.Did you not have to deal with keystoning ..... ?
. .
I have photographed several hundred paintings for artists. . I find that using a longer focal length and photographing from a moderate distance ensures that there will be no keystoning.
My 100-400mm v2 is my hands-down choice for doing this kind of work.
I typically shoot from a distance of 12 to 15 feet from the subject. . Most of the subjects I shoot are 16" by 20" or larger (sometimes much larger). . You could get the same results shooting from a closer distance if you are shooting tiny little images like 4" by 6", 8" by 10", etc.
I shoot from a tripod, and make sure that the piece I am photographing is hung so that it is perfectly square to the camera. . By that I mean that I want the surface of the painting to be perfectly parallel to the camera's sensor, and the axis from the center of the painting to the center of the lens to be perfectly perpendicular to the plane of the sensor.

"Your" and "you're" are different words with completely different meanings - please use the correct one.
"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "moot point", NOT "mute point".
