In 2010, I spent a month on a yacht with other photographers taking pictures of whatever we came across that took our fancy, but we were, of course, looking out for polar bears.
We were there from late July into August, so the time of the midnight sun, where the sun never truly gets below the horizon.
Due to it being so long ago, I don't know where a lot of the locations of the photos were taken because there was no way of recording them. If it were today, thanks to the GPS on my camera, I would be able to say where everything was taken.
