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.
