Prints That Show The Reflective Functions Of Real Objects
When you see an object in person and change the position of the light source, the object looks dramatically different. Think of a sculpture and how different it looks when you change the light source from the top to the right.
Similarly in prints, once the print is made you can’t change the light source and the moment captured reflects the light source that you saw that day.
This dramatic method allows you to see the object in a different depth!
Thanks to Angelo for the find!
