2a) This'll be the second gig in a row since getting the *istD where I'll be shooting film. Huh. (Client wants a poster-sized print and wallets -- please do correct me if I'm wrong, but my thinking is that for a 20"x30" print, I probably want to be using a fine-grained film instead of the *istD ... right? I know 300 dpi is a good rule of thumb for most prints, but assuming most folks don't stand that close to a print that large, what's a good minimum resolution to aim for in a poster sized portrait?)
For prints from properly exposed and processed digital capture, 200 ppi can print very nicely indeed at that size. For a 6Mpixel DSLR, upsample by a factor of two using Bicubic Sharper and it will look great.
