Guess what this was

I took this photo with my Sony M1 and then used 1 filter in Photoshop to alter it. Two questions, can you tell me what the original image is, and second if you know Photoshop, what filter did I use. As a side note does anybody know anything about digital photo forensics? Email arbynator[at]yahoo.com with info, or leave a comment here.
