Daniel that is also true, some people can have their own personal vendetta, and several photographers on there do have haters and people who are jealous, so they are using this great tool to slam a photographer. I have never attended any of these workshops but I will say that one of the photographers on there has been very generous to me about certain information via email.
But what a lot of people are saying about these workshops is this, just because your a great photographer doesnt mean you can teach people. Teaching is a very skilled craft and not everyone can do it. I think that was the problem with most of these workshops and the problem people were having. When this came up in the other forum that was the main topic, teaching skills.
I have recieved emails from beginners asking about a natural lighting class, but I would never in a millions years offer a class and take someone's money because I cant teach....lol
I can offer technical/hands on help but not classroom......
BTW Angelo thanks for the comment!!
