Re: LS5000 and 4000 dpi scanning

Depends on what you want to do with the scan. If you are enlarging to print, then i scan at 300 ppi X film frame size X enlarging factor and then to the next highest 2x multiple of the sensor ( never above sensor resolution), eg - 10x enlargement of 1 inch frame = 3000 pixels - scan at 4000 ppi and ...

Re: LS5000 and 4000 dpi scanning

Are you interested in the maximum sampling or the resolving capability of the scanner ? 4000 spi is correct for the sampling #. i have seen numbers around 2700-2900 ppi for actual resolving capability of the optics + sensor. Have a look here http://www.scannerforum.com select comparisons, class 3 - ...

Re: Autofocus problem with Nikon LS4000 and SF200

i very seldom see the focus point in the center with the Nikon. It is usually on a high contrast edge in the image.

Re: Lamp Control on Nikon 9000

i do not use the Leopard version ( i assume ME is there) , but wouldn't the multi-exposure feature address what we used to use the "led lamp on time control" for ?

Re: Autofocus problem with Nikon LS4000 and SF200

The Nikons have a very narrow depth of field. If the film is not within about +/- 5 Nikon focus units of the focus point parts of the image will be out of focus slightly. Many slides will be this way. Try manual focus on those slides and see if it helps. If not, then the slide is not flat enough and...

Re: depth of field with Nikon LS 5000

Any issues you have with the DOF and the CS5000 will not change. It is a function of the hardware Nikon uses. At best, you may be able to pick a better average focus point. The real issue is film flatness. There are options (3rd party) for using anti-Newton glass in the FH3 film strip holder. If sli...

Re: Post-Editing Options for HDR Output

Regarding - You will realize that 48 bits HDR pictures created with SilverFast will look underexposed (they are not underexposed, it is only that the portion of the histogram were the information is located can not be displayed by your monitor), Last time i checked this was simply from no gamma bein...

Re: Multiexposure not working

Perhaps the information that Evan was missing was that the multiexposure option does not change the overall exposure for the image, but through a combination of taking advantage of the 2 sample passes, reduces the random noise from the hardware and by taking two different scans adds in extra data va...

Re: B&W Negative Scans

This is chromagenic B&W ? It may just be the dye clouds. Do you get the same response with other films (color neg films) ? The trouble with scanning negs is that the dark areas, which have most highlight detail, are hardest for the scanner to detect above the noise limitation of the sensor and e...

Re: Prescans just a mass of pixels

find a different cable and start with that.
2nd check the power supply to the scanner is good ( input/output voltage on the xformer are correct)
run then canon scan software and see you get the same result.
If the canon software is ok, then there is likely an issue with the install for SF on the Mac.

Re: B&W Negative Scans

One of the issues may be the resolving ability of the Epson scanner. If i remember correctly, most of the scanners in that era could resolve somewhere around 1800 - 2200 ppi . Also, the Epson scanner driver may be including some sharpening on its own. i don't know how to turn that off. Try scanning ...

Re: Scans not matching original

Did you use Monaco to profile the scanner for the specific paper and ink that you are using ? Make sure the ink has dried for 24 hrs before you profile. i have seen slight color shifts from this. Also, make sure the scanner has equilibrated for 20-30 minutes before you scan. Even with all of that ok...

Re: LS5000 and 4000 dpi scanning

i remember some tests done across a variety of scanners (CS4000 to drum scanners) and the resolving capability of the CS5000 was around 2200-2700 ppi. So any scans at above that should show some artifacts. From the images, it does look like the edge contrast is higher for the Silverfast scan.
