How to Use the History Brush Tool in Photoshop?
Adobe Photoshop is a raster-based image editing software. It is developed by Adobe.Inc and available for both macOS and Windows operating systems. You can use Photoshop to create or edit images, posters, banners, logos, invitation cards, and various types of graphic designing work. While working in Photoshop, in many situations we have faced that we have done some miserable and our whole work is damaged or turned awkward. So, we just want to undo that change but not at the full image but at some parts of the image where things are not according to our will. This cannot be done through simple undo because undo will undo all the changes and also undo cannot be done more than 1 time in Photoshop(it may be done up to 10 times if we change the settings). Here comes the use of the History brush tool.
History Brush tool helps us to multiple states of an image. It gives us the option of doing multiple undo’s all at once. It allows us to do undo on specific parts of the image according to our needs and requirement. It is useful to create many effects. This tool is specially used by professional photographers for doing advanced editing where they need to go back in history in some parts of the image. But before understanding the history brush tool, let’s first understand the History panel in Photoshop.

What is the history panel in Photoshop?
History Panel in Photoshop is a panel showing the history or log of all the operations done in the current Photoshop file from the starting. You can open the history panel from the Window menu => History or from the right side of the documents as shown below:
As you can see from the above image, the history panel shows all the changes and works that we have done in the current Photoshop file. Now, there is a small icon marked in red in the above image is the snapshot button. This button helps us to take a snapshot at a particular point in the entire session of a Photoshop document. It can be understood as a point from which the user can start its work if anything goes wrong or damages instead of starting from the first.

Now, suppose we want to save this state i.e now if we apply any other changes and apply the History Brush tool then it will return back to this state. This can be done through the snapshot button in the History Panel. Let’s see how to do it.

By default, the mode is set to Normal. You can select modes according to your requirement.
2. Opacity: The opacity determines the opacity of the brush. It has a value in the range from 0-100%. By default, the opacity of the brush is set to 100%.
3. Flow: The flow determines the flow of the brush effect (color in the case of the normal brush).
