I think I know the answer to this already. On MF enlarged to 8x10, I have sporadic problems with dust and dirt showing up on the print. On 35mm enlarged to 8x10, seems like every print has a dust or dirt white specs on the print. So, do I assume correctly that 35mm is more prone to this problem than MF? By the same token, is dust on the lens, filters or condensors more noticable on 35mm? If it matters, this was XP2. Thanks in advance. Steve.
