First of all, learning to sculpt in for example Zbrush is not a few-years process. In fact it goes very fast-I've tried it-and it is not only for computer geeks.
However, sculpting in Zbrush still requires traditional sculpting skills, knowledge of anatomy, some talent,and of course some traditional sculpting experience.
If my statement is not true, then there would be no bad Zbrush sculpts, and I've seen a few - believe me.
That was the reason I give up on Zbrush - I had no traditional sculpting knowledge and turned back to sculpey to get some-one day I'll go back
True, there are few benefits of using Zbrush that make sculpting easier:
Automatic Symmetry
Masks (prevent to touch unwanted areas of the sculpt)
Magnification
Any part of sculpt can be modified at any time during the process
Parts (tools) are "reusable" and can be used in other sculpt
Final sculpt won't crack in the owen
Final "product" can be in any scale you want-Just imagine same figure printed in all needed scales !!!
So, digital sculpting for me is still sculpting, just with new media.
In one word: I'm not using digital sculpting (yet) not because I could not learn how to use the software, but because I do not know how to sculpt !!!
Forgot to say: 3D scanning mentioned in previous posts, and then 3D printing is more similar to live-casting, only difference is that live cast is always 1/1 scale, and with 3D scanning you can get any scale you want. But that is NOT sculpting, and not art, that is pure use of technology
