Jan Weis Posted August 6, 2007 Share Posted August 6, 2007 Ok if we look back to the days before DI, when the classic contact print process was used, what kind of resolution were the prints at? most films that go through DI are scanned at 2k?Correct? and the prints contain aproximately 1.5-2k resolution? So I'd imagine that the contact prints reached around 3-4k, Is this assumption correct? Hope I can get this cleared out thanks /Jan Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted August 6, 2007 Premium Member Share Posted August 6, 2007 I'm not sure that pixel resolution is an accurate way to measure the decrease in resolution from a negative to a contact print, not to mention the variable of projection and its effects on resolution. Technically, you'd really want to discuss it in terms of MTF on the neg versus the print. Generally, a projected contact print is similar to 2K digital projection in very rough terms. So yes, maybe you'd say that a 4K to 6K neg becomes 2K to 3K when printed and projected, even lower if an IP/IN is made, but again, projection quality is also a variable, contrast of the image, the print stock, etc. Pixel resolution when describing film is either to make a rough guess at the scanning resolution needed to distinguish between each grain particle in the scan (no reason to scan even higher than that) or what the equivalent digital camera would have to produce to be similar in detail captured, and that's only an approximation as well. Remember, film does not have pixels, so its resolution can't really be measured in pixels. Link to comment Share on other sites More sharing options...
Premium Member Max Jacoby Posted August 7, 2007 Premium Member Share Posted August 7, 2007 In general I find a print that went through a IP/IN stage to be sharper than a 2K DI print. Link to comment Share on other sites More sharing options...
Jan Weis Posted August 7, 2007 Author Share Posted August 7, 2007 Thank you both for your insights. The reason I asked was because I remember reading somewhere in the red department of this messageboard, that since DI was introduced (with 2k resolution) people in this industry have had their standards lowered in terms of quality/resolution of movies on the big screen. So I'm starting to wondering if Kodak & Fuji will start promoting 4k scans in the future, now that HD is becoming used more frequently in studio pictures...Only speculation, but does anybody have a theory they would like to share concerning this matter? /Jan Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted August 8, 2007 Premium Member Share Posted August 8, 2007 4K scanning is becoming more commonplace, thanks to many D.I. companies buying Spirit 4K's, but most of the time they then downrez to 2K for the rest of the D.I. work. An all-4K D.I. will become more and more affordable over time but for now, it's still pretty expensive and slow. Link to comment Share on other sites More sharing options...
