Step 1: Choose an Image With an Unwanted Background In this example, I have a background of a football on one layer and, on another layer, the logo of my favorite college football team—OU, otherwise known as the Oklahoma Sooners. As you can see, the logo is surrounded by all white (Figure 1, below). 
Granted, in this example, it would be pretty simple to just select the white area and delete it, but let me show you another way to do it that might work for you when you don’t have that convenience (or time). Step 2: Scroll Through Your Mode Options Look at the top of your layers palette. The default setting is displayed as “Normal.” This is the layer mode. If you click the drop-down arrow, you’ll see a long list of options (Figure 2, below). (Note: Each newer version of Photoshop has added to this list, so if you’re looking at a pre-CS4 version, your screen may be slightly different from what you see in this example.) 
You can scroll through the list and change it to any other selection, or simply double-click the word “Normal” with your layer selected. Then you can use your arrow keys to scroll down the list and preview what the results are. Step 3: Choose a Mode That Works for Your Image In my example, I chose the selection “Darker Color,” and the white instantly went away (Figure 3, below). Choosing something like “Linear Burn” made the logo go black. So again, it’s all about trial and error. Some experiments just won’t look good, while others may be just what you’re searching for. 
While I often use this technique for logos, I also use it many times for photos as well. Mixing modes with imagery can result in some really stunning looks. Give it a try to see what I mean. Don’t forget that modes extend into the Adobe After Effects world as well. You can achieve some killer looks by simply changing the modes of your layers in After Effects! One last note: I realize this isn’t always the solution that works, and there will be times where your background may be too dark for this to look right. However, it’s at least worth a shot before taking the larger steps of trying to extract a logo from the background. Best of luck!
