If you are interested in senior portraiture, either improving what you are already doing or adding it as an option in your studio, chances are pretty good that there is another photographer out their that you can learn from.
Laura Daniels is one such person.
Her website, Senior17, is crisp, clean, and extremely easy to navigate.
It contains great senior portraits, instructional information / FAQ's for her seniors on hair, clothing, and makeup that serves two purposes - it will keep her from answering the same questions over and over again and if the guides are followed they will help ensure the best possible image for her clients.
I guess what I am trying to say is Senior17 is a good example of form AND function.
This year I have done more senior portraits than ever, they are fun, they are challenging, and can certainly help make any studio more profitable. I didn't reinvent the wheel, I looked at what successful studios were doing and adopted their good practices.
Be sure to check out Laura's website and blog, I bet you can learn from her too.
