There are, of course, many additional nuances and tricks that could be added to this initial guide. However, if you are looking to improve your photographs and represent yourself professionally on your public profile page, this is a great starting place.
Hang your artwork on the wall
Find a neutral colored wall (white, black, gray) and hang your work at a height where the middle of your piece will be parallel to where your camera will be—either on a tripod or resting sturdily on a table or other surface.
Light your work properly
Some artists also enjoy photographing their work outdoors when it is cloudy or overcast, as indirect sunlight provides the best lighting. Natural light can be a beautiful way to photograph your work as long as it is indirect.
Adjust your camera and settings
You want to position your camera so that the frame is filled with most of the painting, with a bit of background that you can crop out later. It is important for many juries to see the edges of the paintings to get a sense of scale.
Edit your photos to perfection
While Photoshop still reigns king, Photoshop Elements or Gimp allow basic functions such as color correction, cropping, and other minor adjustments. Lightroom also offers a subscription-based editing program that professional photographers swear by.
