Setting sun at Loha Prasat Temple, Bangkok, Thailand
It’s been a good winter for red suns so far. I’ve photographed this phenomena three times in the last month, twice in Bangkok and once in Koh Kood.

Due to the oblique angle of the sun when low on the horizon, light must travel through more atmosphere to reach us (see diagram below). Blue light, with a higher frequency wavelength than red or orange, is scattered and absorbed by dust particles in the earth’s atmosphere away from our sight, leaving only the lower frequency red and orange wavelengths to get through.
Camera exposure affects the colour of the evening sun too. The picture above exposes for a little detail in the temple roof compromising the exact red colour of the sun, over-exposing here almost to white. With the naked eye I see a redder sun but happy to let the image stand as is.
