I love cinematography. I is the science or  of motion picture photography. Are you interested in it?
I don't know much about it. What Is cinematography pretty much movie making art?
Well usually a lens is used to repeatedly focus on light reflected from objects.  This turns it into real images in the camera and it creates multiple images.  It is just fascinating.
This is amazing! I'd like to try it some time, the whole process is so inspiring.
It really is.  With an electric image sensor you can see each pixel and then it is sotred for display or processing.
