I've been using Tillie's posing stand for over a year! I will tell you that I was not hired by Tillie to create this image, nor was I asked to blog about it. I'm just a big fan and do constantly use it!
It works by placing the stand upon the ground and attaching a HUD which appears on the upper left of the screen - some of the newest features found in 2.0 allows you shrink the hud until you click on it to use it again. I tend to never take it off and use it for all of my photography needs.
The other great thing is that you get updates for life and it is also copyable so I can have various poses in 1 stand or have multiple ones laying around. Seriously look into this for yourself.
