Hi guys i really need your help,
I am currently doing a school project on fingerprint recognition and I need to take the fingerprint images outdoor. The finger would be pressed on a glass and a camera below would take the image of that pressed finger. Now the problem here is that there is alot of reflection so I was thinking of substituting the glass with a polarizing filter. Where can I buy the cheapest filter for this purpose and how much would it cost? I saw one for $20 at yahoo auctions.
Thank you for your time.
