Using Adobe Photoshop CS, Part 2 - Getting Rid of Dust and Scratches
(Page 7 of 12 )

Usually when scanning from photo prints, you'll notice dust or scratches in your scanned image. Sometimes it's because the glass on your scanner is dirty (I clean my scanner glass daily), whereas other times it's because the photo itself has scratches on it. In those cases you can choose Filter, Noise, Dust & Scratches to clear them up (see Figure 5.117). Be careful not to use too high a setting because doing so might blur out parts of your image that should remain sharp.


Tip -Rather than applying the Dust & Scratches filter to an entire image, I use the following technique to save time and take advantage of the Dust & Scratches filter while retaining the sharp parts of my image:

Apply the Dust & Scratches filter, and use a setting that is just a bit more than you would ordinarily use. Then click on the Create New Snapshot icon in the History palette to create a snapshot of the blurred image. Press (Command-Z) [Ctrl+Z] to undo the Dust & Scratches filter. You now have your original file. Select the History Brush, and in the History palette click the box to the left of the snapshot you just took. This sets the History brush to paint from that snapshot. Now paint over the scratched-up areas on the photo (use a big enough soft-edged brush). This allows you to easily and selectively apply the Dust & Scratches filter.

Applying Filters

One of Photoshop's trademarks is the capability to quickly change the appearance of a photograph or an image. Not only does Photoshop ship with a laundry list of filters for this purpose, but you also can buy other third-party filters for even more specialized purposes. Here we'll discuss some of the more widely used filters.


Tip -If you notice that most of Photoshop's filters are grayed out, there's a good chance your document is set to grayscale or CMYK (see Figure 5.118). In reality, many of Photoshop's filters will work only in RGB documents. This is specifically due to the fact that those filters use calculations that can be applied only in RGB. If you need to use one of these filters in a CMYK document, choose Image, Mode, RGB to switch color modes, apply the filter, and then choose Image, Mode, CMYK to go back to your original color space. Be aware that color shift may (and most likely will) occur.


Filter Gallery

Besides being able to retouch just about any image in Photoshop, you can also stylize or adjust a photo to give it a certain look. For example, Photoshop can apply a filter to a standard photograph to make it appear as if was painted with watercolor or drawn with chalk and charcoal.

Figure 5.118 Many filters are grayed out for CMYK images.

Photoshop's filter menu is filled with a plethora of these types of effects (see Figure 5.119), but unless you know exactly what you're looking for, it can be quite time-consuming having to go through them all and see how your selected image will look with a filter applied. So it's with good reason that Photoshop CS introduced a new feature called Filter Gallery that allows you to visually apply any of Photoshop's many artistic and stylistic filters-and even combine them-in a single dialog box.

Figure 5.119 Choosing from Photoshop's plethora of stylistic filters.


Note -The Filter Gallery feature works only on RGB and grayscale files. To apply a filter to a CMYK file, you'll have to first convert the file to RGB, apply the filter, and then convert the image back to CMYK.


Choose Filter, Filter Gallery and you're presented with a full-screen dialog that consists of four sections (see Figure 5.120). The far-left area gives you a preview of your image, and the middle section is where you choose the kind of filter you want to apply. The upper-right section allows you to tweak the individual settings of the filter that's chosen in the center panel, and the lower-right panel allows you to control multiple filters, and how they are applied to your image.

Figure 5.120 The Filter Gallery dialog.

Using Filter Gallery is not only easy and useful, but addictive and fun. The possibilities are endless. Why settle for a standard stock photo for that brochure when you can create an entire stylized look by applying filters?

What makes this feature so powerful is how it enables you to experiment and apply multiple filters to your image. On the lower-right section of the dialog, use the New Effect Layer button to add another effect (as many as you like), and choose a different filter from the middle panel (see Figure 5.121). Stacking order is important, so you can also drag the filters up and down to see how the appearance changes depending on which filter is applied last. You can also disable an effect by clicking on the eye icon to the immediate left of the effect listing.

Tip -You can also apply filter effects to gradients or patterns that you've created to make interesting and unique backgrounds.
