How to Touch Up Photos in Mac's iPhoto '11
To perform simple touch-ups on a photo, use iPhoto 11's editing tools. Mac's iPhoto can remove red-eye and blemishes; crop, rotate, straighten, brighten, and improve contrast; and apply a variety of special effects to improve your images.
Select an image and switch to full-screen edit mode.
To view your image fully so you can make changes, enter full-screen edit mode by clicking the Full Screen button.
Click the Edit button.
A panel appears along the right side with options to rotate, enhance, fix red-eye, straighten, crop, and retouch the picture.
You can compare before and after versions of pictures that you choose to edit. From Edit view, press the Shift key on the keyboard to see how the picture looked before you applied changes. Release Shift, and the edited image reappears.
Click Crop to crop the image or Rotate to rotate it.
Cropping means snipping away the periphery of an image to remove the parts you don't want to see. After you click Crop, choose the cropping area by dragging, then click Done. To limit the crop area to a specific dimension, select the Constrain check box and make a selection, such as 4x6.
When you click Rotate, the image rotates counterclockwise by 90 degrees. Keep clicking until the picture is oriented properly. Press the Option key while clicking to make the picture flip the other way. Click the Revert to Original button to undo your cropping if needed.
Click Enhance to automatically adjust brightness and contrast.
iPhoto automatically brightens a faded or too-dark image or adjusts one that's too bright by correcting the image's color saturation and tint.
Click Fix Red-Eye to remove red-eye or Retouch to repair blemishes.
After clicking Fix Red-Eye, select an Auto-Fix Red-Eye option (under Quick Fixes) to see if that does the trick. Otherwise, click a reddened pupil and drag the red-eye slider to match the red area's size. Click Done to complete the exorcism.
If you click Retouch, drag the slider to select a brush size. Then hold down the mouse button as you brush over a freckle, blotch, or pimple. iPhoto paints over these spots using surrounding colors. Use short strokes to avoid smearing an image. Alternatively, click over a small spot you want to remove. Click Retouch again when you're finished.
Click Straighten to straighten the image.
Drag the slider to rotate the picture 45 degrees or less in either direction. Some cropping takes place to maintain a rectangular image.
Click the Adjust tab to adjust the image manually.
Manually drag the sliders to adjust the exposure, contrast, highlights and shadows, color saturation, and other elements. If you get totally lost after messing with these settings, click Revert to Original to start from scratch.
Click the Effects tab to apply special effects
Click B&W (for black and white), Sepia, Antique (an aging effect), Fade (which lessens the color intensity in a photo), or Boost (for the opposite effect) to apply that effect to the image. Clicking Matte, Vignette, or Edge Blur alter the edges of the picture. You can combine effects if you want. Clicking None brings the photo back to its original state.
While the aforementioned buttons give you those one-click effects, you can repeatedly click these buttons to achieve the results you're looking for: Lighten, Darken, Contrast, Warmer, Cooler, and Saturate.
Click Revert to Original or Undo to reverse these effects.
Exit full-screen mode.
When you're through editing your image, exit full-screen mode by pressing the Escape key on the keyboard or clicking the Full Screen button again.
