I remember some years ago reading an article by professional landscape and nature photographer in which he said his customers wanted a minimum of 48 Mp quality. I can't remember the details of how he achieved this other than that it entailed a special back on a conventional medium format camera. Eric Stevens |

That's correct - however the same art on billboards may also appear on large poster work for various needs related to the same campaign. -- gmail originated posts filtered due to spam. |

Ok, and before the launch of this new 80MP camera what were people using? Medium format film? And LF. When I scan MF @ 4000 dpi I get about 78 Mpix.

(56 x 4000 / 25.4 )^2 A drum scan of MF or LF will yield a lot more... But they're crap pixels. In large prints, 21MP from the 5D2 is noticeably better than the 52MP from a 4000 ppi scan of 645, and pretty much indistinguishable from the 100 MP from 6x7. (If you blow up 6x7 and 5D2 images excessively, the 6x7 captures marginally more detail, but the grain patterns make the images ugly before you can really use that detail, so it really is a wash. And with the Canon TSE lenses and the Zeiss 21/2.8, there's no problem producing corner to corner razor sharp images.) My usual rant: people cry about how terrible Bayer sensors are and how great life would be with full-color pixels, but in real life Bayer is better than film by about a factor of four, which is flipping amazing. At 12x18, a sharp 5D2 image makes a breathtakingly gorgeous print, one better than anything film formats smaller than 6x7 could ever dream of. To get back to the question, in Tokyo at least, you see LF quality advertising posters all the time. So real people really were using LF, not just the Ansel Adams wannabes. -- David J.

I'm sure it will do better than "siskerize." Maybe we ought to change the name of this group to alt.new.wordsand meanings. It isn't already? Well I thought creating a verb from a noun, a sort of inverse gerund might have been the way to go. :-) Still a non-word though, created for this thread. That said, creation of a large image by use of a mosaic pattern is the technique used by Gigapan to create their massive images. Not all of those are panoramas. Gigapan can use to shoot multiple images of a large subject to be stitched together to form a 1:1 image, or enlargement for a billboard, or similar use. The various uses of "mosaic" in digital have been explored in the SI by Troy Piggins and some others. I have been playing with a Mac program for creating tiled mosaic renditions of JPEGs, "MacOSaix" http://homepage.mac.com/knarf/MacOSaiX/ This is not what is being talked about here. Just a little bit of entertaining fun. -- Regards, Savageduck |
