In the process of image editing in a graphics program, one of the most frequently used operations are perhaps the selection and cutting of the objects is performed to move them, transform, correction, removal from the background, and so on. D.
the Interneta lot of graphic editors, but learned well how to select an object in the "Photoshop", it will be easy to deal with this and all other programs or online services.
If you say that in terms of variety and convenience way to highlight "Photoshop" has no equal, it would not be an exaggeration (at least explicitly).
Allocate can manually scanning the contour of an object by drawing a marquee or a brush, and automatically, using standard figures highlight the contours and other "magic" tools.Furthermore, to isolate fragments "Photoshop" uses masks, color channels, filters and special plug-ins.
However, despite the variety, simplicity and convenience of the special selection tools in the "Photoshop", according to many venerable "fotoshoperov", more and better than using the "pen" (Pen tool), there is no way.
By carefully outlined the pen contour object knock the right mouse button and choose the command "Make Selection" (Make Selection), then in the dialog box set the feather radius, put / removed tick in checkbox "Smooth" (Anti-aliasing) and pressOK.All selection is ready.
Automatic selection of the object in the "Photoshop" is reduced to stretching frames along the contour of the item if it has a rectangular or oval shape, and in some instruments to click (click) mouse inside the selected area.
Rectangular and circular selection
Selection Tools rectangles, ellipses (circles) and narrow stripes (lines) assembled on the panel into a group with a prompt "rectangular area" (Rectangular Marquee Tool), which, in addition to the title, includes tools"Elliptical Marquee" (Elliptical Marquee Tool), "Field of the horizontal line" (Single Row Marquee Tool) and "Field of the vertical line" (Single Column Marquee Tool).
To make a selection, you click where you have, the mouse, a frame to stretch the desired size and release the button - the selection is ready.If you drag the mouse while pressing Shift, turn the square (or circle), and if the key to Alt, the frame will stretch from the center of the figure, not on the corner or edge.Next
very useful "if" is connected with the space bar, which is clicking during selection (hold down Shift), you can interrupt the process of stretching the frame and move the entire path to better "aim", then release the space bar and continue the selection.
And the last "if" refers to the cursor, which is inside the selection area changes its appearance to indicate that the circuit can now be moved in its entirety.
options settings all selected on the panel at the top of the same, except for the oval selection, for which a mode of "smoothing" (Anti-aliased) to smooth the transition of opacity on the edges.
complex contours highlight
dealt with how to select an object in the "Photoshop", if the contours of the allocation are rectangular or oval (round) shape, you can move to a more intelligent allocation of funds.
For elements with complex contours offers provided by a group of tools with a prompt "rectilinear / Polygonal Lasso" (Polygonal Lasso Tool), which, in addition to the aforesaid, includes tools "Lasso" (Lasso Tool) and "Magnetic Lasso"(Magnetic Lasso Tool).
Simple "Lasso" is like a pencil.By clicking the left mouse button, encircle (throw a lasso) the desired area (object) and release the button.The circuit will be closed automatically, no matter where you release the button.If the path has failed, you can, without releasing the button, press Esc, removing thus the selection, and "throw a lasso" again.
including 'Straight-line / Polygonal Lasso ", you stroke the object is not a smooth, continuous line and angular contour series by clicking the mouse from point to point, which stretches between the straight lines.To close the loop is not necessary to combine the beginning of the end point - quite close to it so that the cursor appears next to the circle, alluding to the fact that you can safely click - circuit closes.Create contour, not closing it completely, and you can double-click or by pressing Ctrl.
If the line does not go back to rescue key Esc, but it is better to use the button Delete, removes the last segment of the path.From down in the course of both the Alt key selection lasso change roles.
If you would still like to cut out an object in the "Photoshop" as long as the selection was more or less quality and, most importantly, fast, then perhaps the "Magnetic Lasso" handle it well.
wise "Lasso Magnet" itself recognizes the line of maximum difference in color, brightness and contrast, and "sticks" to that line.We are required only to click on an object allocation and just "put a lasso" around it, not bothered to detail.Unlike conventional lasso, magnetic "lasso" need to set the width (width) band (strip), he should analyze in determining the boundaries of allocated object.The contour of the magnetic tool is closed in the same way as conventional lasso.
"Magic" tools
Another "sweet couple" funds allocation, hidden under a single button on the toolbar includes tools "Magic Wand" (Magic Wand Tool) and "Quick Selection" (Quick Selection).These tools allow you to highlight the image area of the same color or colors of similar tone.
