Well, a search of the photographer's name didn't bring up any threads related to these images so I'll just stick them here.
Hallopino at DA has done a couple of very nifty Alice photoshoots (mostly props I think) demonstrating either end of the size continuum - considered posting the SW one a while back, but now that he made a GTS one I'll link them all - no process as such in the photos, but Alice nonetheless.
