How to take a photo of painting?

[Konstantin]

No flash usually takes the sharpness and the picture is hopelessly corrupt.

This is not the sharpness goes away, and the camera makes a long shutter speed (although this is sometimes unnoticed), and the time of shooting slightly trembling hands. And it gives blurry picture, which apparently can be perceived as sharp. I always try to take pictures without flash, more accurate colors. Just in time to take firmer hold the camera.
