Paul Strand used geometric shapes and light and shadow as his tools when taking photos.
I like the complexity of the differences in shapes. I can't tell if it's supposed to be portrait or landscape. The light differences give a very nice contrast. I'm not sure if there's a deeper meaning behind this photo though.
I like the idea of complexity this photo gives off. The soft shadows it casts across the rest of the gears from the upper and lower tier show a depth to the photo that would seem almost fake in color.
I like the effect of the shadows and geometric features this gives off. I dislike how many of his photos like this don't really have a deeper meaning and they're just face value.
