Selection And Modification Tools In Photoshop

Hello,
Today Harry told me that he wanted know how what are selection and modification tools in photoshop and how to use them. I told him what types of tools they are and where to use them. He got to very impressed that he wants to learn more. I explained him that photoshop provides three simple tools for selection: Marquee, Lasso and Magic Wand. They are located on he top of the toolbar. In addition, you can use commands on the Select menu.
The selection tools allow you to select a portion or a subset of an
image to work on. Most of Photoshop's other tools and filters can then be applied to this selected area, altering its color, shape, texture, position and/or other attributes, while leaving the rest of the image untouched.

The Marquee Tools are used to select a specific regularly shaped area. The marquee tools include the Rectangular, Elliptical, Single Row and Single Column Marquees.



The Lasso Tools are used to select an irregular area. These tools include the Lasso Tool, the Polygonal Lasso Tool and the Magnetic Lasso Tool.


The Magic Wand is used to select areas of an image based upon color. The Magic Wand does not have additional tools.


All of the selection tools may be used individually or in conjunction with each other to select exact areas of images. The Options Bar allows you to choose to add to or subtract from a previous selection.
If you choose New Selection, any currently active selection will go away.
If instead you would like to add to the current selection, or subtract from it, make that choice in the Options Bar. You can even choose to select an area formed by the intersection of your selections.

Selecting Gradient Colors

Hello,
Harry asked me that he was not able to understand the concept of how to select the gradient colors. I told him that you now how to select the gradient tool, (refer to the previous blogs)the gradient options appear on the Options Bar. The color bar allows you to set the, gradient colors. If you click on the pull down menu, you
you can select any of the displayed color combination. (If you hold your mouse over any of the choices, you will see a text description of it.) The upper left hand corner always displays the default combination, a gradient from the foreground color to the background color. By setting your foreground and background colors on the toolbox, you can easily define your own simple gradient.


The circle button with the black arrow (circled in red here) provides a fly-out menu with more gradient options. This menu lets you load more gradients, save modified gradients, gradients shapes, rename gradients and reset the gradient selection to Photoshop's default values. The bottom grouping is a list of other gradients families that can be used if desired by the user.


Editing Gradient Colors

If you want to make changes in one or more of the colors in your chosen gradient, you can click on it the options bar to open the Gradient Editor dialog box. For example, clicking on this gradient.


This will display this Gradient Editor dialog box :
The Color Stops appearing below the gradient marks of the each colors in the gradient. To change a color, double click on its Color Stop; the color picker will open, allowing you to select a new color. You can also add more Color Stops by clicking between the existing Stops. To remove a color, simply drag its Color Stop away from the gradient.

Saving an Image

Now that you've changed the image, let's save it: select Save from the File menu. Photoshop should select the directory from which the image was loaded and should choose Photoshop's PSD file format as the image format.

Knowing Gradient Styles

Hello,
Yesterday Bella told me that she is very confused with various types of Gradient styles.Then I told her in a simple way that when the Gradient tool is selected, a series of five style buttons appear on the Options Bar:
These buttons represent various gradient styles:

* Linear * Radial *Angular *Reflected * Diamond

The description of each style, with an example of which is shown below. To help you visualize how each gradient was
created, the mouse action is superimposed on the gradient:


* The black triangle indicates the center point.
* The dashed line indicates the selection line.
* The red triangle indicates the end point.

In each case, the mouse was dragged from the center point along the selection line to the end point, then released.

The Linear Gradient- This option can create vertical, horizontal and diagonal gradient.
For vertical gradients, draw a horizontal selection line (that is, drag the mouse left to right or vice verse)

For horizontal gradients, draw a vertical selection line (that is, drag the mouse up or down)

For diagonal gradients, draw a diagonal selection line (that is drag the mouse diagonally)



The Radial Gradient - This option creates circular gradients. Start the mouse drag at the point where you want the center of the gradient to be ; release the mouse button where you want to the outermost circle of the gradient to be.


The Angular Gradient - This option creates a circular sweep of blended color. Think of it as a clock face with a sweep second hand that the gradient flows from as it goes around. Start the mouse drag where you want the center of the clock free to be, drag the selection line as if you were drawing the starting point of the clock's second hand. When the mouse is released, the second hand sweeps counter-clockwise around the center point and stops when it returns to where it began. The sweep begins with the left-most color on the color bar and ends up with the right-most color.

The Reflected Gradient - This option works the same way as the Linear Gradient, but it creates a mirror image as well. In other words, when you create the selection line, the gradient flows out in both directions from the center point, rather that just in the direction you drag the mouse.

