Section 26. Repairing Image Flaws

#26. Repairing Image Flaws

Photoshop is considered the quintessential tool for retouching and repairing images. It can remove blemishes, crow's feet, and red eye, and re-create missing corners of old photographs as if by magic. And because those magicians at Adobe are continually improving upon the set of retouching tools and filters in Photoshop, it serves you well to know what's new and improved in CS2 for repairing images.

Repairing in Perspective

Before Photoshop CS2 arrived on the scene, it was rather difficult to repair images with obvious perspective planes, such as the side of a building. CS2 introduces the amazing Vanishing Point filter to effortlessly retouch and paint on images in perspective. To access this filter, choose Filter > Vanishing Point. Next, establish your perspective planes. You can then clone stamp (with healing), paint, and paste content while Photoshop places every adjustment in the correct perspective. Amazing is definitely an understatement.

The Healing tools in Photoshop CS2 make it incredibly easy to repair defects in an image. The Healing Brush tool is like the Clone Stamp tool with smarts. You paint from another sampled part of an image, but the Healing Brush blends the painted pixels seamlessly by matching the texture, lighting, shading, and transparency of the pixels being sampled to the pixels being healed. The new Spot Healing Brush makes the retouching process even easier (if that's possible) by automatically sampling the surrounding area being healed. This essentially gives you a one-click retouch tool (Figure 26a). Another repair tool that's been made one-click smart is the Red Eye tool . Just click anywhere in the red of the eye with the tool to fix the problem; Photoshop does the rest. It even works on green and white eyes that plague photographs of dogs and cats.

Figure 26a. Using the Spot Healing Brush, I was able to remove the painter in one click.

In addition to the assortment of retouch tools Photoshop ships with, it also includes a handful of powerful filters to address overall problems that occur in photographs. For instance, the Lens Correction filter (Filter > Distort > Lens Correction) helps fix common lens flaws (Figure 26b), whereas the Reduce Noise filter (Filter > Noise > Reduce Noise) is specifically designed to help remove image noise and JPEG artifacts (Figure 26c). If your usual filters for dealing with noise are Despeckle or Dust & Scratches, it's time to give Reduce Noise a try.

Figure 26b. The new Lens Correction filter makes it easy to correct common lens distortion issues such as barrel and pincushion distortion, chromatic aberration, and lens vignetting.

Figure 26c. Digital imaging has brought forth such problems as JPEG artifacts, scanned film grain, and overall noise. The Reduce Noise filter eliminates these types of issues as fast as it was to make them.
