Something much more than a painting, but less than a photograph.  This jar is laying on its side toward the lens, laying on thick glass and is backlit against bright light coming through a window directly behind the jar. 

Exposure was F2.8 @ 1/30 sec, and the illumination off the glass and wherever else except through the jar was expected to diffuse to a white and soft texture/tone.

The selected focus was the result of an interesting problem, since a consideration of focus was not only of the glass knob in front, but also of what you could see inside it.  Racking focus back and forth and then thinking about it gives this image.

The flare off the back of the jar is interesting and is different, how???  I'll have to think about it.
