This is a problem with Photoshop 5.0 for Windows. It is not a problem with our book.
It was kindly pointed out and discovered by one of our readers, that QuarterDeck Cleansweep Deluxe prevents Photoshop 5.0 for Windows from loading "fastcore routines". What this means is that if you use Cleansweep, the Distort filters and several others will not load, and you won't be able to use them. It is the author's opinion that you should remove Cleansweep; your other options are to use Photoshop 4, or live without some of the native Photoshop 5.0 filters. This has been reported to Adobe Systems as a bug 6/29/98.

In the tutorial "Using the Measure Tool ", we forgot to tell you in step one to set the Info palette to pixels. If you don't do this before using the Measure tool, you'll be stumped with the assignment. Here's how this section should read:Here's how to get the ball rolling and perform some preliminary calculations:
Using the Measure Tool
- Press F8 if the Info palette is not already on screen, click on the XY field crosshair (toward the bottom left of the Info palette), and choose Pixels from the flyout list. Now, everything you measure with the Measure tool is expressed in pixels on the Info palette.
- Open the Flamingo.tif image from the Chap17 folder on the Companion CD. Double-click on the Zoom tool to make the viewing resolution of the image 100% (1:1). 3. Size the image window so that you see only the face of the officer. You'll need to leave room onscreen to display the stand-in's image.

The reference to the Dock2.psd image should have been to the Dock2.tif image in the chapter 2 folder, so the exercise goes like this:
Figure 2.2 Reflective scanning emphasizes the extremes in tonal distribution within a photograph, whereas transparency scanned Photo CD images retain clarity in the tonal extremes as well as a good tonal balance in the midtones.
If you'd like to witness the qualitative difference between a reflective scan and a transparency scan, open (in Photoshop) both the Dock1.tif and Dock2.tif images from the Chap02 folder on the Companion CD. Dock1 is from a flatbed scanner, and Dock2 is from a Photo CD
Now, let's say that your client does not have the negative to Dock1.tif. You are forced to work with this image in Photoshop. Don't despair; with a few cosmetic touchups you can bring some life to the image, as you'll learn in the following steps: Adjusting Tone, Balance, and Focus from a Scanned Image- Open the Dock1.tif image from the Chap02 folder on the Companion CD. You might also want to open Dock2.tif as a reference for your work.
- With Dock1.tif in the foreground, press Ctrl(Cmd)+L to display the Levels command.

We accidentally left out the Flower.tif image from the CHAP01 folder. This is not a mistake that will make you fail at Photoshop, clog your kitchen sink, or cause war between your country and a neighboring nation or anything. But we though it's only right and proper to correct this oversight ASAP. Right-click on Flower.jpg (Mac: Hold Ctrl+click) below, and then choose to download the file to your system. Open the file in Photoshop and you can see the color channel principle we're trying to demonstrate on page 22 or so (depending on which language version of the book you own).

Inside Adobe Photoshop 5, Chapter 1...
There is a minor error in figure 1.1. This figure shows the visual difference between a bitmap image and a vector image. Unfortunately, the formula listed in the image to produce the vector curve is wrong. It should look like this, and the formula within the image is correct here:
