If you really don't have too much spare time, and you've been tired while you returned home, then read a thick software manual up to more than 1000 pages must be a great burden.
Daz Studio saves a lot of time. I don't have to learn complicated skills to make 3D models or textures, which usually takes an in-house designer up to more than 1 month's work. Just several simple steps, combined with some powerful shaders such as uberenvironment and elite human surface shader, the dreams of making beautiful and realistic 3D character soon come true.
Thanks for Daz Studio, and I bet it worth as you try it, not to mention it's still free.
