I found this information about the difference between real abstracts and altered abstracts
Abstract photography is a process of using colours and patterns combined to create an image, with no true meaning or no clear subject involved.
Abstract photography is not necessarily going to mean the same thing to everyone.
Abstract photography leaves more to the imagination and helps us concentrate on texture and colour rather than the whole subject.
Abstract photography is photography, which contains a design of patterns, or shapes where the identity of a subject is not easily evident.
Altered Reality Photography is a unique blending of photography and impressionistic art.
Begun as a Polaroid photograph, the Altered Reality is manipulated using various tools while the surface is still pliable.
Swirls of color and texture transform the realism of the scene to an altered view.
Altered Reality means the alteration of a scene or subject so that it is obviously unrealistic.
The image being altered must have been taken with a camera.
The alteration may be done with an image editor (e.g. Photoshop) or by any other means at the photographer’s disposal, as long as the result depicts a significant deviation from reality.
So just let us go abstract this month in whatever way!
A (wo)man should hear a little music, read a little poetry, and see a fine picture every day of his/her life, in order that worldly cares may not obliterate the sense of the beautiful. (free to J.W. von Goethe)
