Minimally HDR tonemapped image (hence some minor ghosting).
The larger tannery, and what most tourist guides are referring to when they mention the Fes tanneries. Apparently there are some smaller and quite unimpressive ones around the medina that kids will try to lure you into. Beware, as always.
Photos taken from the shop (it's effectively the only way to see the tannery at all, unfortunately) on the north side. The shop on the west side seemed a bit pushier, although the distinction there is subtle at best.
These coloured vats on the west side of the tannery are where the actual dying takes place.
