Today we look at tools of the graphic editor Photoshop - "Quick Selection" and its modifier "Magic Wand" . These tools allow us to make a quick selection of objects or fragments thereof, with just one click. But not everything is so simple and easy as it may seem at first glance. About the features of these tools will be discussed in this article.
Tool «Quick Selection» , the call - the Latin letter «W». This Tool «likes" homogeneous tone areas see the video on the left. But the area gradient for it too is not a hindrance. See the video below. Everything depends on what peripherals selected area. If the periphery is uniform, as in this case, the field selection is quick and easy, as shown in the lower video. But if the periphery is non-uniform, with similar in tone/color regions, the allocation will be the whole series of subtractions and additions.
For each case, you must select the diameter of the brush - the radius of coverage. The smaller the radius of the coverage - the more accurate the tool will generate the desired area. Conversely, the larger the radius of coverage (greater diameter of the brush) - the lower the accuracy of the allocation. Trying to find a tool in the selected area similar in tone and/or color pixels that fall within the radius of the brush (the cursor in the form of a circle with a cross in the middle). Find Similar pixels near the cursor, it adds them to the selection. By changing the diameter of the brush, we can adjust the accuracy of the allocation. Brush settings are carried out with the help of the parameters.
Tool «Magic Wand» , the call - the Latin letter «W». This tool works almost the same as the previous one, but more gently, I think. Video on the left, is shown as a single click, you can select the area. Someone asks: - "Why, then, all these lasso selection and fast, if you can so easily allocate the desired area?" Tool «magic wand» to someone may seem really magical, because the object allocates almost instantly.
I could say: - "That's what she and the magic...", so to speak but unfortunately I can not. This tool is not always true to its name. When it comes to the allocation of a dark subject against a dark background, this tool is powerless. He can not in a moment highlight dark in the dark, or similar objects in tone. This can only be done manually using the Tool «Lasso».
With the tool options bar "Magic Wand", we can in some way affect the validity of selection, changing some settings, such as setting "tolerance." This is effective for large areas with a similar tone, for example, white background portrait. But if you want to highlight, for example, the model's hair on an inhomogeneous background, there will have to use other methods of allocation, which will discuss in future articles.
In tools "Quick Selection" and "Magic Wand" has advanced configuration parameters selection. By clicking on the button "Refine Edge", see Screenshot on the left, a window opens with advanced parameters these instruments - the screenshot below.
Here you can choose to view the selected area, and set the edge selection. Moving sliders parameters, you can apply some effects to this selection. View mode is very useful when allocating difficult areas where you need to just select any area.
Tools Photoshop "Quick Selection" and "Magic Wand" can be good helpers for editing images, if you learn to use them wisely. These tools we have many more times will return in the next article in this series; will examine in more detail the principles of these tools in conjunction with other tools of the graphic editor Photoshop CS.
Today is all, thank you for your attention.
