Making a barcode

Hello, today i am going to be showing you how to make a barcode for the front cover of the magazine. Every magazine requires one as otherwise it's going to be free. There are only 4 steps to doing this as it isn't that hard. 

 Step 1:

Grab the rectangular marquee tool and go to the top of the screen where is says Style. Drop the box down and select Fixed size. Make the width 100, and the height 1. Then click on the screen and a small box should appear.

Step 2:

Fill in the box with the colour black using the paint bucket tool. But make sure that your background layer is selected beforehand otherwise it won't fill the box in.

 

Step 3:

Once that is done, go up to the top of the screen again and select filter, then noise and add noise. Making sure that the amount is up to full capacity, Gaussion is selected and monochrome is turned on, proceed to press okay.

Step 4:

Then using the selection tool, click on the now monochromed bar, and select show selection marks at the top of the screen. Continue to drag the bar down until it is the correct size or to whatever size you prefer.
