VISION AND THE TECHNIQUE OF ART. 47 



CONCLUSIONS. 



1. Every object in space is imaged on the retina with character- 

 istics of form, color, accentuation of line and chromatic edges, due 

 to its particular position relative to the focus point. 



2. These characteristics, of which the observer may or may not 

 be conscious, suggest to him the position of the object in space relative 

 to his fixation point. 



3. The reproduction in a picture of these characteristics of images 

 of objects causes the depicted objects to appear in the same relative 

 positions that they occupied in space. 



4. A pictorial representation of nature to be technically satisfactory 

 from an artistic point of view should be similar to our subjective 

 impression. It should not attempt to reproduce actuality. 



5. Our subjective impressions are, in their general character, simi- 

 lar to the pictures we receive on our retinas while holding one center 

 of focus. 



6. A pictorial representation of nature to be technically satis- 

 factory from an artistic point of view should be similar in its general 

 characteristics to the pictures we receive on our retinas while holding 

 one center of focus. 



7. An intellectual knowledge of the characteristics of the retinal 

 image of objects not at the center of focus helps one to become visually 

 conscious of such characteristics.
