When you invert the colors of an image it looks pretty neat. When you start out with an inverted image(like a scanned negative) and invert it the results are way better! According to Photoshop CS2, my processor has hyperthreading! Which is funny, I don't think hyperthreading was around when my processor was made. If that is true, I need to figure out how to utilize it. The only reason I even have a scanned negative is I ordered a transparent materials adapter for my scanner. It lights the slide or negative from behind and turns off the main light. I had trouble with it not scanning over 600 dpi but, after and hour and a half talking to tech support, it works. The worst part: I have no clue why it works now, and I'm a computer science major.

I thought hyperthreading just came out earlier in this year.

I got my PC in mid-December and it reports 2 processors (which means you have hyperthreading).

So, my processor might be capable, but I don't have the additional hardware support to utilize i.
