sue_deva Posted October 25, 2004 Share Posted October 25, 2004 I recently started using a friend's Super Coolscan 8000 for color and monochrome negative scanning. So far the color negatives have been great, but the B&W scans are TERRIBLE. The bands in the highlights are so consistent and so big that they can be seen in the Photoshop thumbnail preview! Are there any settings that I could try turning on or off to correct this? I have tried running test negatives with every option in place (ICE, LCH, Curves, Unsharp Mask, etc.) and then with none of them selected and it doesn't seem to make a difference. My previous experience with Nikon film scanners taught me that they sometimes band in the shadows. Now it's in the brightest parts. Suggestions? I've included a sample detail of these B&W images. The jpeg crop is about 1/3 the length of the total negative in the horizontal dimension and 2/3 in the vertical dimension. Thanks. Link to comment Share on other sites More sharing options...
scott_eaton Posted October 25, 2004 Share Posted October 25, 2004 Uh, I thought Nikon fixed that problem? I believe it's an issue with the tri-linear CCD array Nikon uses. If you turn off 'single pass' scanning, it usually goes away. Link to comment Share on other sites More sharing options...
Ed_Ingold Posted October 25, 2004 Share Posted October 25, 2004 I assume you know that you cannot use Digital ICE with B&W negatives. The silver image is opaque to infra-red used by ICE, and it's use would exacerbate grain and any banding. Banding tends to occur in dense areas of the film, which would be the lighter areas in prints from negatives. I have never had it occur, but Nikon recommends changing to the single-line scan mode. Banding appears as fine, traverse lines, and occurs only in certain images with high contrast. If it occurs in all images, it may be due to dust in the optics. Dust on the sensor may be fairly sharply defined. Dust on the mirrors appears as broad bands, parallel to the film edge. Link to comment Share on other sites More sharing options...
carl smith Posted October 25, 2004 Share Posted October 25, 2004 That's not the infamous banding issue I'm familiar with which requires superfine scan mode. If that's the full neg the banding is too large and it's running in the wrong direction. Make sure ICE is off, and hope there's no dust in the optics. Also maybe try resecuring the connection but I'm not sure that'd be the problem. Link to comment Share on other sites More sharing options...
