After a good amount of experimentation and playing around, I think I've arrived at a good first version of my Zenfolio website. I've managed to setup a portfolio with several galleries for public viewing. In addition to that I've been privately sharing photos with models from some recent photo shoots. Zenfolio has a few nice features to make that happen, in particular password protected galleries.
I'm sure I'll keep adding more material over time, that's expected. And I'll continue to customize and tinker as I see fit!
