I am french artist and I am passionate about optical art. I'm working on three new pictorial concepts: The anaglyph painting, the stereoscopic anamorphosis and the afterimage in painting. I want to start an article on the afterimages that we can see with eyes closed, hence the philosophical interest in my approach.
The afterimage in painting:
- Definition "Afterimage" or "remanence":
Property of a sensation, in particular a visual one, that remains after the disappearance of the stimulus. A stimulus is a factor that has an effect on a cell, on an organ, on the organism, causing a muscular or nervous response. This art relies on the phenomenon of retinal persistence, which allows the brain to "virtualize" paintings "in positive" and see what they represent when looked at on a very contrasted surface. Click on the picture, concentrate on the small white dot for 30 seconds and keep your eyes fixed on a plain surface (for example: a white wall) for 10 seconds, or simply close your eyes for 10 seconds. Your mind, by the use of "afterimage", will reveal the face of the person on the portrait.
