1. “Ghost objects” are renderings of forms and shapes as being more transparent than they are in real life; the viewer can “see through” them.
2. “Ghost objects” occur when a depicted object (or person) is present for part of the exposure(s) and absent for part of the exposure(s).
3. The depictions of any ghost objects always disqualify a photograph from Q4 and thus from TCQ.
4. In the 1800s, when long exposures were the norm and the effect would often happen unintentionally, showing persons as “ghostly” presences was a hugely popular branch of photography.
5. TCQ’s disqualification of “ghost objects” applies regardless of how the effect is produced: in-camera; with digital or with film “double exposures”; on a computer; in the darkroom; or any other way.
7. Most of the multiple depictions in an SMP photograph could be characterized as “ghost objects,” because their outline or features are clearly visible but the viewer of the photograph can see “through” the object.
Note: Some lens flare effects are sometimes referred to as “ghosting.” Unlike “ghost objects,” those lens flare effects are not part of the scene depicted. Thus those flare effects may be corrected as per #5 on TCQ’s Allowable Changes list.
