Unsurprisingly, photographers themselves are one of the less threatened position. You can read the whole paper here, and according to their calculations, photographers rank 91/702, with just a 0.021 probability of being replaced (us writers are likewise fairly insulated, with a 0.038 probability). However, there are a large number of industries tied to photography that could see replacing in the near future. The study cites both "Camera and Photographic Equipment Repairers" and "Photographic Process Workers and Processing Machine Operators" as near certainties, with 0.97 and 0.99 respectively. That's an extremely high chance, and in the case of developers, the highest possible chance.
