TAILIEUCHUNG - Photoshop 6 for Windows Bible- P22

Photoshop 6 for Windows Bible- P22:If you are reading this foreword, it probably means that you’ve purchased a copy of Adobe Photoshop , and for that I and the rest of the Photoshop team at Adobe thank you. If you own a previous edition of the Photoshop Bible, you probably know what to expect. If not, then get ready for an interesting trip. | Chapter 12 Working with Layers 601 And finally here s a question for all you folks who think you may have Photoshop mastered. Which of the brush modes explained in Chapter 5 is the exact opposite of Lock Transparency The answer is Behind. To see what I mean turn off Lock Transparency. Then select the paintbrush tool and choose the Behind brush mode in the Options bar. Now paint. Photoshop applies the foreground color exclusively outside the transparency mask thus protecting the opaque pixels. So it follows when Lock Transparency is turned on the Behind brush mode is dimmed. The moral Behind is not a true brush mode and should not be grouped with the likes of Multiply and Screen in the Options bar. If you ask me the better solution would be a Lock Opacity check box in the Layers palette. Alas Adobe s engineers seem to have better things to do such as add three other Lock check boxes none of which have the slightest thing to do with locking opacity. But just because I ve been complaining about the Behind brush mode for the last oh gosh seven years doesn t mean that I m bitter or anything. Heavens no. I like to be ignored It robs my life of meaning which is precisely what I m looking for. In fact I think I ll go and end it all right now. And for what A check box. That s all I want. A small and unobtrusive check box possibly with a picture of my face next to it and a little caption reading Yes Deke you were right. Can you ever forgive us for being such knot-heads I mean really am I asking too much So in conclusion Lock Transparency is your friend Behind is the tool of Satan. Too bad so few things in the world are this black and white. Creating layer-specific masks In addition to the transparency mask that accompanies every layer except the background you can add a mask to a layer to make certain pixels in the layer transparent. Now you might ask Won t simply erasing portions of a layer make those portions transparent The answer of course is yes. And I hasten to add .
