Here’s the reason I didn’t take a lot of pictures of the view from our hotel window in Tokyo, and why it took so much work to make one of them look decent:

Yes, that’s the in-room television set that was bolted to a stand right by the window. I worked around it in later shots by covering it with my black jacket, but the correct solution would have been to put a rubber lens hood on the camera and press it right up against the glass (this also works with aquariums, if the glass isn’t curved).

There were three reasons I didn’t use the correct solution: first, I forgot to pack a rubber lens hood; second, it wouldn’t have helped anyway, because the hotel next door was lit up for most of the night, spilling light across the window that would have washed out any shots taken from that position; and third, because my little tabletop tripod wouldn’t have fit on the window sill.
