PHOTOGRAPHIC FLAT ART
When you photograph anything flat, like this ancient cave painting in Baja California, Mexico, make the back of your camera -- i.e. the plane of the sensor -- as parallel as possible to the subject. This helps maintain depth of field. If the light level is low, as it was when I took this picture, and you can't use a tripod, a small lens aperture may not be possible because that will make the shutter speed too slow for hand-holding.
Therefore, the only way you can show all of the detail in the subject with tack sharp clarity is to angle the camera such that the sensor is as parallel as possible. Then you'll have all the detail you want at any lens aperture.
