Concept: The lesson is designed using Adobe Photoshop. We have used selections, different combination of image editing tools and filters for most of the effects. Photoshop comes up with lots of the options and scope for experiment is much more than you can imagine. We wish to encourage you to use different options and tools to get better output. The lessons and techniques described need to be followed as a guideline to achieve the effect.
1. Open Photoshop. Open Image to work with layer masking
basics.

2. Please understand the concept carefully. When you
open the image the default layer is "Background" and it
is locked. Masking option is not activated in this condition. You
need to unlock the layer.
3. Double click and rename the layer to unlock it.
If you don't name it, it will take Layer 0 as a default name.

4. Using Elliptical Marquee tool, select the middle
portion of an image.

5. Layer > Layer Mask
> Reveal Selection.
Since the image has only one layer, it will be as follows before
saving.

6. The layer will show the masking
thumbnail.

7. The portion selected by the Elliptical Marquee
tool is revealed and rest of the portion of the image is hidden
by the mask. Here is the final image after saving it in Jpeg format.
