Ansel Adams is an American photographer and environmentalist. His black and white photographs have helped show the wonders of nature through the medium of photography as an art form. One of his many artistic photographs is that of Mount McKinley and Wonder Lake.

In the summer of 1947 Ansel Adams was in Alaska when he took the picture of Mount McKinley with Wonder Lake in its foreground. Having been staying at the ranger cabin at the lake, Adams took this photograph on one of the areas rare cloud-free days. He did this using an 8 x 10 camera recording the image on black and white film.

To compensate for this Adams used a yellow filter on the camera. The result is that when you look at the photograph you see the sky and foreground as much darker colours.

With the filter, Adams is able to highlight the sunlight snow of the mountain as well as the reflective surface of Wonder Lake. As well as this photograph, Adams also took two other pictures. These were the only ones he was able to take as clouds soon covered the whole mountain.

Of the photographs he took of the mountain only this one survived the journey back from Alaska. In taking the pictures, he is said to have thought Alaska as "one of the most impressive reservoirs of beauty and wilderness."
