It's hard to think of another wildlife documentary from a single photographer that is shot as beautifully as this from beginning to end. Charlie Hamilton James documents a year of his life filming the otters on the River Torridge in Devon, following in the footsteps of Henry Williamson, who documented them in his novel Tarka the Otter at the same spot a century earlier. This photographic essay is a labour of love by someone who is clearly as in love with the area, the changes in the seasons, as he is with the otters themselves. His own commentary on his progress in filming them, which conveys his joys at the family's successes, and his anxieties at the their apparent upsets, is extremely informative and makes the perfect fit with his photography. It's an absolute joy to watch.