Gradients In Photoshop

Hello,
Yesterday Jake told me that he wanted to create a picture in which he could fill two or more colors but didn't knew that how is that possible. I then told him that is very easy in Photoshop using Gradients. He now got confused and asked what are gradients. I told him that a gradients is a fill
consisting of two or more colors blending together. I showed him this picture which is a simple example of a gradient, which is beginning with blue and ending with yellow:

He now got so very curious to know more about gradients that he asked me if I could tell him very thing about gradients.
So I told him that we will learning step by step. I started telling him how to create a gradient.
To Create A Gradient:


Step 1: Click on the Gradient tool. The Gradient tool is grouped together with Paint Bucket Tool in the toolbox. If the Gradient Tool is not shown in the Toolbox, simply point to the Paint Bucket Tool, press down the mouse button and select the Gradient Tool from the fly-out menu

Step 2: Select your style options. When the tool is selected, the Gradient options appear on the Options Bar. The buttons represent various available gradient styles.

Click the button for the style you want.

Step 3: Make your color selections. When the tool is selected, the Gradient options appear on the Options Bar. The color bar lets you choose the the gradient colors:
Select the colors you want.

Step 4: Indicate which layer you want. In the Layers Palette, select the layer on which you want to paint.

Step5: Select an area to fill. Using the selection tools, select the area of layer you want to fill.

Step 6: Draw the gradient. Point with the mouse to where you want the blending to begin (the center point), then drag the mouse to where you want the blending to end (the end point). This line is referred to as the selection line.
The area you selected in step 5 will fill with the gradient. The center point is always the left-most color on the color bar, the end point is always the right-most color on the color bar and the gradient is drawn in between.

Knowing and Understanding Vector Shapes

Hello,


In Photoshop, we can use the Vector Shapes tools to create an object for placement on our image. Vector Shapes are created based on mathematical calculations rather than a specific number and pattern of pixels, this allows them to be resized pixelated. Every time a vector shape is changed in any way, Photoshop redraws the image, filling in pixels as necessary therefore, no quality is lost.


The Vector Shape tools include the Rectangle tool, the Rounded Rectangle tool, the Ellipse tool, the Polygon tool, the Line tool, and the Custom Shape tool.The Custom Shape tool lets you select without causing the image to become jagged or



Creating A Vector Shape
Step I - Select a Vector Shape tool. The Vector Shape tools are located directly under the Type Tool in the Toolbox. The icon that appears in the location of the Toolbox corresponds to the last Vector Shape tool that you used. Click on the tool to select that shape, or hold down the mouse button and select a different shape from the fly-out menu. Once a Vector Shape tool is selected, the Options Bar will display a palette of the various shapes available.
Click on the desired tool if its not already selected.

Step II - Select the shape you want. If you have selected the Custom Shape tool, click the Shape pull-down menu in the Options Bar and the select the desired shape.
The circle button with the black arrow provides a fly out menu with more shape options.This menu lets you load more shapes, save modified shapes, delete shapes, rename shapes and reset shapes to Photoshop's defaults (among other things). The bottom grouping is a list of other shape families that you can use if you wish.

Step III - Choose the options you want for your shape. By clicking the down-arrow to the right of the palette of shapes on the Options Bar, you will see the the Options dialog box for the currently selected shape. Each shape has different options based upon what can be done with that shape. Below are the Options dialog boxes for each vector shape.




































Step IV - Draw the shape : If you have selected a shape with defined or fixed size, simply click the mouse button on the image and the shape will appear. Otherwise, drag the mouse to draw the shape.
Photoshop automatically creates a new shape layer a new shape layer for the first shape drawn, subsequent shapes can be drawn on the same layer. In order to create shapes on different layers, you must create the additional layers and make sure the correct layer is selected before creating additional shapes.

Step V - Edit the shape : To change the fill color of a Vector Shape, simply double - click on the color box on that shape's layer. The color picker will appear and the fill color can then be changed.

Using The Color Picker

Hello,
To display Adobe's Color Picker, click on either the foreground or background color in the toolbox. The color picker dialog box, shown below, allows you to select a very specific shade, either by visually choosing it or by defining the color numerically.

Visually - The initial white circle is the current color. Drag the little triangles on the vertical color slider to change the range of colors displayed, then click on the desired shade to select it.
Numerically - Enter the correct color code in the RGB, CMYK, HSB, Lab, or Hexadecimal (Web) text boxes.

When the 'ONLY WEB COLORS' box is checked in the bottom left - hand corner of the dialog box, Photoshop will only display colors that will properly display on the World Wide Web:

When you are satisfied with your selected color, click the OK button to return to the image.

Pull down the Book menu to select the desired color system. Scroll though the available colors using the color slider on the right, then click on the color you want. Click OK to return to you image, or click Picker to return to the Adobe Color Picker dialog box.
