How to Quickly and Easily Remove a Background in Photoshop

How to Quickly and Easily Remove a Background in Photoshop

This article on how to remove a background in Photoshop remains one of our most popular posts and was updated in 2019 for Adobe Photoshop 2020.

Photoshop offers many different techniques for removing a background from an image. For simple backgrounds, using the standard magic wand tool to select and delete the background may well be more than adequate. For more complicated backgrounds, you might use the Background Eraser tool.

The Background Eraser Tool

The Background Eraser tool samples the color at the center of the brush and then deletes pixels of a similar color as you "paint". The tool isn’t too difficult to get the hang of. Let me show you how it works.

Remove a Background, Step 1: Open your Image

Start by grabbing an image that you want to remove the background from. I'll be using the image below, as it features areas that range from easy removal through to more challenging spots. I snagged this one for free from Unsplash.

Now let's open it in Photoshop.

Remove a Background, Step 2: Select Background Eraser

Select the Background Eraser tool from the Photoshop toolbox. It may be hidden beneath the Eraser tool. If it is, simply click and hold the Eraser tool to reveal it. Alternatively, you can press Shift + E to cycle through all the eraser tools to get to the Background Eraser. If you had the default Eraser tool selected, press Shift + E twice to select the Background Eraser Tool.

Remove a Background, Step 3: Tune Your Tool Settings

On the tool options bar at the top of the screen, select a round, hard brush. The most appropriate brush size will vary depending on the image you're working on. Use the square bracket key ([ or ]) for quickly scaling your brush size.

Alternatively, you can right-click your mouse anywhere on the artboard to change the size and hardness of your brush too.

Next, on the tool options bar, make sure Sampling is set to Continuous (it’s the first of the three icons), the Limits to Find Edges* and the *Tolerance has a range of 20-25%.

Note: a lower tolerance means the eraser will pick up on fewer color variations. While a higher tolerance expands the range of colors your eraser will select.

Remove a Background, Step 4: Begin Erasing

Bring your brush over your background and begin to erase. You should see a brush-sized circle with small crosshairs in the center. The crosshairs show the "hotspot" and delete that color wherever it appears inside the brush area. It also performs smart color extraction at the edges of any foreground objects to remove “color halos” that might otherwise be visible if the foreground object is overlaid onto another background.

beginning the process

When erasing, zoom up your work area and try to keep the crosshairs from overlapping on the edge of your foreground. It's likely that you’ll need to reduce the size of the brush in some places to ensure that you don't accidentally erase part of your foreground subject.

In this guide, you’ll learn how to take advantage of Visual Studio Code to supercharge your development workflow. This article is written for beginners who may be using Visual Studio Code for the first time. VS Code, as it’s commonly known, is considered a "lightweight" code editor.

Despite the "lightweight" term, VS Code offers a massive number of features which keep increasing and improving with every new update. For this guide, we'll cover the most popularly used features. Every programmer has their own tool set which they keep updating whenever new workflows are discovered. If you want to learn every tool and feature VS Code has to offer, check out their official documentation . In addition, you may want to keep track of updates for new and improved features.

6+ Best Websites for Free Fonts in 2020

I firmly believe that, in order to strike the optimal balance between minimalism and visual appeal, a user interface should display no more than what’s absolutely necessary while making those necessary elements look visually appealing. Keep it simple, but make the simple look amazing. But, what does simple look like exactly? Well, strip away all of the over-the-top marketing gimmicks, redundant features, and cluttering visuals, and most of what’s left is the UI copy and text content. As boring as this sounds, let’s be honest: this is the most important aspect of any app or website. Information and the ability to navigate it is the entire reason users are using our app or website. So with the right typeface coupled with the right font styles (see “ Font vs typeface: the ultimate guide ”), we can create designs that are quite simple and yet visually appealing at the same time. This emphasizes the most important aspects of the design while usin

How to Contribute to Open Source TypeScript Projects

If you think of the ideas of open source applied to information in an encyclopedia, you get to Wikipedia – lots and lots of small contributions that bubble up to something that’s meaningful. – Matt Mullenweg One of my favorite aspects of open source is the fact that anyone can contribute! It’s like “productive volunteering” (if you’ll humor me). It’s a fantastic way to build something bigger than you, give back to the community, and level up your skills. In this article, we’re going to talk about practical ways for you to get involved in open source TypeScript projects. We’ll first cover assessing your level then jump into how you can find opportunities. Assessing Your Level Before you get started contributing to open source, you want to find your comfort level. Where are you at skill-wise? What level of complexity are you wanting to solve? How much time do you want to spend? These are important questions to consider before diving in. This
