The document discusses when post-production should be used on photographs. It argues that post-production is acceptable for art as it allows artists to achieve their desired creative effects, but should be limited for factual photography. For photojournalism and documentary photography, minor adjustments for lighting may be acceptable, but extensive post-production could mislead audiences. The document concludes that minimal post-production is appropriate for factual images, while artists should have freedom to pursue their visions, and some editing may be suitable for portraits and commercial photography.
