A friend of mine said all photographers around here take the same photo from the same famous spot at Lake Louise. But you have to as it is too compelling not to. He also said every photo is unique because the light is always different.
Yesterday I did the tourist photo of the Lake and the Victoria glacier. Today I did it again, a little colder (-20C) but sunny. Tomorrow it will be warmer and clear. I plant to be on the ice at 7:30 AM (dawn) and expect to have a third different photo from the same place.
It is phenomenal how true my friend's observation is.
