This is an unmanipulated photo of a glass door knob. I’m mentioning that this is a straight photo as I have photo composition designs upon this door knob in which it will become one element in a greater whole. Time permitting, of course.
The door knob sits in a dark hallway, in this photo lit at the middle of the day by ambient sunlight from both sides. I tried lighting the knob with flash, but the wonderful internal spaces of this object disappeared. So I made due with a time exposure and the dim available light.
