These photos were taken four years apart, in 2010 and 2014, but only one season apart, meteorologically.
The March photo is not in black and white; if you look closely you can see bits of color in a couple of places.
Both photos are unusually high-resolution 24MP digital images, which is six times sharper
than movie theaters. They are shown here at about 25% of their actual size.
The U.S.-Canada border runs down the middle of the river. That’s Ontario on the left and New York on the right.
The falls drive humidity into the air, leading to some haze regardless of the time of year at the falls. Generally, winter photos of any location from space are clearer than summer photos because colder air holds less water vapor.
The early-March photo was taken by an astronaut aboard the International Space Station during Expedition 23.
The late-May photo was taken by an astronaut aboard the International Space Station during Expedition 38.
