Automation of photo culling is becoming trendy with several project that have started since less than a couple of years, even though it is still far from being mainstream if not just accepted as a real potential advantage for your workflow as a photographer (Link to my other post).
A feature proposed by most project is to cull images where the model has eyes closed. From a technological perspective, this is not breakthrough by any mean. So, it does make sense to propose it. But from a photographical perspective, does it even just make sense?
