If you take a picture of a scene, you have taken the picture. Right? Is there a need to take another pic of the scene or object? The answer to the question is, it is surprising how many different photographs there are of a scene or other subject when taken at different times or by different photographers. There are an infinite number of photographs available.
Look at the photographs of the Fries dam in the gallery below. All of these pictures were made at roughly the same spot over a number of months. They were all made by me and with the same equipment. My point is to illustrate how different seasons and different times of day result in very different photographs.
It is a common misconception that a photograph is a photograph. Many factors go into the production of the photograph: The vision of the artist (the photographer), the focal length of the lens, the lighting conditions present when the photo is made, the vision of the artist, the aperture of the lens, the atmospheric conditions present, the vision of the artist, the camera position, the shutter speed used, the type of medium used to record the photo (different types of electronic sensors, varying films), the vision of the artist, post-production decisions. I could go on and on, but please note that I emphasized the vision of the artist. The artist is the one who puts all of these factors together and produces the photograph.
This album is on my Facebook page and I plan to update it frequently with pictures of the Fries dam so that you can see how wildly different photos of one dam subject can be.
