Anyone willing to admit they don't know everything .. or that at least are willing to learn and try new things.
I myself, do not believe I know everything, and I am always learning something new.... be it in Photography .. or most often, from my kids.
The knowledge I do have I am willing to share and give any Photographic advice(or find the answer for you..and learn myself as well..)
I do offer a couple of courses in Photography..
Photography 1oh1 (basic photography skills and techniques),
and..
D-SLR 1oh1 (the four steps every digital photographer should know and follow)
