[Hidden-tech] Scanning Photos in FCP

[Ada O Shaw]

I'm scanning some photos for multiple purposes - primarily for use in a documentary - HDV specs 16X9 - but I would also like to be able to blow some of the up for publicity prints or posters. 

I think 72 dpi at the dimensions of my QuickTime files is the most FCP can take advantage of but does anyone have recommendations for a workflow/resolution that would be suitable for both purposes?
