LetsGoDigital found this Photoshop plugin from The Plugin Site which claims to recreate the look of film, lens filters, lab effects and photo papers that are popular in traditional B/W photography, but even goes beyond that.
"The Plugin Site released B/W Styler for Windows, which is another product in the PhotoWiz series. B/W Styler is a Photoshop plugin for B/W conversion, creating traditional B/W effects and styling B/W photos. B/W Styler works in dozens of graphics applications including Photoshop, Paint Shop Pro, Photoshop Elements, Photo-Paint, Photo Plus, IrfanView and PhotoImpact. It supports 8bit and 16bit RGB images. B/W Styler simulates the whole work flow of B/W photography from shooting a photo to processing it in the lab and framing the end result. It recreates the look of films, lens filters, lab effects and photo papers that are popular in traditional B/W photography, but even goes beyond that."
