Chapter 5. Compositing in Photoshop CS

Compositing was thrust into the public attention in a big way early in 2005, when a certain home economics tycoon was released from prison and Newsweek published a jubilant photo of her on the coverexcept that it was actually only Martha's head superimposed on a model's body. Photoshop had done it again Whether the photo is an Oprah Winfrey Ann-Margaret hybrid (TV Guide, August, 1989) or nudging two pyramids closer together (National Geographic, February, 1982), when compositing is deemed to...

Chapter 3. Darkroom Techniques with Photoshop CS2

One of the things I miss the most, and the least, about photography from the predigital age is the fun and drudgery of laboring in the murk of a musty darkroom, surrounded by humid, acid-tinged odors and an eye-straining pale yellow glow. Despite an environment that would drive a claustrophobe nuts, miracles are created in the darkroom, and magical images often emerge from behind the heavy black curtain. Fortunately, there's no need to throw the spectacular images out with the stopbath water....

Photoshop's RAW Support

Photoshop CS now includes a Camera RAW plug-in (which was formerly an extra-cost option with Photoshop 7) that works quite well. It can be used only with the particular digital cameras that Adobe supports, typically from Nikon, Canon, or Konica Minolta and quite a few other vendors. In addition, Camera RAW supports the new Adobe Digital Negative (DNG) format. DNG is Adobe's attempt to create a common RAW format that can be used by all the different camera types. The list of supported cameras at...

Fisheye Lens

Fisheye lenses were originally developed as a way to provide a hemispherical view in unreasonably tight places, generally for technical reasons, such as examining the insides of a boiler, or for photographing things like the sky's canopy for astronomical research. Because of their specialized nature, they tended to cost a fortune to buy, but that didn't stop photographers of the 1960s who were looking for a way to come up with novel images. My own first fisheye lens was a second-generation...

Filters

Let's not get started on filters, just yet. In traditional photography, filters are handy gadgets you place in front of the camera's lens to produce a variety of effects. These can range from multiple images to split-field colorization (that is, blue on top and reddish on the bottom of an image, or vice versa) to glamour-oriented blur filters. Using third-party add-ons like those from Andromeda or Alien Skin, Photoshop can reproduce virtually any optical effect you can get with glass or gelatin...

Grainy Images

Film grain is an inescapable fact of life in conventional photography, as clumps of silver grain are roughly the This document iscreatedwith trialversionofCHM2PDFPilot 2.16.100.r the grains of silver in a film, the more sensitive that film is to light, and the better able it is to capture images in reduced lighting or with faster shutter speeds and or smaller lens openings. In the never-ending quest to increase the exposure speed of films, grain has been a frequent byproduct. Given the if you...

Using Live Histograms

As you learned from working with the Levels command, histograms are a useful tool for displaying information about the number of tones present in an image at each brightness level. A histogram consists of a series of up to 256 different vertical lines in a graph, arranged horizontally with the black tones represented on the left side of the graph, the white tones at the right side, and the middle tones located (you guessed it) in the middle of Thisdocumentis createdwithtrial version of...

Chapter 8. Using Photoshop CS's Filters

For a long time, Photoshop's use of filters remained quite stagnant, with few new filters added from release to release. Indeed, many of the best filters in the Photoshop arsenal dated back to Adobe's acquisition of Aldus Corporation, and its three Gallery Effects packages almost a decade ago. These 36 filters were eventually folded into Photoshop itself, and there were only a few minor additions to Photoshop's default array for many years. Now, Adobe has started to move forward again with...

Chapter 2. Camera and Lens Effects in Photoshop

With the new popularity of digital single lens reflex (SLR) cameras, the focus on lenses and their effects has increased. Everyone wants to get the compressed look found in long telephoto shots, or simulate the excitement possible by zooming a lens during exposure. But not every digital photographer is equipped with a camera that has a super-long zoom range, nor can those who've sprung for the price of a dSLR always afford to buy every lens they want to own. Lenses are very cool, but you may...

Chapter 1. Photoshop and Photography from 50,000 Feet

There's no rest for the leader of the pack. Although Photoshop has been the undisputed top dog among image editors for as long as most of us have been working with digital photography, Adobe's flagship pixel pusher has not been resting on its laurels. From the moment I finished work on the first edition of this book, which dealt with Photoshop 7.0, Adobe has been enhancing the program non-stop, adding features of special interest to photographers, such as enhanced manipulation of digital camera...

Dodging/Burning

Color and black-and-white prints are traditionally made using an enlarger, which casts an image of the film onto a photosensitive sheet of paper for a carefully calculated number of seconds. For about as long as photographers have been making prints, they have also been sticking their fingers, hands, or other objects in the light path to reduce the relative exposure of one part of an image (dodging) while increasing it in another (burning). The result is an image in which the light and dark...

Fixing Dual Catchlights

Here are those dual catchlights again, as shown in Figure 4.13. The brightest catchlight was caused by the electronic flash used to take the picture. The secondary catchlight can be blamed on a bright window behind the photographer. It's sometimes difficult to previsualize a picture well enough to realize that double catchlights are going to result (the main catchlight doesn't appear until the flash goes off, for example), so the easiest solution is simply to remove one of the reflections in...

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...

Creating a Saturation Gradient

Saturation Gradient

Still skeptical and want to try this for yourself Just follow these steps 1. Fill a rectangular image or selection with a color of your choice. 2. Choose Layer gt New Adjustment Layer gt Hue Saturation to create a spanking new adjustment layer that will let you modify the saturation of your color with great precision. 3. Click on OK in the New Layer box that pops up, and then click on OK in the Hue Saturation dialog box that appears. We're not going to use the sliders to adjust the saturation...

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...

Filter Special Effects Photoshop

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...