"magic wand", in contrast to the familiar tool "Fill" (a bucket of paint) with the same settings does not fill portions of different color and makes them stand out.Obeying the click of a mouse in any point, "Magic Wand" analyzes the color around it and highlights all the related areas of the same color with the proviso that in the settings of the tool is set to "Related pixels" (Contiguous).Otherwise, the selection will spread to all suitable areas of the image.
tool "Quick Selection" works on the same principle, except that here the selection draw its own brush with adjustable parameters (size, hardness, spacing, angle and shape).
There are many reasons why the use of standard selection tools in certain situations, inappropriate or undesirable, so it is advisable to figure out how to select the object in the "Photoshop" in such a capricious way.
For this purpose, a group of erasing instruments (erasers), among which there are also "wizards".The group includes the actual "Eraser" (Eraser Tool), "Background Eraser" (Background Erser Tool) and "Magic Eraser" (Magic Eraser Tool).
essence selection of objects using the eraser is obvious and simple: every element allocated around completely (or with a smooth transition) is deleted, then the removal of the object will not be difficult.
"Eraser" works like a brush or pencil, so they have the same settings.The principle of "magic eraser" is the same as the tool "magic wand", but the eraser does not produce selection and removes the picture or part of the field of the same color.
"Background Eraser", though not magical, but if you show him a sample (click the mouse over the area to be removed) and hold the button to cut around the object, it deletes it what you want, regardless of the complexity of the border, and even generously allow you to"brazen" climb cursor-eye on the subject.
Alternatively, highlight color can be seen the command "Color Range" (Color Range) in the "Allocation" (Select).This command opens a window parameter settings of this function with a reduced copy of the image in the center.The color that should be allocated to indicate, by clicking the mouse (pipette) on the preview image or in the image itself.You can click "before losing momentum" until the selected shade does not suit you, and if clicking a button Shift, a new color be added to the previously selected, and click with the key Alt, on the other hand, excludes the specified shade of the candidates for the selection (the same is donepipette +/-).
to control the release of multi-colored field to choose a miniature radio "selected area" (Selection).
Extract an object from its background
The task of separation of the object from the background, "Photoshop" an excellent job for the team "Extract" (Extract) in the "Filter" (Filter).This command takes us to a separate dialog box, mini-worthy status editor selections.We are required to select the top left like a pen tool, set the stroke thickness and cut around the object, thus indicating the program, which will host the boundary between the discharge element and the background.Border have to be drawn inside the lines bordering the object.Closing the loop, choose the paint bucket (Fill Tool) and fill the object by clicking inside (not outside!) Draw the outline.Only then "OK" button will allow push yourself and make exceptional abilities filter Extract.
Isolation using color channels
To select objects with very complex configuration is sometimes resorted to using color channels as select an object in the "Photoshop", it turns out, can not only standard methods.
To do this in the Layers Panel go to the "Channels" (Channels) and choose the most contrasting (usually blue) channel.Then duplicate the layer of the selected channel, go to the "Image" (Image) & gt;"Correction" (Adjustments) & gt;"Brightness" (Brightness) / "Contrast" (Contrast) and increase both parameters, maximum blackened object and "bleaching" background.If necessary, you can make more accurate black or white brush.
Next image invert (Invert), select this command in the same menu, the "Image" & gt;"Correction".Now you just click with the Ctrl key on the channel layer, and a copy of "shutting him glazik" to return to the "Layers" in the mode of RGB, where you have been waiting for an accurate and precise selection.
Selection using the "Quick Mask"
You can select / cut the object and using the "Quick Mask" (Quick selection tool), located at the bottom of the toolbar.The selection is here merely paint in black (but masks the color red) with the help of traditional brushes.Selection for shading its boundaries turns out not only variations in stiffness, opacity and brush pressure, and painting various shades of gray.In the mask can be applied to a gradient fill "from black to white," or vice versa.
Moving taking into account the contents of
Often there is a need for some reasons a little move the object in the image.Such an operation is best done in a relatively uniform background, it was easier to "patch a hole" in the old place of the displaced fragment.It turns out that there is a program in which it is done almost automatically, "without noise and dust."For example, you can cut the object in the "Photoshop" CS6 and "quietly" move it to another location using the "Move the contents taking into account" (Content-Aware Move Tool), which is located in the instrument cluster "Spot Healing Brush."
To do this, select the object in any way and simply move to the desired location, and only the program will take care of that on the background of no traces (in any case, express) the previous residence "migrant".If you get dirty, tool "Moving in view of the contents" can help "cover their tracks" by selecting "Edit" command "Fill" and pointing in the "Use" option "Given the content."For clarification
edge isolation
Since version CS5 in "Photoshop" appears powerful tool "Refine Edge" (Refine Edge), located among other parameters on the panel settings all these tools.With this tool, you can set the width of the edge detection (setting "Radius" and the function "Smart range") and adjust the offset parameters, smoothing, shading and contrast borders to select objects.
