so far I have read numerous threads, set my camera to low ISO (about 100). I used a halogen work light 500 watts. I have also tried CFL and full spectrum lights, and no matter what type of light I try there is always one problem that I can't figure out how to solve, the light does not spread equally (some areas are too dark and some areas are too bright, areas in the center are usually too bright, and light fades as you move further from the center of the page), moving the light further away from the page helped a little in reducing the glare coming from brightly lit areas as the intensity gets reduced when the light source moves away however the light is still not spreading equally. I think this will require a bit of knowledge in physics and photography. I suck at both. I was thinking of making reflectors made of aluminum foils to spread the light equally but I don't know how to start, and whether it's necessary.
Halogen light tend to produce image with a brownish background rather than the desired white background you typically get when you scan your document using a flatbed scanner. I used ABBYY OCR software and was able to get the desired white background after processing the image however OCR accuracy sucks, so I choose to keep original image and place the text behind the image, getting the desired white background is an issue as well, and yet I am not able to figure out how to fix it, does it have anything to do with camera setting? I have tried almost all settings on my camera and was not able to produce an image with a white background. is there a bright white light I could get? the maximum white light I could find in the hardware store was about 100 watts (not even close to 500 watts), I saw the halogen worklight to CFL conversion tutorial however was not sure whether it will produce a white light with 500 watt.
I took the following two images to demonstrate what I am talking about, one image shows the brownish background I am talking about, notice how the center is brightly lit and the sides are dim. The other image background got lighter as I turned on the flash however it is still not as white as I like it to be. Any help on this matter is appreciated
