Some Exotic Blending Modes
Photoshop's blending modes combine layers or channels in sophisticated ways, as you learned This documentiscreated withtrial version of CHM2PDFPilot2.16.100 uce a weathered, old-timey look to the photograph, taking advantage of the way Exclusion combines pixels. Exclusion mode is closely related to Difference mode. The latter examines the brightness information of each channel, and subtracts one from the other, depending on whichever is brighter. That sounds confusing, but it's not difficult to...
Orthochromatic Film
It hasn't been so long ago that black-and-white films incorporated the term pan in their nomenclature. Tri-X Pan, Verichrome Pan, Plus-X Pan, or even Panchromatic-X were the names of films I used early in my career. The term pan stood for panchromatic all colors and was important because it meant that these black-and-white films were roughly sensitive to red, blue, and green light in equal amounts. As odd as it might seem, that wasn't always the case. In the 40s and 50s, black-and-white films...
Aligned/Unaligned
When the Aligned box is marked, Photoshop copies pixels from the point that you first marked as the source by pressing Alt Option when you clicked to the point in the image where you begin cloning. Then, as you move away from that point, Photoshop uses the distance and direction the cursor moves from the cloning point to determine which pixels to copy. For example, if you move 1 4 inch up and to the left of the first point where you start painting, the Clone tool will copy pixels that are 1 4...
Why Two Grain Filters?
is document is created with trial version of CHM2PDF Pilot 2.16.100. Why does Photoshop include two filters called Film Grain and Grain, rather than one In practice, each operates a little differently than the other, producing different effects, but we can thank the free enterprise system for their existence. Photoshop's current Film Grain filter was originally part of a third-party set of 16 compatible plug-ins called Aldus Gallery Effects, which sold for 199. These filters proved so...
Reticulation
Reticulation is another one of those darkroom processes that can either ruin your film or generate some I meant to do that-style images. It results from rapid temperature changes during development. As you probably know, conventional photographic film consists of a silver-rich and relatively soft gelatin emulsion coated on a thin, but tough substrate such as polyester. When developing, black-and-white film is moved from a warm developer to a significantly cooler solution, the soft gelatin warps...

Preface
If you're serious about photography, you should be serious about Photoshop CS2 and its exciting new features, too. Whether you're a casual snapshooter, a dedicated photo buff, or a professional photographer, you have a major advantage over those who approach Adobe's flagship image editor from other backgrounds. You have everyday working experience with the kinds of imaging or darkroom techniques that Photoshop was designed to mimic, enhance, and surpass. You'll find that approaching Photoshop...
Photoshop CS's Filter Gallery
The last version of Photoshop CS introduced the Filter Gallery, which has been optimized in CS2. Not all filters in the Photoshop repertoire are included in the Gallery. The roughly four dozen filters that are included have a new look that's compatible with the Filter Gallery interface. You'll find them in the Artistic, Brush Strokes, Distort, Sketch, Stylize, and Texture categories. Not all the filters in those general categories are included in the Filter Gallery. For example, the Stylize...
High-Contrast Images
Many years ago, some well-meaning soul discovered that super-high-contrast images had an interesting, minimalist look that stripped images down to their bare bones. Andy Warhol, although not best known as a photographer, used this effect in his work, including his famous Marilyn Monroe series. Indeed, high contrast images are easy to achieve simply by using lithographic films intended for reproducing line art. Litho films have a built in threshold that must be exceeded before an image is...
Figure 3.39. An unprocessed infrared photo looks like this.
Load the photo into Photoshop you'll find IR Landscape on the website and follow these steps 1. Choose Image gt Adjustments gt Autolevels. The image will now look like the one in Figure 3.40, which is interesting in its own right. Figure 3.40. Autolevels adjustment transforms the photo into this version. Figure 3.40. Autolevels adjustment transforms the photo into this version. 2. Next, choose Image gt Adjustments gt Channel Mixer. With the Red output channel selected, you'll see that the Red...
Photoshop CS Photo Filters
Photoshop CS has a Photo Filters effect hidden in the Image gt Adjustments menu. It's primarily of use to photographers who want to apply familiar filter effects to their image, rather than use the program's color correction facilities. Or, it can be used to quickly add filter-like color for special effects. For example, films are produced even today balanced for a particular kind of light source. The most common films are designed to produce accurate colors when exposed under daylight...
Figure 8.20. Use two gradients to create a split-filter effect in Photoshop.
4. Select your two colors as the foreground and background colors, using your favorite method the Eyedropper tool in the Swatches Palette works for me . 5. Drag from the top to the bottom of one of the transparent layers, holding down the Shift key to make sure you drag in a straight line. This applies the foreground color as a gradient in that layer. 6. Press X to swap the foreground and background colors. 7. Drag from the bottom to the top in the other transparent layer to create the lower...
Perspective Control
Most of the pictures we take, whether consciously or unconsciously, are taken head-on. In that mode, the back of the camera is parallel to the plane of our subject, so all elements of the subject, top to bottom, and side to side, are roughly the same distance from the film or digital sensor. Your problems begin when you tilt the camera up or down to photograph, say, a tree, tall building, or monument. The most obvious solution, stepping backwards far enough to take the picture with a longer...
