What is the Smudge Tool?

The Smudge tool is a Photoshop feature that allows you to mix or blend the content in an area of your image. You can use the Smudge Tool to push pixels in a given direction, causing them to become distorted. The effects are similar to what you get when brushing over a wet painting.

Think of It Like Paint

Imagine that you are painting a seashore image on a canvas. You want the blue of the water to slide gradually into the tan of the sand, so you use your brush to blend the colours together in that area of the painting. The colours mix and perhaps muddy a bit, and the result is a softer transition from one area of the picture to the next.

This is essentially how Photoshop’s Smudge tool works. Applying this tool to an area of your layout has a similar effect to rubbing a brush over wet paint. Only, instead of moving paint, you are manipulating an image’s pixels.

How Smudging Works in Photoshop

Smudging is not a one-size-fits-all process. With the Smudge tool, the point in the layout on which you click is the colour that you will be moving around the area. You can also choose the size of the brush that you use for smudging. A larger brush size will smudge a larger area than a small brush. Therefore, if you are doing precise work, it can be wise to size down. You can also select the strength of the effect. Make it stronger if you want a definite smudging effect or lighter for a barely-there smudge.

When to Use This Effect

This tool creates a smearing effect. It’s also handy for when you want to soften the edges of an image, though it works differently than the blur tool. Smudge can also be used all over the project to give it the look that it was crafted by hand. Done right, the finished layout may resemble an oil painting.

Another smart use for this Photoshop tool is to cover up small defects or blemishes. Smudge a nearby shade over the problem area so it will blend more readily into its surroundings. In the opposite way, smudge the dark colour from a shadow into the image to create definition or make body parts appear smaller.

As handy as the effect is, it is not appropriate for every situation. With the Smudge tool, detail is easily compromised or lost. Therefore, it should not be used when preserving detail is critical. Until you become familiar with this tool, it can be easy to apply too much smudge. When first trying it out, it may be a good idea to use a small brush size and a light setting and move slowly over a small area. After some practice, you may feel ready to use a larger brush or higher strength.

How I use the Smudge Tool

These two images I used the smudge tool to soften the edging. The elements like the little girl, bathtub and bear was digital art and is very contrasty and hard edges compared to the background. So I have to resort to the a few techniques such as the Smudge Tool or Blur Tool. I also use the Smudge Tool as a blending tool when creating my own Digital Textures.

Tip ~ When blending edges I tend to drop the strength, tick Sample all layers in the menu bar and work the edges on the elements I want to blend. There are a few ways to use the Smudge Tool.
