There is a direct correlation between painting on canvas, and the most sophisticated achievements of modern humanity.  In the past, painters developed various "tricks of representation", such as the camera obscura to draw a person's profile.  Between modern painting and photography there is an artistic space in which the digital image and the human artefact inte-relate.  The digital image is absolutely controlled and allow us to intervene using various software programmes so as to rearange the database.  The artist can create a new eidetic pixes image which is closer to the their feeling of reality.  In this way Photoshop, for example, is the modern artist's "trick of representation".
