This is the banner for my YouTube channel.  To create this banner I took a picture consisting of a music wave with notes surrounding the wave.  I then went into Photoshop and added a few things.  I added a hue/saturation group which is where I turned the pictures saturation all the way to zero to turn the picture into black and white.  I then created an effect layer and put noise over the picture which gives the picture a grainy look.  I also added an overlay rectangle that I made see through gray and put my companies name over top.
