I could not live (professionally) without Grain Surgery. It's expensive but worth every penny. It's actually the only really expensive Photoshop plugin that I have. And the reason I bought it it's that I found nothing else that can do this essential job so well. I wish Adobe could incorporate this technology inside Photoshop. The grain filters of Photoshop are like dinosaurs compared with GS. I forgot the best thing about it: bloody easy to use. Never had to read the help files once.
