Question regarding art and pictures.?

You can set your art in the shade, like on a porch. To avoid having glare off the surface, the light cannot be shining on the work from the camera, but instead indirectly, ideally two light sources on either side from 45 degrees. Hang up a piece of black, non-reflective fabric behind the art. Do not include any more background than you can help. Set your camera's color for shade and make sure that the back of the camera is parallel to the plane of the work. Look through the view finder and be sure the edges of it line up with the edges of the picture. This makes sure you won't get distortion from shooting from an angle. If it is a bright day, you shouldn't need a tripod, just a steady hand. It will also help to zoom back and stand fairly close, rather than standing back and zooming in. I hope this helps. I use Photoshop for editing, but it's far from free. Can't help you there. Good luck!
