Error 1 Page 24:
Under the section titled "Changing How Far Back You Can Go", step 1 states to click "Photoshop --> Preferences". There is no menu item named "Photoshop" to click on. It's actually "Edit --> Preferences".

Error 2 Page 20 & 23: This is not an error, just language use.
Page 20: under description of the Tools Panel, the 1st sentence reads "The most important panel in Photoshop is the one named Tools"

Then on page 24, under Layers, "The Layers panel is the single most important panel in Photoshop".

So which one is most important? Just kidding. Thought I'd bring that up. I'm a beginner user of PS and so far found your book to be awesome. Thanks for making it happen. Other books are too confusing for a novice like myself.

Note from the Author or Editor:
Page 23, under "Layers" subhead, change 1st sentence from "The Layers panel is the single most important panel in Photoshop." to read "The Layers panel is home to the single most important concept in Photoshop."

Page 24, under "Changing How Far Back..." subhead, under numeral 1, change 2nd to last sentence from "On a PC, choosing Photoshop > Preferences..." this should read: "On a PC, choosing Edit > Preferences..."

Cahpter 16fs, instead of Chapter 16fs

Note from the Author or Editor:
Last bullet, reword last part of next to last sentence & last sentence, beginning with parens. Change it to read: "(you'll learn more about that in Chapter 5). Chapter 16 has the scoop on if and when you should switch to CMYK mode.

2nd line " Add a layer below.........."

Would suggest to add the word "blank" ;i.e Add a "blank" layer below.....

Note from the Author or Editor:
Change "Add a layer below it..." to read "Add a new layer below it..."

References other ways to use the rounded rectangle tool to create a mask.

Note from the Author or Editor:
