This week’s topic is Abstract Photography. Here is a definition I found which may help you out.
Like abstract art, abstract photography concentrates on shape, form, colour, pattern and texture. The viewer is often unable to see the whole object. The subject of the photo is often only a small part of the idea of the image. Viewers may only know the essence of the image subject or understand it by what is implied.
Often the image will not be a literal view of the subject itself. The subject tends to come second to seeing. The impact of aspects of the subject become a form of expressing the point.
