I took my camera with me to the gym this morning because the valley tule fog was hanging thickly on my route and I wanted to try taking some photos in the fog. Quite a challenge I discovered, especially because the ISO was set to 1600. Once I changed the ISO to 200 I got better results but I should have changed the metering to spot metering from matrix metering so that I would have had better exposure on the foreground branches. I had to tweak the photo a bit in Aperture, using Auto RGB in the Curves setting to enhance the foreground branches. 
18-200 mm Lens at 62 mm
ISO 200
f/4.8
1/500
Beautiful, ethereal, spooky- and I love the composition!
You almost expect to see the Headless Horseman (or the Baskerville Hounds) come into view!! Thanks for the nice comments.
Hi there, love this image. I was wondering if I could use it in my video about Caltrain. I work for Caltrain and have ben asked to make a short video about the history. This photo (Tule fog) would be the perfect image to complement a written piece that is read aloud. Please let me know! socialmedia@caltrain.com
