The sun will still be at about 19 degrees above the horizon in California. A little high for a landscape but certainly possible. I'm planning on trying to get a landscape type shot of the event somewhere around Cedar City, Cedar Breaks national Monument area to be exact. I'm regretting not taking the time to head to Lubbock Texas and find a cool location of the the event right as the sun sets.
I'm planning on shooting some test shots with various options this week at around 7:30 to see exactly what I think it might take to get the shot I'm working on - I've got 10 stops of Tiffen IR/ND glass, a Singh Ray vari ND and several Lee split ND's. I think to get any type of landscape shot other than perhaps a silhouette (not a bad option with the right subject) will require split ND's and most likely merging multiple shots. I also bought a real cheap
solar camera filter that I might throw on one camera and focus on getting just a shot of the sun itself with a telephoto. Optically it's pretty bad, but then I don't expect the sun to be anything but a ring around the moon ... not much detail.
Landscape photographers take pictures of the sun all the time ... I think the only way you would damage the camera is to use extensive Live View (so those using mirror less cameras might want to be careful) or accidentally over expose the sun by a considerable about.
