You would not believe how many blurry images of artwork we see. The simplest solution to this problem is to use a tripod. If you don’t have a tripod, you can also make do simply by setting the camera on a sturdy surface such as a table. A remote shutter release or your camera’s self timer are also helpful because they prevent your hand from jostling the camera at the time of exposure.
For two dimensional work, make sure you shoot your work square on- so the whole piece is equally in focus. For three dimensional work, it may not be possible to get every part completely in focus due to your camera’s “depth of field”. Make sure the most important and prominent parts are crisp and that any parts not in focus are not distracting.
Look through your viewfinder and make sure the focus is as clear as possible. Experiment with the settings on your camera to determine which works the best for your artwork. Take lots of photos and really look at them with a critical eye. Make sure your images are as crisp as possible so viewers can really see your wonderful artwork.
