The cold sun in the sky and afternoon shadows herald a chilly night. Snow coming soon.
I don’t get the sun’s rays or star by using a special filter. I use just a skylight filter to protect my lens and not on every lens, either. I can get the star effect by angling the camera when the sun is in front of me. I have to twiddle with the position of the camera until I see the star and then shoot. It’s not a special effect, just optics.
