Technical Separate Objects From Background

Wanderer exist on many sect split from the audience, prominent in the sect that uses magic wand, QuickMask, Magnetic Lasso, Pen Tool and the Extract filter. In the fourth sect that is hard to say what is the sect of Buddhism sect which is also described direct eagle subjects.

Because each of the sections depends very much on the object to be cut, and whether it is the contrast or not? Data subjects should be cut too much detail or not? vv. Therefore in this article, I will guide you to the four sections.

Start with the simplest method and most rarely used.

Using the Magic Wand

Magic is only used when the object to be separated and the extremely high contrast such as objects placed on a monochrome background (dark or light) and subjects with high contrast image. In the example below you see the object to be split fairly dark tones and a white background, so in this case, the quickest way is to use the Magic Wand.
Any action related to image editing, we always work with a copy of the original image, because what they have flaws which go back to "mother country". So you double the original image layer by pressing Ctrl-J.
Magic Wand tool in the toolbox, the default value of Tolerance is 32. Tolerance value to adjust for "eat" the tool when the object is and the contrast difference.  Background and object contrast lower the Tolerance higher value and vice versa. In this example the default value is enough.
Click once on the white. You'll see it appear a selection. This region is the selection of the background and not the object to select, so you have to inverse the selection by pressing Ctrl-Shift-I. After you click finish press Ctrl-J to copy the selection to a different layer.
That's it!  you have done and then separated.

Magnetic Lasso tool:

This is a powerful tool used to cut image, but it also depends on the contrast of the background and the object to be separated. This tool works by automatically creating anchor points on the adhesive border of the object when you mouse around the object.  In this case, you can use the Magnetic Lasso tool and the result is quite good.
Magnetic Lasso tool and start clicking a point on any image.  Then drag the mouse along the border of the image.

Note that if you are unfortunately beyond the short or in the audience, you can press the Delete key on your keyboard to return to the previous point.
To continue so until you make a selection closed.
Press Ctrl-J to copy the selection you have the following results.

Using QuickMask
This method has two advantages over the above is not dependent on the contrast of the image, but there are disadvantages to narrow down the course and take over. This method mainly used Brush and Eraser to make the selection. You will be shown in color on a class object to mark the areas to separate.
To start you press Q to enter QuickMask mode. Then select the Brush large bowl inside the object.
Shortcuts to change brush size is key square brackets] and key [.
Factors to all areas within the object.
Then you zoom up and use the brush size to not less than for those positions alternates.
When you press Q factors done again to exit the mode QuickMask. There will be a selection occurs, but only select around. Work is now the inverse it and copy is complete.  Press Ctrl-Shift-I to inverse and press Ctrl-J to separate objects.
Pen tool.
As the experience of many people, the Pen tool is used most widely and most professional to separate an image, because the roads often cut fine as Sunsilk and results high. However, you must be very proficient with Photoshop, or at least as much about understanding Pen tool.
Pen tool
Setting on the tool options as shown
Create an anchor point on the first. Click the next point and immediately bent so that it fit border, if you release the mouse button to select your tool to Convert Point Tool bending, left bending immediately if you do not need to.
Once happy with the way the first line you continue Monday
These points are circled in the picture below is very important that you use to bending, Leveler, opaque, plastic, trim it to fit the object.
When you start back at the way you have created a path around the object and finally press Ctrl-Enter to switch paths to the selection.
Và nhấn Ctrl-J để tách đối tượng. And press Ctrl-J to separate objects.

Impressive results?
Also a filter using the Extract just the opposite of using QuickMask, rather than shown inside the object is shown in the external borders. So my instructions this way again you can research. Bộ lọc Extract ở Filter > Extract. Extract filter in Filter> Extract.

However, this filter works to form a border separating the complex as fur, hair flowers grass may or women ....  but also the tools to bundle projection Piec Pen.
