how to optimize digital photos from flipcharts

greenspun.com : LUSENET : Imaging Resource Discussion : One Thread

I try to use a Mavica 81 to protocol flipcharts for Minutes of Meetings. The flipcharts contain hand writing on white paper. The resolution is sufficient, but I have problems whith the white balance -> the background is much too dark/grey, the contrast of the writing against the background is too low. I've found out that the contrast with flash is worse than with good light, but I would prefer to use the flash. 1) what actions to you recommend to optimize the contrast of the writing against the background? 2) do you know a software to optimize contrast of jpeg-images in batch-mode? (I have to process large quantities and would prefer to have the optimization automated) Martin
