What routes do folks suggest for learning how to do people pictures. By this I mean the whole range of portiat sittings along with events. I have for the most part always done nature photography but want to expand my skill set. I have toyed with the idea of volunteering for a studio but not sure if this really works or not (mainly thinking due to insurance/workers comp issues if something happens.. I know thats why nobody can volunteer where I work). As a graduate student I don't always have the most time but am wanting to learn. So.. any suggestions?
