10 Aug 2009	Vishwasrao Salunkhe	Hello , thanks for this beautiful code, This seems to be good. I ahve tested it on no.of images . I am getting mixed results. For grayscale images out of 20 images 10 gets brightened but remaining are as it is. what will be reason. thanks in advance.
10 Aug 2009	Divakar Roy	Maybe those not-brightened images won't look better if brightened. Try sending me email and then you can send me the images, will look at those. Thanks for being part of the feedback community.
