Digital BW, The Print

Good day all,

Some weeks (or months) back - these years I tend to loose track of
passing time pretty easily - there was mention of a software (a PS
plug-in I think)able to produce effecs similar to different negative
film types. I was wondering if anyone can direct me to the name and
place that sells such a program. I have searched the archieves and
have not turne up what I am hunting.

Thank you for your time,
Bill L.
