COMPARISON
As you can see Both of these photographs lack colour as they have been adapted to black and white which highlights the tones and shadows. Additionally they both have unique pattern that are different as well as reposition of the same objects in the photos. For example in Alfred Stieglitz you can clearly see the repetition of clouds in the sky as well as in Alvin Langdon Coburn’s photo you can see the symmetry of the glass/mirror object which appears to be the main focus of this photograph.
However there are also multiple differences in these photos which can be seen through Coburn’s use of vertical and horizontal harsh lines throughout his image. Whereas Alfred Stieglitz did not use lines in his photography as he chose to picture a realistic object such as clouds which have a relaxed contrast to them as they are not in strictly straight lines.
