Although some of the color choices overlap, you'll get very different looks when choosing between filter effects and toning effects. Filter effects add no color to the monochrome image. Instead, they reproduce the look of black-and-white film that has been shot through a color filter. That is, yellow will make the sky darker and the clouds will stand out more, while orange makes the sky even darker and sunsets more full of detail. The red filter produces the darkest sky of all and darkens green objects, such as leaves. Human skin may appear lighter than normal. The green filter has the opposite effect on leaves, making them appear lighter in tone. Figure 3.28 shows the same scene shot with no filter, then yellow, green, and red filters.
The sepia, blue, purple, and green toning effects, on the other hand, all add a color cast to your monochrome image. Use these when you want an old-time look or a special effect, without bothering to recolor your shots in an image editor. Figure 3.29 shows the various toning effects available.
Adjusting Styles with the Picture Style Editor
The Picture Style Editor, shown in Figure 3.30, allows you to create your own custom Picture Styles, or edit existing styles, including the Standard, Landscape, Faithful, and other predefined settings already present in your EOS T2i. You can change sharpness, contrast, color saturation, and color tone—and a lot more—and then save the modifications as a PF2 file that can be uploaded to the camera, or used by Digital Photo Professional (described in Chapter 9) to modify a RAW image as it is imported.
To create and load your own Picture Style, just follow these steps.
1. Load the editor. Launch the Picture Style Editor (PSE, not to be confused with the other PSE, Photoshop Elements).
2. Access a RAW file. Load a RAW CR2 image you'd like to use as a reference into PSE. You can drag a file from a folder into the editor's main window, or use the Open command in the File menu.
3. Choose an existing style on which to base your new style. Select any of the base styles except for Standard. Your new style will begin with all the attributes of the base style you choose, so start with one that already is fairly close to the look you want to achieve ("tweaking" is easier than building a style from the ground up).
4. Split the screen. You can compare the appearance of your new style with the base style you are working from. Near the lower-left edge of the display pane are three buttons you can click to split the old/new styles vertically, horizontally, or return to a single image.
5. Dial in basic changes. Click the Advanced button in the Tool palette, shown at right in Figure 3.30 to pop up the Advanced Picture Style Settings dialog box that appears at left in the figure. These are the same parameters you can change in the camera. Click OK when you're finished.
6. Make advanced changes. The Tool palette has additional functions for adjusting hue, tonal range, and curves. Use of these tools is beyond the scope of a single chapter, let alone a notation in a bulleted list, but if you're familiar with the advanced tools in Photoshop, Photoshop Elements, Digital Photo Pro, or another image editor, you can experiment to your heart's content. Note that these modifications go way beyond what you can do with Picture Styles in the camera itself, so learning how to work with them is worth the effort.
7. Save your Picture Style. When you're finished, choose Save Picture Style File from the File menu to store your new style as a PF2 file on your hard disk. Add a caption and copyright information to your style in the boxes provided. If you click Disable Subsequent Editing, your style will be "locked" and protected from further changes, and the modifications you did make will be hidden from view (just in case you dream up your own personal, "secret" style). But you'll be unable to edit that style later on. If you think you might want to change your custom Picture Style, save a second copy without marking the Disable Subsequent Editing box.
Now it's time to upload your new style to your Canon EOS T2i using one of your three User Def slots in the Picture Style array. Just follow these steps.
1. Link your camera for upload. Connect your camera to your computer using the USB cable, turn the T2i on, launch the EOS Utility (if it doesn't pop up automatically), and click the Camera Settings/Remote Shooting choice in the splash screen.
2. Choose the Shooting menu. It's marked with an icon of a white camera on a red background, from the menu bar located about midway in the control panel that appears on your computer display.
3. Access the Picture Style. Click on the Picture Style choice to produce the screen shown at left in Figure 3.31. Highlight one of the three User Def choices and click Detail set. (Note that you could also click one of the predefined Picture Styles, such as Standard or Landscape, and change their parameters, too.) The Picture Style settings dialog box, at right in Figure 3.31, appears.
4. Specify your new style. In the Picture Style settings dialog box, click the Open button, and navigate to the new Picture Style that you named and saved in Step 7 above.
Upload your new style to your EOS T2i using the EOS Utility.
5. Upload to your camera. Click the Apply button and your Picture Style will be uploaded to the T2i into the User Def slot indicated at the top of the dialog box.
6. Exit EOS Utility. Click Close to quit the Picture Style settings dialog, and exit the EOS Utility. Disconnect your camera from your computer, and your new style is ready to use.
I've found that careful Googling can unearth other Picture Styles that helpful fellow EOS owners have made available, and even a few from the helpful Canon company itself. My own search turned up this link: http://web.canon.jp/imaging/picturestyle/ file/index.html, where Canon offers a half dozen or more useful PF2 files you can download and install on your own. Remember that Picture Style files are compatible between various Canon EOS camera models (that is, you can use a style created for the Canon 50D with your T2i), but you should be working with the latest software versions to work with the latest cameras and Picture Styles. If you installed your software from the CDs that came with your EOS T2i, you're safe. If you owned an earlier EOS and haven't re-installed the software since your camera upgrade, you might need to re-install the software.
Try the additional styles Canon offers for yourself. They include the following:
■ Studio Portrait. Compared to the Portrait style built into the camera, this one, Canon says, expresses translucent skin in smooth tones, but with less contrast. (Similar to films in the pre-digital age that were intended for studio portraiture.)
■ Snapshot Portrait. This is another "translucent skin" style, but with increased contrast with enhanced contrast indoors or out.
■ Nostalgia. This style adds an amber tone to your images, while reducing the saturation of blue and green tones.
■ Clear. This style adds contrast for what Canon says is additional "depth and clarity."
■ Twilight. Adds a purple tone to the sky just before and after sunset or sunrise.
■ Emerald. Emphasizes blues and greens.
■ Autumn Hues. Increases the richness of browns and red tones seen in Fall colors.
This menu choice, the first in the Shooting 3 menu screen, lets you "take a picture" of any dust or other particles that may be adhering to your sensor. The T2i will then append information about the location of this dust to your photos, so that the Digital Photo Professional software can use this reference information to identify dust in your images and remove it automatically. You should capture a Dust Delete Data photo from time to time as your final line of defense against sensor dust.
To use this feature, select Dust Delete Data to produce the screen shown in Figure 3.32. Select OK and press the Set button. The camera will first perform a self-cleaning operation by applying ultrasonic vibration to the low-pass filter that resides on top of the sensor. Then, a screen will appear asking you to press the shutter button. Point the T2i at a solid white card with the lens set on manual focus and rotate the focus ring to infinity. When you press the shutter release, the camera takes a photo of the card using aperture-priority and f/22 (which provides enough depth-of-field [actually, in this case depth-of-focus] to image the dust sharply). The "picture" is not saved to your memory card but, rather, is stored in a special memory area in the camera. Finally, a "Data obtained" screen appears. If the Rebel T2i was unable to capture the data, you'll be asked to repeat the process. Make sure the camera is pointed at a plain white surface that's evenly illuminated.
The Dust Delete Data information is retained in the camera until you update it by taking a new "picture." The T2i adds the information to each image file automatically.
