Description: a corona around the Moon was seen also today in the sky of Seitseminen National Park. The corona was caused by fog at surface level. This time only the aureola (the innermost ring) was visible. It means, that the droplet size distribution of the fog was rather large. Based on the apparent size of the aureola, the mean size of the droplets was pretty small.
This time I tried to make a HDR image of the corona. I took series of photos of the Moon and corona with exposure times from 0,5 s to 10 s. By doing like this, I was able to take some shots with the features of the Moon visible and shots with the landscape and trees visible. Then I stacked and edited the photos with GIMP software to make the HDR effect in the image.
And actually the HDR images are a new form of art to me! This was actually my first HDR image ever that I have made! There’s still lots of things to learn about this artform, but you got to start somewhere! I’ll keep on practicing with doing these HDR photos and some day I’ll write a different post about making HDR photos of celestial objects and phenomena!
