Iceland 22° Halo
This is a picture of a slightly surreal scene we came across on our recent trip to Iceland.
[See more on my Facebook page]
At the time I shot this, we were already hours behind schedule driving across the country but I couldn't resist stopping to get one more quick "road shot" as this sun-halo appeared across the sky.
I thought it was a rainbow at first, but quickly remembered that rainbows only appear when you have the sun at your back. So at the time I didn't really know why I was seeing what I was seeing.
But after a few minutes googling I learned that this phenomenon (a sun halo, or 22 degree halo) is caused by the refraction of light through ice particles which are suspended in cirrus clouds.
Only visible at a very specific angle apparently!
Anyway, there are a few technical issues with this shot. Not least the wide angle distortion which is stretching the edge of the halo so that it's not completely circular. I might fix that later, but I didn't want to spend too much time on it because of the other small problems (mainly caused by me rushing the shot).
