History Brush Tool
below that we have the history brush tool. If you ever mess up on an image and you don't end up using layers for something like, for instance, if we have this image and I ended up coming into the image in making some sort of a change, maybe in this case I end up applying a filter. I click OK, and I wish I would have done that on its own layer because I want the background to look like that. That's noticed the oil paint filter, but I wish it wouldn't apply to his face his arms in similar areas. Well, I can go to the history brush tool, which is what I'm in right now. If I paint, it should paint with what the image originally looked like when you first opened it, and therefore I could bring these areas back. So if I don't want the filter or any other change that I've made to the image to apply to these areas, I can easily bring them back. You can also lower the A pass ity of this tool and therefore not bring it all the way back to the original, but blend the original version with this ve...
rsion just gonna get his other arm here. You should be aware, though, that on occasion the history brush will not work. And that is, if the original version of your picture is a different size than this one, that means you scaled it or you've cropped it in a way where the width and height of the image is different than the original, because then it doesn't know where to align the original image with this newly sized image. Also, if you've changed the mode of your picture, maybe if that picture started out in grayscale mode, he converted it RGB mode. It won't be able to use the history brush then, either. And the history brought, she should be aware, is related to the history panel. So let's go to the window menu and choose history. This is the history panel. It's simply lists everything you've done since you've opened your image. There is a limit on the number of steps that will remember in that limit can be found in your preferences if you choose. Performance in here is a choice called history states. It should be called undoes because that determines how maney induce you get, then That means if you do more than 50 things to this image, it will start forgetting the very first step. It's not that it won't apply it to your picture. It's just that you won't be ableto undo all the way back to the original. So if this is a list of everything I've done to this image, then what I canoe is if you look in the left column, there's an icon right here that looks just like the tool that I'm currently using. That's the history brush icon. Well, I can click on any one of these previous steps in that little left column to tell it exactly what I should paint with. So maybe I put it right there to say, I want to paint with what it looked like right after applying the the oil paint filter. Well, therefore, I could come in here and I could apply that Look back to the image. It just happens to be that that defaults to the very top portion, and that is always what your image originally looked like when you first opened it. But what that means is you can experiment and get back to what your image looked like in any past state by just going into the history panel in clicking in that left most column to tell it what should be the source that you're painting with with that history, the history brush. Now I personally don't use the history brush all that often, And that's because I instead decided to work non destructively by putting most of the changes I'm gonna make on separate layers by putting them on separate layers. If I wanted to undo something, I could either throw away that particular layer, or I could add a layer mask to it in paint there to temporarily hide things, and I find it to be much more versatile. But on occasion I'm doing something quickly. I end up working directly on the layer that contains the original picture, and I mess up in some way. They need to get back, and that's when I'm very happy that the history ah brush is available. Also, you can fill an area from history, So if I select an area like this just rectangular area, I can go to the edit menu. There's a choice called Phil and one of the choices in this menu is called history, and that means do the exact same thing is what the history brush did. And when you click OK, that brings it back to either what the original image looked like, or whatever you have the history brush set to in the history panel. The time I do that the most me revert this image to get the whole thing back is when I apply a filter. And afterwards I wish I remembered to duplicate a layer and apply it separately. Let me show you what I mean. I come in here and I choose. I don't know, uh, find edges and I get this interesting look. But I wish I would have duplicated the original layer first, so that then maybe I could mask this or I could change what's called the blending mode on it in just in the end, I wish I had the original picture in that Well, instead of starting over, what I will often do is I'll create a brand new empty layer by clicking on the new layer icon in my layers panel, and then I'll just tell Photoshopped to fill that layer, and I'll tell it to fill it with history, meaning? Fill it with what the image looked like when I first opened it. And then maybe I want that to be underneath so unlocked that bottom layer and drag it under. So now I can easily get to that point where it looks a ziff. I duplicated the layer because I just made a brand new empty layer and I filled from history. So now I can maybe use a blending mode. Just make it up use for it. Here and now, I have that filter applied in a different way.
