There are several good reasons for photographing both flat and three dimensional art, including cataloging, advertising for sale, appraisal and authentication and for insurance purposes. Obtaining optimal quality images requires attention to some specific considerations. Precise focusing and a steady camera are essential. Use of a tripod is preferable to hand held. Critical color rendition is achieved thru proper lighting and correct white balance settings. Then the image can be finely tuned using various software programs.
Photographing paintings, drawings and other flat art is not as complex as doing sculptures, but it does present some of its own challenges. The art should be evenly illuminated over the entire surface. The plane of the art should be in proper alignment with the axis of the lens to avoid distortion. If the art is framed and/or under glass, other adjustments are in order to deal with glare and reflection.
Creating captivating sculpture images is somewhat subjective when it comes to angles of view and composition, but a bit more demanding from a technical standpoint. A simple non-distracting background is a good start. Another key is to have multiple lights sources to depict the three dimensional aspects of the art and to accentuate or highlight specific surfaces. The shooting angle and elevation should be chosen to reveal the strongest attributes of the piece.
