Some people have noticed a more purple hue to a lot of sunrises and sunsets recently. This seems to be due (“they” think) to dust and sulfur in the atmosphere from a volcanic eruption in Russia. I noticed it to be very prominent in the sunrises and sunsets when I was out in the desert last month.
Even in the last few days here in LA it’s still a visible effect.
Even when you stop down the lens to not blow out the exposure, it’s still there, although not as saturated.
Nice gradient you’ve got there!
What color is your sunset?
