No, that's not the one. It IS a good filter to have though
Most photographers just use a piece of matte black cardboard taped onto the filterholder I believe, but Cokin does make a luxury plastic version in their P line if you want to shell out the money for it.
Check their website (http://www.cokin.fr) for product numbers, I believe they have several versions.
