I attended a Rick Sammon seminar yesterday here in Huntsville. Rick appeared with sponsorship from the Huntsville Photo Society and Southerland's Camera and, I think, with Canon although the corporate sponsorship was muted.
I was especially interested in his thoughts on HDR photography and I found them to be very enlightening and I'll probably make some small tweaks to my processing workflow. Come to think of it, I shot a scene in HDR yesterday and I've yet to download the images so this should be the perfect opportunity to experiment some.
Unfortunately, I had to leave before the seminar was over so I'm not sure what I missed, but I still got some great tips on composition and lighting and I would highly recommend participation in one of these seminars if one becomes available in your area. The cost was perfect: it was free!
Rick Sammon also conducts workshops at various locations worldwide. There is one coming up, and I don't have the dates, in the Black Hills of South Dakota. The price is $1495.
