I want to practice sculpting heads, and I was hoping to find some good references of the same person from multiple angles. Do any of you have recommendations? Posespace seems to work okay, but seems geared more toward figurative work. I just wondered if there were some options that I was missing. In the past I have tried to use celebrities, since it is easy to find lots of photos of them, but something with all the photos gathered together, with photos from all angles would be great. Any thoughts? It seems to me that there could be room for a crowd-sourced collection of free artist reference here (especially if we are just looking at portraits, since people would be more willing to put up their face online than nudes), but I don't know of anything like this. If 20 sculptors took photos of three friends each, we would have a nice start to a collection.
