Overlapping Visual Fields = More Volume

 This is the first single exposure.   This is another single exposure which is sharper than the first. I overlay these two images in PhotoElements to create the third  image. After this double exposure I will add another layer to create a triple layered image. This is the triple layered image.  In these examples of single, double and triple overlaid images the subject is similar but, the vantage point differs. You and I have a 180 degree field of vision, half of a  circle. Each of our eyes covers about 140 degrees, less than half  of a  circle.  Each eye’s respective field of vision overlaps so that cumulatively we have a 180 degree visual  field.  At any particular second we have only 1 degree of that field in focus while the remainder degrades progressively from the center outward. Because we move the center of our vision about frequently and rapidly  as we move our eyes( more than 100,000 times per day), our brain likes give us the feeling of aggregated focus points. We also call the sequence of focus points foveal saccades.  Our brain wants us to have the feeling that our entire field of vision is comprehended and in focus when it isn’t. Because we have two eyes and two overlapping visual fields with slightly differing information that information can appear fuzzy.  Hold your finger up in front of your face. First close one eye then the other. The finger jumps its position.  We are getting two pictures of the same subject from slightly different angles.  This gives us a feeling of stereo vision. It also gives us fuzzy edges.  The Impressionists  learned that by creating fuzzy edges they could induce a sense of stereo vision. I  learned that if we slightly overlap images that are related but, not from the same angle with even a bigger  angle difference than that of our two eyes, our brain will still perceive the visual  information to have more volume(space) than a viewpoint that is sharper and singular in its source.  Compare the difference for yourself.  In my first two single  exposure photos I jiggled the camera to amplify the sense of motion and reduce edge acuity which also enhances the sense of space and motion.  When I overlap each of these two single exposure images I get a third image ,  an apparent double exposure.  It appears to have both more confusion and a feeling of moree space ( and motion). When I overlap three exposures ( the fourth example) I again increase confusion but also, further increase the sense of volume. After adding more layers I just increase confusion with no enhancement of volume( the effects here vary).  In my final example with my painting, I play with other issues( color harmonies, horizontal vs. vertical contrast, ) as well as the double exposure phenomena but, I begin with the sensation of  overlapping fields of vision.
