Sigh, if they "easily beat film" what is point of the newer 4800 dpi
film/slide scanners? A 2700 DPI (ie, Nikon Coolscan III) scanner gets you about 28 Meg per negative/slide. That is only good for an 8x10. Barely, really just a nice 5x7. The 4800 dpi scanners will let you print a nice 14x20. When 9600 DPI scanners arrive, the prints you can get from a negative/slide will be almost life size. Why? Because the resolution stored in a sharp photo is incredible, and good scanners are able to capture more and more of it. A 4800 DPI Scanner gets you about 128Mb per shot. Any 128Mb Digital cameras out there? Forget about 512Mb cameras (which would be needed to keep up with 9600 DPI scanners). Even high end digital cameras (within reach of most of use) are still stretching it to put out a good 8x10. When Digital cameras, if ever, produce more resolution than the best available 35mm scanner, then perhaps the tide will have turned. We are a long way from that day.

Does this mean they have the theoretical equivalent resolution? Are they the equivalent to 35mm? Certainly 8 Mp could beat the pants off of 35mm film, if it was 8 Mpx in a high-end pro camera with a critically fine lens. However, this simply isn't the case when we speak of "8 Mpx cameras." For that matter, the D100, D70 etc. easily beat film, but you will be disappointed with the dinky-sensored consumer cameras that tout 8 Mpx, since a large portion of their resolution is lost due to bleedover and other anomalies associated with the tiny sensor size. |

By my calculations a 2700DPI from a 35mm slide etc. would give something like 3500 x 2500 (give or take), which is about 8.5MPix |

I wouldn't want to tell a customer that I can print a 35mm picture any bigger than that using offset. I would get lynched when they saw the effect -- Petros Ap' ola prin ipirche o Logos |

In that case, the 20D is competitive by Mr. Brummel's standards, it produces a 24 meg JPEG file... -- Skip Middleton http://www.shadowcatcherimagery.com |
