Photoshop that great tool that despite being one of the longest, is still perhaps the most effective in the world (like a good wine). This has many very useful features, one of them being its drafts. That is why in today’s appointment you will learn what it is for and how the background eraser tool is used in Photoshop.
It sounds absurd if you have never used Photoshop, to talk about its eraser and also in the plural, but believe it or not, the eraser in this application is one of the very important tools.
Therefore, this means that you must learn to use the Adobe Photoshop toolbar correctly by familiarizing yourself with any of its elements.
Photoshop eraser a thousand times more useful than Paint’s
What you read in the title is obviously a joke, but it’s not that far from reality. The eraser tool in Photoshop has many super useful functions, when it comes to editing, but before you know what it is for and how the background eraser tool is used, first know a little about the normal one.
Knowing what the Photoshop tools are for, what the eraser does is change the pixels to transparent or to the color of the background of the image. If you are working with a layer that has transparency locked, they change to the color of the background, otherwise they become transparent.
To use it you have to select the “Eraser Tool” in the bar (if you are working with a layer whose transparency is locked then you have to define the background color).
Then for the next step it is necessary to explain first, that the eraser is defined for what I acted as the brush or the pencil. Therefore then you must choose the mode settings.
To adjust the brush or pencil mode, you have to go to the top bar where they are, and define the opacity and the flow that the eraser will have (they come out right there, you don’t have to look much).
Eraser at 100% or maximum will remove all pixels, while lower will partially erase them. Finally, you just have to drag the eraser over the area in question and it will obviously perform its function immediately and efficiently.
What is the background eraser tool for and how is it used?
Now if what you came for, first you have to say that the background eraser tool (which is part of the same eraser), what it does is that it erases the pixels of a layer that has transparencies (while dragging it).
This through specific ranges of tolerance and sampling, are responsible for controlling the sharpness and range of transparency limits. Also, you can keep the edges of an image in the foreground while blurring its background.
It favors the creation of architectural plans in Photoshop, allowing a better finish to be finalized, erasing details that are not aesthetic for the final result.
Also, in the center of the brush it samples the color (in the so-called hotspot), removing that color wherever it appears inside the brush. And in turn it extracts the colors on the edges of the front objects, in this way if the object is pasted to another image the color halos will not be visible.
How is it used?
With the above, you already have an idea of what it is for and how the background eraser tool is used? Or well at least what it is for, because now to finish you will learn how it is used.
In the layers panel, select the layer that you will erase, then choose the “Background eraser tool”, for this go to the “Eraser tool”, and keep it pressed until a panel displays the desired option, press it.
Once chosen, go to the brush sample and define the draft (hardness, roundness, angle, spacing, diameter, among others). Then you have to choose the following options, if it is in the tolerance, define if you want it to be high or low (the high one erases a large extension of colors, the low one the colors most similar to the one you have in the sample)
There is also the erase limits mode, this has three options, the non-contiguous one that erases all the areas with the sampled color, contiguous to erase the spaces with that same color but that are connected, and find edges to also erase the connected areas but keeping the sharpness of the edges. And ready the question, what is it for and how is the background eraser tool used? It has been fully answered.
