Photo No.1: naked light
Photo No.2: with a translucent material between the light source and the object
There is a big different between the two photos, and the biggest one is the sharpness of the photos, being the first one much more sharp then the second as well as the colours more strong and contrasting. I deliberately placed the light on the side of the object so we could see the difference in the shadow the object creates, being much stronger in the first photo.
