Whiteboard Photo uses sophisticated image analysis techniques to remove the background and bring out the colors in the photo. In addition, Whiteboard Photo provides geometry correction that even takes into account spherical distortions from camera lenses. No image editing software can do all that. No, but it might help. Most digital cameras can handle fairly low light conditions, but it is hard to steady the camera without blurring photos.
Some cameras are better than others, though.
An inexpensive table-top tripod can help keep photos crisp. Whiteboard Photo can handle dark images with no problem. Whiteboard Photo can even use photos that are almost entirely black and find the whiteboard contents. With copy boards you have to remember to turn them on before you start writing and use special pens. For less money, you can capture any whiteboard, flipchart, or blackboard in your building after the fact.
