Digital Innovations

Adobe's Photoshop Camera raw plug-in lets you directly manipulate the original data captured by a digital camera sensor. Adobe claims the Mac OS version will only work in OS X 10.2, but this screen shot was made under OS X 10.1.5 from an image captured with a Canon EOS D60 on a nice spring day in Colorado.

When making portraits, I typically shoot in Program mode (sometimes shifting aperture or shutter speeds) and almost always--indoors and out--use a Sto-Fen (www.stofen.com) diffuser on the flash to soften the direction and intensity of the light. The flash head itself is often tilted in some oddball direction to avoid that dreaded, flat "flash-on-camera look." All of this is true when working with the 420EX, but when I was teaching a workshop at FOTOfusion (www.fotofusion.org) I borrowed a student's 550EX (he also had a Sto-Fen diffuser) and it produced similar if not identical results.

The Raw Truth
Another recent e-mail was from a reader who just bought a new Canon EOS 10D and asked: "I'm only shooting raw and it's a pain to convert and download. Please help." Using an uncompressed raw image, sometimes nauseatingly called a "digital negative," does provide more precise control over an image's tonal range and detail, but I've always used the largest JPEG setting because I simply couldn't tell the difference. Large raw files take longer to capture, so you can't shoot fast action such as motorsports, and eat up more CompactFlash card space, and I never seem to have enough of them as it is.

(Below) The original image was made with a Hasselblad Xpan and Kodak Portra 400BW film. The film was digitized with an Epson Perfection 3200 Photo scanner and opened in Adobe Photoshop. A duplicate layer was created, a selection made around the mailbox, and Xenofex 2's Rip Open filter was applied to let the background layer show through. To create some interest and contrast the background layer was toned using Photoshop's built-in Sepia action.

Two new Photoshop compatible plug-ins have changed my mind--a little anyway--about using raw capture. The first is LaserSoft Imaging's (www.lasersoft.com) SilverFast DC 6 that supports raw formats from Nikon D1; Canon; Kodak DCS, DCR, ProBack; Fuji; Olympus; Minolta; and Sigma. It will be available for Mac OS 9/OS X and Microsoft Windows. You can read more about SilverFast DC 6 in my PMA report in the June 2003 Shutterbug. The other is Adobe's Camera raw plug-in that lets you open Canon, Fuji, Minolta, Nikon, and Olympus raw image files from within Photoshop instead of using the lame software that's included with the camera and sometimes available only at extra cost.

Adobe's Camera raw lets you preview raw files within Photoshop's File Browser in 16-bit mode and allows you to directly manipulate the original data captured by a camera's sensor. For each supported camera, default and custom raw image settings can be adjusted and saved between sessions. Bundled with Camera raw is a JPEG 2000 plug-in that supports this new format that uses wavelet technology for greater data compression while offering better image quality than JPEG. Wavelet algorithms process data at different scales or resolutions. Often less than 1 percent of the original data size is sufficient for "very good" representation. The Photoshop Camera raw package costs $99 and can be downloaded from www.adobe.com.

There were still two things that bothered me about Camera raw. The list of supported cameras, as posted on www.adobe.com/products/photoshop/cameraraw.html, does not include the EOS 10D that I just bought. Check the web page to see if it supports your favorite digital camera. But I got to wondering, since the 10D has the same chip as the D60, which is supported, how much difference could it be? In addition, both Adobe Systems and the Camera raw installer say the Mac OS version is only compatible with OS X 10.2, the so-called Jaguar. With OS X 10.1.5 installed, it shouldn't work until I upgrade but...just for the heck of it, I shot a raw file with my Canon EOS D60 and stuck the CompactFlash card in my card reader. The file appeared in File Browser, showed in the OS X Open dialog and I opened it using Camera raw. When I tried the same thing with an EOS 10D file, no dice. I checked with an Adobe spokesperson and asked when the plug-in would be updated for new cameras: "The plug-in will not be updated. The technology will be incorporated into the next version of Photoshop, at which time more cameras will be supported." So naturally I asked when that next version would appear. The short answer is "no comment," so I guess we 10D owners are out of luck...or not. This same spokesperson once told me that when, the as-yet unnamed, Camera raw plug-in was first shown at a trade show that is was just a "technology demonstration," not a product, so who knows.

Plug-In Of The Month
Alien Skin Software's (www.alienskin.com) Xenofex 2 is an update to this popular package of plug-ins that simulates natural phenomena such as clouds and lightning. Improved controls allow users to "aim" lightning bolts by specifying beginning and end points. In addition, photographers can age their photographs using the Stain, Cracks, and Burnt Edges filters.

Xenofex 2 also offers distortion effects that let you warp images using Television, Crumple, and other filters. The 3D effects, such as Flag, Shatter, and Rip Open, expand your creative palette. Xenofex 2 can transform images into jigsaw puzzles, constellations, and mosaics with a single click. The advanced edge detection of Constellation and Classic Mosaic properly matches colors and aligns tiles/stars for the best effect. All of the plug-ins have a simple, uncluttered interface that let you tweak their effects in a huge preview window. It also includes layers and command menus. Built-in presets provide hundreds of one-click effects. Download a demo from their web site and give it a try.

How Compatible Are Your Plug-Ins?
Not all Photoshop compatible plug-ins are, well, compatible with one another. The most common problem is identification number conflicts. Every plug-in has a unique identification number but--get this--nobody polices how these numbers are assigned, so it's possible that different companies' plug-ins can have the same ID number. When that happens, the first one to load (in alphabetical order) captures that slot and any plug-ins trying to use that number won't load. And that, dear friends, is what's happening with some Auto FX (www.autofx.com) and nik Multimedia (www.nikmultimedia.com) plug-ins. At PMA, I urged the creation of a Plug-In Council that would maintain an official registry of ID numbers, but nobody seemed interested. Both Auto FX and nik Multimedia are aware of compatibility problems and are trying to solve it. In the meantime, if you want to use all of the 50+ plug-ins that are part of nik Color Efex Pro!, you have to temporarily (or permanently) uninstall any Auto FX plug-ins that you have installed.
