The History Palette – Undoing Things

one of the most important things in Photoshop is knowing how to undo your mistakes. Luckily Photoshop has the history palette that is made specifically for that. And also you can say, you know what, save this spot. So if you're working on something, you think you're in a pretty good place. But you want to tweak it a little bit. You can always say, hey stop right here, do all your tweets and if you don't like it, you can go back in time. It's the history palette. So let's go in here and look at exactly how this works. So the history palette is next to our navigator here and it's this little thing right here that if you click it, you can see all the different things that have done. So this is that same caradon means that we just did and you can see all the different steps that I have taken and so you can see that if I go back one by clicking it. So you can see that the beans are on top of Karen. If I click this, you can see that oh that's before I placed the beans on the subject or right...

here I before I cleared out the selection. Here's the magic wand tool. Here's me just opening. So you can see every single thing I do shows up in history and you can go forward and back in time to either reconstruct or deconstruct what you've done. You can even do some really cool things. You can create something called a snapshot snapshot is to save, its like a bookmark to save your spot to say, you know what I think this is good. But I'm gonna just make sure by saving my place. So down here you'll see that you can do two things. One, you can create a new document from the current state. In other words. Say you know what, I think this is good but just make it a totally different documents so I can continue working on this one. But I've got a separate one saved just in case you can do that or you can go in here and there's this little camera, they click on that then it says snapshot one. So now watch what happens if I go in here, I'm just gonna start doing some wacky things. So I'm gonna get a brush and I'm gonna brush over her and then I'm going to maybe make her a little bit smaller. I'm gonna rotate her around, stick her up there like that. I'm going to, I don't know, we'll just do all kinds of things here. I'm gonna clone maybe her face and then put her face down there. I'm just doing some wacky stuff. Okay. The thing to understand is here inside of the history palette. I can either go back one at a time and say oops undo that undo that undo that or I can just go back to that snapshot so you just go back to that place that I saved. It's really, really nice now if you've really messed things up and you want to go all the way back to the very, very first, the very first time you open the document, you can just go to the very top Karen psD and there you have it. It is back to where you started. It's really cool. I can go back to that snapshot again. You can move around in time. Now. One of the things that is important to note, as soon as you close the image, the history is gone, it disappears. It doesn't stay there. So your history going back and forth in time, it's only good. As long as the document is open. As soon as you close the document, all that history goes away. So you want to make sure that if you need to undo stuff in the future that you don't close the document until you're in a good spot to do that. The other thing that we aren't going to cover in this workshop, but I'll just give you a little preview of what it is. There's a thing called the history brush. And so we go over here, you can see that we've got this guy right here, the history brush tool and what that allows you to do is to paint, you're undoing mistakes, you can paint the undoes, let me show you what I mean. So if we go back in time here to open, you can see there's Karen and there's a white background. Okay, so I'm gonna click to the left of that, there's a little paintbrush there, then I'm gonna go all the way down here and I'm gonna put this back to where we were in our snapshot. If I have this history brush tool and I go here to Karen, what I can do is as I paint, it's going to paint that all the way back to that specific place, the place where I opened but only where I paint. It's gonna undo where I paint to where I said to undo too. And so that's how that works. And so even if I go in here, let's go back to this first snapshot, I'm gonna go up here to Karen, I'm gonna get a normal brush. I'm gonna paint some crazy stuff on her, Maybe paint some red on her. I'm going to make her a little bit different position. So I've got that. So I've done some wacky stuff. And what I want to do is I want my history brush to go all the way back here to this opening. So I've got time on the Karen level here, I've got my history brush tool and when I paint it paints the history back on but only to where I undid that. So we have this amazing ability to undo each of our steps save our spot. And even paint our undoes. It's an amazing tool built into Photoshop

Mark did a great job at explaining things and going over them multiple times throughout the lessons. My only issue was that sometimes it went a little faster than I could keep up and I needed to rewind it a bit and start again. But from someone who has never worked in photoshop before I 100% recommend this class to anyone trying to learn.
