I found out about focal length quite some time ago, Poser 4 probably, after i bought Sisters from Dalinise and Stormi...they looked way awesome in their product pics, but when I rendered them, they looked like some weird alien women...I was way disappointed and thought I bought a faulty product. They worked with me for quite awhile until , viola, one of them asked where my focal length was set at. It was default 50mm ... I went to 105 .. and wow .. you can't even begin to describe the difference.

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
