I just wrote a huge article on my blog about lighting techniques. I was hoping I could just copy and paste it here as I think it would be valuable info for everyone. Normally I would just rehash the post into a forum post and add the images...but there is a lot of images including diagrams.
So, if it's okay with the community... here is the link to the article:
LK1:1photoGRAPHICS: Lighting Setups with Caitlin @ The Photographer Studio.
I go over everything from a basic one light setup to a 4 light setup and different combos there of. While I'm not the most experienced in posing it could be valuable info to those that could use some lighting help.
