I decided in picking these two photographers to contrast and compare their work pieces as both photographers use textures, repetition and patterns in an enchanting way. 

Alfred Stieglitz creates patterns and repetition when in the talking of his photos as the clouds create weird patterns and some of the patterns are repeated in the sky creating an abstract look to the clouds.

Whereas, Harry Callahan similarly experiments with these patterns and repetition in his pictures with the abstract pictures he takes of grass and repetition in the photos he has taking of trees being lined up next to each other.

Alfred’s picture on the left contains natural lighting which gives different shades into the patterns of the clouds in the sky making some of the clouds darker and lighter than other sin different regions. Visually, Alfred’s picture is appeared to seem very 2D (flat) as their isn’t much highlight’s of light in the clouds in order for them to appear to be 3D or even clouds moreover, their is a lot of patterns in this picture visually as you can see similar cloud shapes as it appears to be one big cloud with light trying to brake through different segments of the cloud. His purpose and meaning of taking these type of pictures of clouds was that it became an art form for him to take this pictures of the sky and photography quite quickly became an obsession for Alfred as he enjoyed his art form of taking pictures.

Harrys picture on the right was taken from the source of natural light with what appears to be a wide angle aperture being used in taking this picture, this enhances the shadowing and contrast in this image from light to dark tones demonstrating the differences from what appears to be wheat and grass in the picture. Visually the image is contrasted to be 3D as you due to the shadowing giving life to the surface in the picture also, their is repetition in this as you can see their is grass scattered about in the picture giving it a very earthly/ naturalistic appeal to the picture. The context of how Harry would go about in taking his pictures, was that he would just get out of bed and take numerous pictures of things that he thought interested him, this comes across in his picture in my opinion as the picture doesn’t seem to be panned but more of a ‘in the moment’ taken picture.
