I for one would love to be able to take the one you are offering above.
Honestly, I would also like to take one on glamour photography.
I'm also interested in location shooting, as in how to light with portable lighting.
I myself have a 580EX and a 420EX. I know the 580 will control the 420, but I just can't seem to get them to jive.
I'm probably making it more difficult than it has to be.
I will keep my eyes peeled looking for any of your workshops.
Feel free to drop me a PM and let me know what you have coming up too.
Thanks.
