[filmscanners] Re: Silverfast challenge
I had exactly the same experience. I found that using the target transparency that came with my copy of 5.5 (included with my SS4000) to generate an ICC profile gave 8-bit scans that were very close to the original. When I tried high-bit scans I was entirely unable to wrench them to quality as good as the profiled 8-bit scans. - Original Message - From: Bard Martin [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, November 04, 2003 11:44 AM Subject: [filmscanners] Silverfast challenge To this point I've been using Silverfast v. 5.5 with my Polaroid 120 scanner to make 8 bit scans and am generally satisfied. I want to do 16 bit scans, however, and find the product's PDF manual to be totally inadequate when it comes to providing useful information. Apparently, to scan in other than 8 bits one has to use the program's HDR setting. The problem with this is that the resultant scans are horribly off as to hue and value. One cannot correct them, or so it seems, prior to scanning, because all the controls available to make corrections prior to scanning in 8 bit are unavailable (grayed out) in the HDR mode. Wrestling the post-scan images into acceptability in PhotoShop requires heavy-duty Curves and/or Levels manipulation, and I am not yet sure the results will be acceptable for my purposes.

[filmscanners] RE: CanoScan 9900 Dirty Glas Plate
Arthur, Thanks for your reply and tips. Your explanation makes sense. Actually, I have a refurbished $30 flatbed scanner that has the same problem - just much worse. I opened this scanner to clean the inside surface of the glas bed. After leaving the scanner on for a long period of time (1 day or so) with the lid closed the fog appears again. Leaving the lid open or even turning the scanner off helps some. So I guess they used really cheap material that cannot stand the quite high heat produced inside this scanner. Maybe that's why the company who made the scanner doesn't exist anymore...:O Rob -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Arthur Entlich Sent: Tuesday, November 04, 2003 3:02 AM To: [EMAIL PROTECTED] Subject: [filmscanners] Re: CanoScan 9900 Dirty Glas Plate This problem is often due to the plasticizers or mold release agents evaporating from the plastic surfaces from heat after the scanner is built. SOmetimes even the materials used in packaging the scanner may off-gas materials that deposit of the glass bed. These scanners travel by slow ship and often go through considerable temperature changes. First, make sure the fogginess is on the inside surface, by carefully cleaning the outer surface well. As to how much the fog degrades the image, it somewhat depends upon the degree of fog the type of lighting and image sensor, and the thickness of the glass. If there is an area, as you indicate, which is not foggy, you may wish to scan the same material in different areas of the scanner and see if the results are different, keeping in mind that all flatbed scanners have a sweet spot where they scan the best (usually a column down the center of the length of the scanner bed). The bottom line is that scanners really shouldn't have residue on the internal glass surface, and this should be covered by warranty. You might try an exchange and see if the next one is cleaner. Sometimes service techs will end up removing the fog during a cleaning but add other dirt or contaminate the image sensor. These scanners are put together by robots and people in clean rooms (in theory, at least) and whenever they are opened, the risk of new dirt entering exists. Art Robert Meier wrote: I have just purchased a CanoScan 9900. After installing the unit I realized that the glass on which the film/document is placed is foggy. You can see this best when the scanner light is on and look almost parallel to the glass plate. The part closer to the back is more foggy then the other side. Also there is a small clear part so it's definitely not just a property of the glass. Has somebody else discovered that on this particular scanner or other scanners? Is this typical? Does it affect image quality from a practical point of view?

[filmscanners] OT: Pentax *ist D
If anyone has had any experience with the new Pentax Digital SLR, please contact me off the list. I had a look at one today, and just checked the specs. On the surface at least, it looks like the sort of thing I was hoping Pentax would make - a camera that lets me use my existing lenses, and provides about the same number of pixels as scanning film with my LS30 (about 3000x2000).

My questions are *Does this documennt still hold the sharpening? *Should I have done resizing before sharpening? I do not have backup of color corrected images.

[filmscanners] Using Vuescan and a Faust IT-8 target.
I am trying to profile a film scanner (a Nikon LS-2000) using a Faust IT-8 target. I am slightly confused by the following instructions: 1) Set Input|Scan task to Profile scanner 2) Rename IT8 description file scanner.it8 Actually I understand the first line , but it is the second step that confuses me. where do I name the the IT-8 description file? This seems to imply one of two options/ A.) that I scan the file the target first (as a RAW file?) and then open it back up in Vuescan and proceed through steps 3 to 7. Or... B.) Go to Output and name the TIFF file there. secondly I can download a set of numbers for this particular target set. I understand that I should somehow plug them in, but how? The manual simply isn't clear and your help will be much appreciated so thank you in advance. Cheers! Ellis Vener http://www.ellisvener.com One test is worth a thousand experts' opinions. - Capt.

[filmscanners] RE: OT: Resizing without resampling
Preston, I do agree with your reply; but I think that your articulation might be clearer if you had said: Most people recommend resampling before sharpening instead of Most people recommend resizing before sharpening since resizing and resampling are two distinct operations which are not necessarily connected. Resizing without resampling only changes the effective resolution but not the acutal resolution; whereas resampling changes both. It is the latter that impacts on the results of USM - not the former. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Preston Earle Sent: Wednesday, November 05, 2003 9:01 PM To: [EMAIL PROTECTED] Subject: [filmscanners] Re: OT: Resizing without resampling Nagaraj, Ramesh [EMAIL PROTECTED] wrote: After sharpening, I am using Image size-Document size(with Resample checkbox off) to change the width, height and resolution without resampling.

[filmscanners] RE: OT: Resizing without resampling
You are correct; it should not effect the sharpening per se, although it may alter the perception of the sharpening. When you resize without resampling, you are only changing the effective resolution but not the actual resolution. In short if you make the image larger, you are not decreasing the number of pixels in the file but merely spreading them out further so as to have fewer per inch but not fewer in the image file. When you resample, you are changing the overall number of pixels in the image file. Typically, such resizing or even resampling does not lessen the sharpening making it softer for all practical purposes; but resampling can and often does create artifacts which resizing alone does not. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Nagaraj, Ramesh Sent: Wednesday, November 05, 2003 12:19 PM To: [EMAIL PROTECTED] Subject: [filmscanners] OT: Resizing without resampling I have document that is color corrected and sharpened.
