The Allied air forces continuously took aerial photographs of enemy territory during their missions. Partly due to military reconnaissance measures, but also during bombing operations in order to be able to evaluate hits in the target area. There are also some photos of Cuxhaven here in varying qualities. Some of these images can be found on the NCAP website with the right search terms. Some examples:
