Printing B&W Photos With A Color Ink Jet--A Perrenial Problem
Q. Thank you for an interesting and informative department each month. Perhaps you can give me some advice on two related printer questions. The first: How can I get a good neutral black when printing black and white on my Epson 1280 on Epson Premium Glossy Photo paper? My black and white photos often have a slight magenta hue in the dark, black areas (not fringing, the whole black area is slightly magenta). This does not appear to be an overall color shift, it seems limited to very dark areas only. I have tried converting color photos to black and white by using the gray scale in Photoshop and printing with only black ink, which produces neutral blacks but rather flat-looking photos. I have also tried desaturating a color photo using Hue/Saturation in Photoshop and printing it as a color photo. This produces a better looking photo, but contains the slight black pollution. I find using the Hue/Saturation set to only 5 percent saturation gives an interesting black and white image which most people like, but is not true black and white. It does sort of hide the pollution, though. I have also tried adjusting the magenta setting in the printer software downward a little. This reduces the effect, but also gives a slight greenish tinge to other dark, but not black, parts of the print. If I turn the auto color control in the printer software off, the print will be decidedly greenish. While I imagine that the effect is present in color photos, it is too small to be noticeable.
Second question: What is the best way to make black and white prints up to 13x19"? Is there a newer printer that does a better job on black and white--maybe a 2200? Or, how about using one of those third-party black and white ink sets that only print black and white and dedicate this printer to black and white and buy another one for color? I would appreciate any guidance you might have to offer on these topics.

A. The problem with trying to make neutral-toned black and white photo prints with a six-color ink jet printer you described is pretty universal. It is due to the fact the printers are mass-produced consumer products and obtaining an exact balance of six colors of ink to produce neutral blacks and grays is like trying to balance a cue ball on the tip of a pool cue, or better, balance a marble on the point of a pin. It is as much due to the fact the inks are not 100 percent exact in density as it is a mechanical problem beyond the printer's precision.
The Epson Stylus Pro 4000 printer is better, and should be with a price of $1800, but it still is not a really good solution because pigment ink prints made with colored inks are subject to metamerism--they shift in tonal color quite obviously as the color temperature of the light illuminating the print changes. This problem also applies to the Epson Stylus Photo 2200.
The best solution for printing black and white photographs with an ink jet is to convert an ink jet printer to use all-black ink. I recently finished my second article on this subject which appears in the February 2005 issue of Shutterbug on page 44 (you can also find this article on our website at: www.shutterbug.com). It covers a number of simple to sophisticated black and white printing options. You can get a bit of an idea of what is involved and available at the MIS Associates website at: www.inksupply.com.
Personally I have converted a "retired" Epson Stylus Photo 2000P to use all-black ink and am very satisfied with the results.

Can "Digital" SLR Lenses Be Used With 35mm Film Cameras?
Q. I'm interested in buying both the Nikon FM3A and the D70. My question: Is the D70 kit lens--the AF-S 18-70mm f/3.5-4.5G ED-IF DX Zoom Nikkor--compatible with the FM3A? I'd read on another website that it is compatible with AF-S Nikkor lenses.

A. The Nikkor AF-S 18-70mm DX Zoom lens is not compatible with the FM3A 35mm film camera. DX lenses are only compatible with Nikon D digital cameras. Essentially the same is true with other camera brands of "digital" SLR lenses made for "APS format" digital SLRs; they do not have the area coverage for use with a full-frame 35mm film SLR and are thus not compatible.

How To Convert Digital Camera Raw Files
Q. I am about to go digital and I just re-read your article concerning the SilverFast raw converter. This article was written before Photoshop CS. Would you still recommend SilverFast DC Pro over the controls within Photoshop?
Judy Grose

A. Since the report you cited I have had numerous occasions to compare results converting digital camera raw files using both the Camera Raw utility provided by Adobe in Photoshop CS and now also in Photoshop Elements 3.0, with LaserSoft SilverFast DC Pro. My opinion based on the results of that comparison is that LaserSoft SilverFast DC Pro provides the possibility of obtaining a much cleaner, more accurate interpretation of the subject in color as well as better control of sharpness and both global and local contrast than can be achieved with Photoshop's Camera Raw.
Whether SilverFast DC Pro is worth the extra investment depends on how demanding a photographer is in expecting precise and accurate color reproduction with high fidelity to the subject. Personally, I find SilverFast DC Pro worthwhile, but I am sure many others will be satisfied with Photoshop's Camera Raw as good enough; but to me it is the difference between acceptable and excellent, and I prefer excellence.

Dealing With Making Scanners & Printers Work After A System Upgrade
Q. I have a couple of questions re: my transition from Windows 98 to XP. It has been a rough transition for me to get everything up and running on this new OS and I keep finding my options seem to be much more limiting with XP. My previous CD burning software (Roxio) had the option of choosing your own burn speeds. Many computer tech people have told me over the years to burn image files using slow burn speeds for more permanence. My current software for my CD/DVD burner (Sonic's RecordNow Version 7) which was bundled with my Dell does not have the option of choosing a burn speed, instead the software chooses for you.
Do you think this idea of burning at slower speeds still holds true with the newer burners, both CD and DVD or do you believe the software I have now will be sufficient? I could opt for a more advanced version which would give me this choice, but do you think it is necessary with the new burners?
My other question pertains to my CanoScan FS 2710 35mm film scanner. It uses a SCSI connection and before I tried to install the old SCSI card into my new computer I called Canon and they told me that this particular scanner is not compatible with Windows XP. Another bummer. Do you believe this to be true?
I have already told you about my frustration with the newer printer drivers for my Epson 1280. There is no choice available for selection of printer resolution with the paper I use most, ColorLife Photo Paper. "Best Photo" is the only choice which prints at 2880dpi. I believe the reason Epson did this was to make more money on purchases of ink jet cartridges as the 2880 setting sucks up the most ink. Just my opinion.

A. When I first began burning CDs I employed a similarly conservative strategy, and I believe for good reason. However, both CD-R blank and recorder quality has been constantly improved, and I now burn CD-Rs at default speed with no problems. However, I do take pains to purchase only the best quality CD-R blank discs that are available. That strategy has for several years provided 100 percent reliability.
Regarding your Canon CanoScan FS 2710, I would suggest looking into obtaining a VueScan driver for the scanner. VueScan can at least provide the ability to run the scanner and scan to high-bit raw files, which you can then color correct and adjust in Photoshop. You can check it out and download the software from their website at: www.hamrick.com.
I would disagree with your assumption that Epson's strategy with ColorLife paper requiring 2880dpi resolution has anything to do with ink usage, as the difference in ink used between resolutions is negligible and has to do more with image quality and longevity, considering that one reason for promoting the paper is longer life based on tests by Wilhelm-Imaging Research. If at a higher resolution the printer used a significantly greater amount of ink, then the resulting print image would be much, much darker.
