The following pictures were taken on 2 missions to Hamburg, Germany, on 6/18/44 and 6/20/44.
I am not sure why the pictures appear to be dark, as they should be daytime photos.  Perhaps it had something to do with the exposure or developing technique.  Or, perhaps, these photos have changed due to age, since they are some 47 years old.
   I thought that perhaps the photos were taken on some recon mission rather than on the actual bomb run, but you can see bombs exploding, and in the third photo you can actually see bombs falling, which suggests that they were taken on the actual mission.
