The Rule of Thirds
This tutorial is more of one related to composition than to a specific technique. The Rule of Thirds is a principle of composition used for centuries by artists and photographers. The underlying principle is really very easy to understand and use. In photography, using this The Rule of Thirds keeps the main subject off center, away from the middle of the frame. As a result, a photo looks more dynamic and interesting. The Rule of Thirds envisions two horizontal and two vertical lines trisecting an image with four intersecting points. You place your main subject where the lines intersect rather than centered in the frame. For example, placing the horizon on an upper or lower line helps create a well-composed landscape photo. For portraits, placing person where lines intersect vertically produces a more compelling photo. Now, to use the rule of the thirds, you need to know what resolution you want the image. I’ve chosen 1024×768. So create a new document with these values.
Now let’s create a grid to help us see the main focus points better. Go to Edit > Preferences > Guides,Grid & Slices.
In the menu, because we want the canvas devided in 3, we will ask Photoshop to put a Gridline every 33% of the canvas
You’ll have something like this: (if you don’t see the gridlines, go to View > Show > Grid).
Now observe that the black dots I added there are your main focus points. So don’t put your main subject in the center. This is the trick you would have to use when shooting with your camera, but if you don’t have the time to do that, you’ll crop your image using this technique.
Now open your image. Observe that I didn’t have the time to use this rule when I shot this photo. The main subject is in the very center of the photo. Now double click the background layer to make it a simple layer. Drag the photo layer in the other document you prepared.
Now scale or position the photo to bring the subject to your interest focus points, like me.

Creating a barcode
Create a new document, 1000×1000 pixels, white background.
Make a new layer and with the rectangle marquee tool make a rectangle. Fill it with white.
Go to Filter > Noise > Add noise. Add about 50-60% amount, gaussian and monochromatic.
With the selection still on, go to Filter > Pixelate > Crystalize and give it an amount of 10 to the cell size.
After doing so, double click on the noise layer to enter the layer style options. Now drag the slider like in my example to get rid of the grey points.
Now deselect (CTRL+D) and go and select the “single row marquee tool” and click on the middle of the selection like in my example.
Press CTRL+T to enter the free transform mode. Drag from the center of the selection down and hit OK. You’ll end up with something like this:
Now delete the other noise points that are left in order to remain only the lines. Here it is:
Now duplicate the layer several times and move them a little to the left or to the right.
Now select all the layers but the background and press CTRL+E to merge them all. On this layer make a rectangular selection and press DELETE. In this blank field type a random number. You’re

done:
