How to photograph your artwork 

Here are some tips and pointers that will help you improve your art presentations you are photographing  

Step 1. Prepare your art.
Take the painting out of the frame before photographing to prevent any shadows. Also, if the art is frame-less this will help in post-production. Never photograph a picture under glass. It is very hard to get away from any reflections in the glass. The artwork should be on a completely flat surface so that it does not cause shadows to appear on the surface and distort your image.

Step 2. Aim the camera.
Center your art at eye level. Set up your camera on a tripod, pointed directly at the center of the painting. The face of the camera should be always parallel to the art. If your painting is attached to a vertical wall, the camera should be vertical. If the artwork is leaning against a wall or on an easel, the camera must be tilted as well. Make sure the edges of the painting are perfectly square in the viewfinder. If you do not have a tripod, use a table, stack some books, or use anything that can act as a stable surface to rest the camera on. The distance between the tripod and the artwork usually depends on the size of your art. The rule of thumb is to have your painting almost fill the entire view finder, with the camera’s center matching your painting's center, without using your camera’s zoom feature.

Step 3. Lighting is key.
Photograph your art inside using two strong, large diffused lights set up on either side of the camera pointed towards the artwork at a 45-degree angle. This provides balanced lighting across the entire piece of artwork. If you don’t have access to two big diffused lights, take a photo of your art outside when it is cloudy or with an overcast sky. Outside is a natural light and will provide the best representation of your art.Make sure that the flash is off the camera. If not, the flash will produce “hot spots” on your art. 

Step 4. Editing your photographed artwork.
Once you have a few good photos taken, upload them into your software editing program where you can play around with color balance, and white balance, then crop the photo. Make sure the photo looks like your original art.
