About the Whiteboard Photo Cleaner
Photos of a whiteboard after a class or meeting usually come out grey, tilted and full of glare. The Img Stop Whiteboard Photo Cleaner finds the edges of the board, straightens it and cleans it up so it is easy to read.
Glare, shadows and grey cast are removed, the board becomes pure white and marker colours look bright. It also works on blackboards and handwritten notes. Save each as JPG or PNG, or put several photos into one PDF of lecture notes.
