Well, not the real ones, of course, but those at Hagenbeck’s zoo, anyway.Here’s a nice selection of shots inside the catacombs of the aquarium and the tropical area. The difficulty here is really to get sharp shots – any sharp shots, as it’s quite dark in the building. Another complication has to do with the thick sheets of special glass that protect the water tanks. They introduce layers of refraction, smudge and take away yet more light. So if you go inside the tropical aquarium be shure to boost your iso number quite high and be prepared to labour for each image, both in making it and in post-production. I wonder how much better the situation would be if I had a full-frame camera….
