Subtitles of the Movie (Adobe Photoshop 7 / Layers / Layer Locks)
Let's say you've made some wonderful edits to your layer, and you may not want those edits to be accidentally overwritten or edited further. One option we have is to do something called the locking. And notice at the top of my layers palette in this section we have 4 lock icons. I'm going to show you how these lock icons work, and I'm going to select my flower layer here. And the first lock icon will lock the transparency. And what this means of course is that, remember there is a transparent area on our layer, and there is an area where there is pixel data. I'll just go ahead and turn the eyeball off on these other layers, so that we can easily see our flower layer. And with my transparency lock not enabled, I can of course choose something like this brush. I'll just go ahead and make that a normal brush. And of course edit my entire layer so I actually edited, painted on areas where it was transparent and I even painted on parts of my flower. And you know that's the case because of course I can move all that pixel data, so I'll go ahead and undo that and undo that again to get me back to my flower. What I can do here is lock the transparency area, so only areas that there are pixel data can be edited. So now if I choose my brush tool again, I can't paint where there is transparency, but where there is pixel data I can paint. Well undo that and make it a little bit more obvious by choosing a very graphically different color. So you can see that I'm actually editing or painting on the areas where there are pixels because I had the transparency locked. I'll go ahead and undo that. Another type of lock is locking the transparency, as well as the ability to edit any of our pixels on this layer with any kind of painting tool. That's this clicking on the brush lock icon, and now notice with that brush lock icon enabled that I get the international no or don't symbol. When I choose something like my brush tool, and if I go ahead and try to do that, Photoshop warns me that this layer is locked. I'll go ahead and unlock both of those features. Talk about another locking feature, and that is the ability to lock a layer's position. If you click this lock icon, we cannot move its position. So if I choose my layer mover tool, Photoshop warns me that I can't complete this request, because my layer is locked for this particular parameter. However I can of course paint on this layer. I just can't move it. Notice that whenever I choose to lock one of these parameters, Photoshop puts this little lock icon next to the layer name. I can lock all 3 of these parameters, essentially making my layer un-editable, by clicking on this last lock icon. Click on the last lock icon, and my light lock icon turns into a very dark lock icon, indicating that my layer is fully locked. And of course if you want to unlock any of these layers, all you need to do is make sure that you're on the targeted layer that has lock, and simply begin to turn off the locks by clicking the buttons until they don't look pressed in.
