[filmscanners] RE: Monitor calibration
Thanks Barbara. Well, I cannot boast by the decent video card, since my only system so far is quite old Compaq laptop powered by antique Celeron 330MHz with 192 MB RAM and as you already realized the built-in video card is really weak. To make the display stable I can barely run it at 800x600 @ 75 Hz vertical refresh or sometimes even go down to 60 Hz. Of course, I'm planning in near future to upgrade to decent desktop, but anyway, I don't think the current system configuration might impact the image quality in such way. As about calibration, yesterday I tried different approach from one I followed previously, but which closely resembles to yours: I took generic sRGB Windows profile and calibrated the IIyama with Adobe Gamma utility setting it to 6500K and tweaking colors and Gamma as needed. Overall, the display solely appearance looking good, but this surely doesn't resolve the casting problem which seems to be related to Nikon Color management in NikonScan as I described in my reply to Laurie. Still cannot figure out what went wrong. Not a while ago everything worked fine, NikonScan delivered more or less true, satisfactory colors using it at default color management settings. The only thing was altered is new display, but then it is also seems to be easily calibrated visually... BTW, do you remember what kind of phosphor dots have you chosen during your Adobe Gamma calibration for your Iiyama ?

[filmscanners] RE: Monitor calibration
This is CRT monitor, but I have no idea how they created the profile. For example, the usual color temperature used in PC monitors is 9300K while I certainly prefer 6500K which is much more appropriate for image editing. Bearing that in mind, I have no idea what color temperature they calibrated for. Just an example.

[filmscanners] RE: Scanner calibration
The NikonScan is configured fro Adobe 98 RGB (Preferences/Color Management tab) as well the Photoshop. Well, yesterday evening, for my great disappointment, I revealed that the strong bluish or to be more precise violet cast I reported previously has gone just because once struggling with it I had to tweak analog gain on RGB channels trying to compensate for it, then closing the application the Nikon software remembered that analog gain setting and automatically loaded it once the NikonScan has being re-launched, whilst I though it was cleared off. That was the reason of the cast disappearing, and not my pervious guesses about removing monitor profile. Once I cleared the analog gain settings to 0, the violet cast came back :-(( driving me crazy again. Playing with that more, I figured out that switching Nikon CMS off diminishes the cast greatly making it hardly distinguishable, which means Nikon Color Management caused it with no relation to monitor profiling at all ! Going further, I switched the Nikon CMS On again and set RGB to be Scanner RGB instead of my regular Adobe 98 RGB setting in NikonScan, in order to make the Nikon software not to use the scanner's ICC profiles embedded into the software - that cured the problem again removing the cast, but making certain impact on brightness (the image is a bit darker then). So I inferred that the reason for this violet cast is Nikon's ICC profile embedded into their software. (According to the manual, implying Scanner RGB space in Color Management/RGB tab will dismiss usage of Nikon's ICC profile in the driver, without need to switch off the whole CMS) What really confused me is that fact that a few weeks ago, scanning several rolls of slides and negs with ordinary NikonScan configuration (Nikon CMS is ON) I haven't noticed any unusual color casting over the image. The only changed since then is the monitor... Amy it still be the reason somehow ?

Could it be that this working space is is the problem in that Photoshop is translating the scan input into its working space which is being displayed on the monitor while the scanner output that is not going through Photoshop is being displayed directly in either sRGB or your monitor's default windows or default custom profile? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Alex Zabrovsky Sent: Sunday, April 21, 2002 6:40 AM To: [EMAIL PROTECTED] Subject: [filmscanners] RE: Scanner calibration Well, must admit I cannot complain on the image quality delivered by my IV ED using his default driver NikonScan 3.1.2. Nikon's CMS seems to work good indeed. However, I thought having the scanner calibrated precisely using the Q-60 TI8 slide and appropriate software might create even more precise results, which I would like to compare with driver's native colors interpretation. Frankly, this isn't something pressing me hardly, since the scanner already deliver good results without his profile customization. However I have another issue bothering me a lot. A few days ago I changed my display purchasing new Iiyama VisionMaster 454. It comes with his own setup software (INF file and ICC profile) which I downloaded from their site and installed. into my system (Win98SE). Besides of that, I tweaked the monitor's profile using Adobe Gamma utility and installed it as working monitor's profile. That was the starting point of my troubles. Once I did all that, the scanner started to deliver heavy bluish cast on slides which is easily distinguishable on both preview and scan in Photoshop and to correct it back I had either to play with analog gain feature on RGB or to try to remove that in Photoshop using Curves in RGB channels. That was really frustrating, considering the fact that with the previous monitor I didn't have such problems from the beginning. The friend of mine has recommended to remove this manually created monitor's profile from the system (it is actually started automatically altering the video card's LUT replacing the default Window's values with those generated during my own calibration). Since it is loaded automatically upon Windows startup, to remove it I had to remove the link to this file in System StartUp menu. After I did it, the cast has disappeared indeed for my happiness and the scanned results started to look much more neutral resembling the situation with old monitor. This was relaxing. However, I noticed new effect I didn't pay attention of earlier with new monitor. The scans delivered to Photoshop seemed overexposed (excessive brightness).

[filmscanners] Re: IT8 calibration & SS 120
Jim Thanks again. I will have to try this again tonight. With a four strip there does not seem to be too much room to move the film strip in the holder. I had reasonable success with the Insight 6x24 scan. I will also do as you suggest and try offsetting the frame in Vuescan. Lots to try so that is good, I'm sure I will find a preferred method.
