Ok, this is an image from today with my new yellow filter to get more contrast on my b&w cloud pics. The clouds late this afternoon were big fluffy santa-beardy fluffballs.
This one had a neat sort of keyhole in it, and I was thrilled to see the filter helped me capture the crepuscular rays. Neat stuff!
Click here for one of the best sites I've seen on optical effects in clouds, sun/moon, etc. Great site. I can spend hours there looking at stuff. Beautiful.
