Hi Amore
There's some basic info about SL photography on my website at: http://www.fotoscopesl.com/Support/SLPhotography.aspx
Also a page on SL lighting: http://www.fotoscopesl.com/Support/SLLights.aspx
These refer to technique of course... inspiration is a little harder...... visit great sims and look at great photos!!! THINK about what you want to do in advance. Try to visualise the pics you want to take.... then think about what you need to do to achieve that result. That means... location (backdrop), composition, lighting, angle of view, model(s), props etc etc etc. And then there's post-processing.......
Good luck!
