Abstract art is art that does not attempt to represent an accurate depiction of a visual
reality, but instead use shapes, colors, forms and gestural marks to achieve its effect.
The early days of photography centered on true to life imagery i.e. family portraits, images of streets, towns, mansions... Over time photographers expanded their vision to more moody images, ultimately to where photography is today; an all encompassing art form, generated by camera and lens, and producing a vast sampling of imagery from reality to less recognizable abstracts.
This call is about the abstracts; those images that are not instantly identified as that person, that thing, etc. It doesn't matter if you photograph something abstract or create the abstraction through photographic processes. Macro shots, close ups of graffiti, fanciful post processing manipulations or just photographing something at an angle that disguises it - they all work.
