Thanks, I did put curves + in the Effects folder (drag and dropped) BUT it only appears in the Adj. drop down box. I don't see where to get pyrochild.effects.required and don't knoew what box.net is for. Sorry. Addendum: I finally found it and it seems to work now. Thanks again However, the "Negative" preset does not reverse the negative. The "Inverse Luminousity" does work somewhat, but the result is too unclear to be usable, at least on the one negative that I scanned.

I added you curves + to Paint.net and it (after a lot of guessing) got it to appear in the Adjustments list. However, when I clicked on it I got this: File: C:\Program Files\Paint.NET\Effects\Curves+.dll Effect Name: pyrochild.effects.curvesplus.CurvesPlus Full error message: System.IO.FileNotFoundException: Could not load file or assembly 'pyrochild.effects.REQUIRED, Version=3.6.3627.29844, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

Please advise, Thanks

Thanks all.

Sorry, that just inverts colors, not negative to positive.

I am trying to get a look at color negatives by scanning in a multi-function HP printer. I need to convert, or whatever you call it, to a positive so I can determine if it is worthwhile printing (I have a lot of color and B&W negs). Can PaintNet do this? Sorry if this subject has been covered, I could not find it. Thanks a lot.
