(Well, if you’re going to refer to me as the “Incomperable Colleen” I’m certainly going to try….)
If you’ve made it to Lesson 7 in Photoshop CS4 Channels & Masks One-on-One and are finding that the practice file Ancient doorway.psd is behaving badly, it’s because the file is truncated, i.e., corrupt. (No idea how it happened, just that it did happen.)
But no fear. I’ve attached the full file in all its splendor. Just right-click on this link here or the image below and choose Save or Download. Unzip the 18.8MB download and it’ll grow into a 26.2MB PSD doc. Copy it over the bad file included with the book and you’ll be good to go.
I’ll get it up on the O’Reilly errata page on Monday. Thanks for the heads up. Someone (kindly?) identified it there as a “minor technical problem” instead of “My %&#@ing file won’t open!” I dont’ think it’s been there long, because Deke is supposed to get emails everytime those items go up and he would not have abandoned you on his male-bonding snow-mobiling adventure if he’d known.
I’m also downloading the disk image to see if I can spot where things went wrong (you know, so I know where to subtly but scathingly place blame), but I’d also encourage you to report the difficulty to O’Reilly Customer Service (email@example.com). That way they can track the occurances of the problem and figure out how best to resolve it in future editions. And because some people will report their frustrations there first, and while they may not be as cool as you dwellers of dekeWorld, they still deserve a working file.
