollution on colours. The third demonstration is the processing of aurora images. Here, the correct colour processing is essential, since the source of the emission is then predictable from the colours. In contrary, the erroneous processing of the images may predict incorrect physical process behind the emission. In a forthcoming paper, we analyse additional night sky scenarios, for example, observations with intensive airglow in the oxygen or sodium lines. We are performing a long term light pollution survey in Hungarian national parks and some other locations—when a sufficient amount of data will be collected, we will analyse these data with the same methodology.

Here’s an exercise you can try for this:

Start by listening to an audiobook at a comfortable speed. Listen to the audiobook at that same speed for 10 minutes. Move to the next level of playback speed. Listen to that next level for 10 minutes. Change the speed levels every 10 minutes. The goal is to get to a rate where you start feeling a bit overwhelmed or stressed. You’ll know you’re there when you begin to focus too much on the words rather than comprehend what you’re hearing. Return to the previous level of speed once you become uncomfortable. Consider that speed level as your current maximum speed capacity. Listen at this speed as long and as often as you can. The idea is to be able to listen to the content without the reader sounding like a chipmunk. Repeat Steps 1-7 every two days. Your maximum speed should be gradually improving.
