Photoshop Effects - Sphere

Here I am going to describe a quite simple technique to create a sphere with some effects. Go to the File menu: File>New and create a new file RGB of 5x5 cm with black background.

In the tool bar select the Elliptical Marquee Tool and draw a circle.

In the icon of the Standard Colors in the tool bar select blue for the background and white for the front.

Still in the tool bar select the Radial Gradient Tool.

Move the mouse inside the circle for two centimeters starting with the upper right corner and finish at the lower left corner. You must have created something quite similar to the example bellow. The blue part of the picture should remain selected until the end of the task.

Go to the Filter menu: Filter>Blur>Gaussian Blur with 9 Radius and click on Ok.

With the effect just applied your task must be quite similar to the example below.

Now, the final retouching still in the Filter menu: Filter>Lighting Effects with the following ones co-ordinated: Style Default, Light Type Spotlight, Negative 50, Focus 88, Gloss -86, Material 100, Exposure -15, Ambience -17, None. Now, Your task is ready.

If you wish; starting from here; you can try to repeat the example below. It's really worth trying.
