Aside from the intricacies of exposure and light metering, photo enthusiasts generally find depth of field the most difficult concept to master. That's understandable particularly since this is a hypothetical factor based on subjective judgment.

Although many of Sigma's new lenses incorporate the latest technology and/or premium grade optics, this manufacturer continues to compete aggressively in the market for affordable zoom lenses. In addition to its APO, Aspherical, and HSM series, Sigma...

Is there a serious photo enthusiast out there who doesn't harbor a desire to see his or her work published? Well, the vast majority I know would love to market their images to books, magazines, and advertising agencies. In fact, the most commonly...

Several new dye sub printers have been recently announced. These printers employ
thermal transfer technology--they apply heat to a special ink ribbon to produce
colored gas that forms an image on special media. All provide approximately
300dpi resolution, plenty for continuous tone output.



High Speed Pro Printers

Kodak recently introduced two new roll-fed thermal transfer 300dpi Professional
models (with automatic cutters) that generate high quality output for use as
proofs or for immediate sale. Both employ Ektatherm media said to produce prints
that will "last a lifetime". An archival rating has not yet been
published. (They require a computer running Windows 2000 or XP; Mac support
is not available at this time.) The Professional 6850 Digital Photo Printer
is lightning fast. It can deliver 6x8-inch glossies in 15 seconds or 4x6's
in a mere 4 seconds -- hundreds of such photos in a series (without operator
intervention) when high volume is required. (List price $2900; cost per print
not stated; available in August 2005.)

certain lighting conditions, images can exhibit a strong
overall "color cast" or tint, as in this

pollution level. (Auto white balance.)

Until recently, Lexmark printers were primarily multi-purpose or industrial
machines but their latest models are dedicated to photo printing. Based on a
three year R&D effort, the P915 Home Photo Printer and P6250 Photo Center
boast some impressive features. These include high resolution, a full slate
of direct printing amenities, software for automatic print enhancement plus
new archival inks for print permanence. The two printers are identical in most
respects but the P6250 Photo Center is larger because it includes a significant
extra, a built-in flatbed scanner.

As recently as 18 months ago, a built-in image stabilizer was a rarity in digital
cameras. It was available only in a couple of Panasonic models and one Konica
Minolta DiMAGE camera. Today, an increasing number of digicams -- from four
manufacturers -- employ some form of camera shake compensating device. And there's
even a digital SLR with a built-in Anti-Shake mechanism, the Maxxum 7D. We expect
this trend to continue with other manufacturers jumping on the bandwagon. "Sounds
great if you're into high-tech gizmos," you may be thinking, "but
is this feature really necessary?"

As the price of D SLR's, high-end digicams and film scanners has declined
substantially, an increasing number of photo enthusiasts are able to make high
resolution images. At some point, most will recognize that their current printers
are due for replacement. Frankly, many existing machines cannot provide the
optimal quality -- or the large output sizes -- that high resolution image files
can support. Consequently, we're seeing a trend to superior photo printers
in letter size and especially in larger formats.



With more photographers doing more of their own printing the issue of print
permanence was certainly a hot topic, encouraged especially by Hewlett-Packard
who, at the recent PMA show, featured Henry Wilhelm as a speaker. President
of Wilhelm Imaging Resource, an independent stability testing lab, Wilhelm is
certainly an expert in all issues relating to archival issues. He recently made
news with the announcement of a new standard for print life, the WIR Display
Permanence Rating. Many existing photo printers and papers should qualify for
this Certification program, which requires a minimum on-display life of 25 years.
Do note, however, that some manufacturers may prefer to wait for standards to
be published by the international ISO or the American ANSI organization. This
could be a long wait, according to some insiders.



New Printers We've Seen

Employing the UltraChrome Hi Gloss pigmented inkset originally designed for
the (letter size) R800, the new Epson Stylus Photo R1800 uses the Gloss Optimizer
coating to produce beautiful 13x19" (or longer) prints on glossy papers.
Another fast machine, this one can also make an 11"x14" color image
in less than two minutes thanks to Advanced Micro Piezo ink jet technology with
180 nozzles per ink. The Stylus Photo R1800 offers resolution up to 5760 x 1440
optimized dpi and it can print on sheet and roll paper or onto inkjet printable
CDs and DVDs. (Street price $549.)

Adobe has released an updated beta version (v3.3, 11/10/05) of their Adobe
Camera Raw plug-in for raw file conversion with a few enhancements. (Compatible
only with Photoshop CS 2 as well as Elements 3.0 and 4.0.) Support for additional
cameras has also been added, including the Canon EOS 5D, EOS 1D Mark II N, Pentax
*ist DL and *ist DS2. A minor fix has also been made to the Adobe DNG converter,
"improved decoding for some camera models". Do note that this is a
beta version, although it appeared to work perfectly in my preliminary tests.
When installing the Camera Raw plug-in, be sure to follow the instructions exactly
as described on the Adobe web site. The download for Mac and Windows is available
at http://www.adobe.com/support/downloads/new.jsp.
