2,5 half years ago (more close to 3 actually) I was testing out some new software that I never used before, in the specific a new render engine , Keyshot, with which I fell in love since. I ended up working (without really wanting or planning it) on my very own head and I was extremely amazed by the results achievable with KS when It came to skin rendering. Other softwares used were Photoscan for the rough pass on the head, then Mudbox for sculpting and painting.
