HaraldL Posted June 6, 2007 Share #1 Posted June 6, 2007 Advertisement (gone after registration) In scanning slides with it8 calibration it did cause me a lot of trouble to get a nice fading of unsharpness especially in dark areas. In the m8 picture below I took out a detail that would have caused me some sleepness nights. I would prefer a smoother fading instead of this somewhat sudden demarcation. I do think that it would have been nicer with slides. I'm not able to manage this unsharpness right now. What do you think, is this typical for digital files? Is it a matter of profiling? Or do you think it's very much ok and so acceptable? Harald Link to post Share on other sites More sharing options...

B&W Posted June 6, 2007 Share #2 Posted June 6, 2007 I do find your fading smooth and nice. I believe it will be even smother with les contrast Link to post Share on other sites More sharing options...
HaraldL Posted June 6, 2007 Author Share #3 Posted June 6, 2007 And some additional information: C1 LE, no sharpening or noise reduction applied, iso 160. Link to post Share on other sites More sharing options...

B&W Posted June 6, 2007 Share #5 Posted June 6, 2007 Witch profile do you use? Some profiles are less smooth Link to post Share on other sites More sharing options...
HaraldL Posted June 7, 2007 Author Share #6 Posted June 7, 2007 Just standard profiles as supplied with C1 Link to post Share on other sites More sharing options...
lct Posted June 7, 2007 Share #7 Posted June 7, 2007 Advertisement (gone after registration) Matter of lens and aperture IMHO. Did you use the current Summicron 50/2? At f/4 or...? Link to post Share on other sites More sharing options...
jaapv Posted June 7, 2007 Share #8 Posted June 7, 2007 Try one of Jamie's or Edmund's profiles, see what you like best.Although transition of sharpness is basically a function of the lens, different profiles (or different films for that matter) render differently. Having said that, the imprinting of the image on film is a three-dimensional process, as film has a thickness. On a sensor this is two dimensional, as a sensor approaches a plane surface. This makes the transition of sharpness more sharply defined on a sensor. Maybe this is what you are seeing. Link to post Share on other sites More sharing options...
HaraldL Posted June 7, 2007 Author Share #9 Posted June 7, 2007 Matter of lens and aperture IMHO.Did you use the current Summicron 50/2? At f/4 or...? Very well, yes current 50/2. I'm not sure about aperture, I tend to use wide apertures, because of shutter speed and depth of field, so unsharpness. Harald Link to post Share on other sites More sharing options...
erl Posted June 7, 2007 Share #10 Posted June 7, 2007 Harald, I suspect many variables are at play here. My first reaction would be to increase the distance between subject and background to achieve what I think you are aiming at. But of course close control over aperture and other variants are vital as well. Without locking them all down and varying only one, you will never know.
