Andre, It may be that the 8000 has a different driver/software package than the 4000. When I use the "positive" setting for B&W negatives, the image will look very light when inverted in Photoshop. The default algorithm Nikon uses gives tremendous shadow separation -- probably too much. I have tried raising the histogram middle (gamma) in the Nikon tools palette and comparing that to doing the same thing in Photoshop, and I'm not completely sure if there is any difference. I think I may have detected a little, but it's not dramatic. Nonetheless, just in case there is an advantage, I do raise the middle of the curve on the Nikon tools histogram graph in order to compress the shadow tones. I tried, again, comparing the "negative" setting to the "positive" setting and found that to get the highlights in my B&W negatives I needed about -0.6 analog gain adjustment. (This varies with each negative.) However, the shadows were blocked in the negative I just tried. Even though the blackest black read only 96% in Photoshop, there were masses of 96% where in the "positive" scan there was lots of detail & information. What I look for is a 14 bit scan that has enough room off the ends of the histogram that when I move the PS levels histogram slider in with the alt key held down to tell me what pixels are where, I get no pixels lighting up at 100% or 0%. I want just a hair of space to be sure nothing has been lost. So, with a scan like that, even if it looks too light when inverted in PS, the PS image adjustment curves brings the values closer to what I like (and what looks more normal), and there are enough g/s values left to do any manipulation I want and still have a full 256 levels left by the time I get to the printing stage. (I do now use the Nikon tools histogram to pushed up the middle of the curve to compress the dark tones.) (I have not yet experimented with other than the Nikon default profile in the "preferences" section of the driver.) Paul http://www.PaulRoark.com ________________________________________

did you use the full range setting? IS there a full range setting in that scanner? jerry Andr\ufffd Vallejo wrote:
