High res 8x10 scan sample, anybody?

[Sizam]

Could somebody(s) post some samples of high-resolution scans from 8x10, color or B&W? I'm curious what you can really get out of a high-res scan so maybe a small 100% crop and a full sample if you will.

Thanks!

Fuji Pro160S scanned at 2000SPI on a Howtek 4500...

Here's a B&W example. Tmax100 scanned at 2000SPI. Crop is at 100% (excuse the lack of any merit in the subject matter - this was a test shot to compare 4x5 and 8x10 and find out at what print size the two showed differences).

Don, what size did you come up with?

[Sizam]

Impressive, and both those are 8x10 samples?

[john borrelli]

Extremely impressive!

[Don Hutton]

Those are both about 8x10: at 2000SPI yields about 19500 x 15500 pixels. The B&W at full size and printed at 360DPI would be about 53x43". The crop would represent a 2.6 x2.1" piece of that print... I can't remember the exact size of the color crop because I did it some time ago.

Thanks for the extra info.

So now I'm a little concerned, here is a comparison of the color shot with a shot from the Hasselblad H3D-39II (unsharpened):

Seems like the 8x10 edges out the Hassy but not by very much, or am I missing something? I was hoping for at least 4x more resolution in an 8x10 scan, virtually equal really takes the wind out of my sails. Feel free to call me and idiot and say there is a substantial difference.

The crops are almost comparable size in a pixel sense - what you're missing is that the 8x10 scan crop is from an image which is 19500x15500pixels, whereas as the Hassy is only 7200x5400 pixels - so is you printed both at 360DPI, the scan would produce a print of about 53x43 inches with about the same level of detail as a 20x15 inch print from the Hassy... The print from the scan would be 7 and a half times bigger than the print from the Hassy. Apples and oranges. Even then, I think that the scan crop shows more detail than the Hassy crop - there's no texture in the bushs on the Hassy crop.

Here's another crop from the same scan - this would be a 1.5 x 4 inch piece of that 53x43inch print... You can't even discern these guys on the Jpeg of the whole scene, but they're there (about 2/3rds of the way up the beach).... BTW, both scans are completely unsharpened.
