An image on a computer is built up by pixels, normally they're so small so we don't see them until we zoom real close, but they are there. Here's a cool trick if you want show the pixels more and perhaps create an transition from normal on one side and pixels on the otherside.. Kind of an effect that show the image is digital.

I'll explain how you can acheive that effect below:

1. Open your image in Adobe Photoshop

2. Duplicate the image by pressing CMD-J or do go to the layers window and right-click on the layer and choose duplicate.

3. Now you got two copies of the image.. Goto Filter >> Pixelate >> Mosaic

4. Now you've got the mosaic window up.. You'll see a slidebar in here in order to increase or decrease the level of square size..

5. Choose a size and press OK.. Now you've got one layer with the orginal and one layer which is full of pixels..

6. Time todo the trick.. Press the layer mask button in the layer window at the bottom of the window and you'll now see it's empty..

7. Now goto to Gradient tool in the toolbox and choose to use the gradient black/white usually is 3rd from the left on the top..

8. Now you've gotta use the tool.. Just simply drag it from the side and volá one side is digital pixelated and one is looking normal..

I choosed todo this effect on a girls face.. But it's only your imagination that stops you!
