Hi I have a client that wants some photos taken of thier family and the enlargments need to be pretty large, 30x40. I was thinking about using fuji npc 160 rating it at 200. Does anyone think that there may be a problem with grain with this film at this size of an enlargment. I have gone as large as 16x20 with no problem with NPC but I worry that this large there might be trouble. Any suggestions on a different film or should this be fine. Thanks!
