If you have even the slightest interest in selling your photography you need to read the article "How should I price my photography?" by photographer extraordinaire Jodie Otte.
In the article she gives a wonderful breakdown of what we should consider when determining what our pricing should be. It is a few minutes worth of reading that will not only educate you, but has the ability to put thousands of dollars into your pocket.
After you finish reading the article you will want to head over to her website and look at her jaw dropping images. One of the things you will notice is how naturally lit her studio images look, and no she doesn't have huge windows or a bank of skylights, she uses the same strobes and softboxes that you and I use, she just uses them much better.
You can check out her book "Studio Lighting Naturally", in it Jodie will teach you how to achieve natural studio lighting along with tips on photographing babies, expecting moms, and much, much more.
