Trumpet (2 of 2) (IMAGE) Swedish Research Council Caption This image is illuminated in 75 degree angle, and the camera is placed oppositely in 75 degree angle. The light does not penetrate into the paper but is reflected on the surface. The light therefore does not reach the inks, and the light that reaches the camera only carries some contrast information from the image surface. This is exactly the effect that comes from being blinded by a glossy commercial that is held in the light.
