Yeah, couldn't think of a very good title. I got the red on the berry by covering my white flash, but keeping the red light uncovered. Yay for originality. However, what I /really/ like about this pic is...I GOT THE BACKGROUND OUT OF FOCUS!!!! Yeah! I've been trying to figure that one out for /ages/.
Aperture (oops, I spelled it wrong in my previous message) is the size of the opening in your camera's lens. This is one way that a camera uses to control how much light reaches the sensor (or film). The size of the aperture is commonly called the f-stop. Strangely enough, the larger the opening, the smaller the f-stop number so f/2.8 represents a larger opening than say f/4. In addition to controlling the amount of light that the lens admits, the aperture is used to control the Depth of Field of an image. That is, which parts of an image are in focus and which are out of focus. The larger the aperture, the smaller the depth of field. Your picture has the background out of focus while the berry is in focus thus your camera has created a small Depth of Field. You can control this yourself by setting your camera to use a large aperture (small f-stop). The largest aperture on your Canon A80 is f/2.8. To manually set this you would use the Av (Aperture value) setting on the Mode dial (your camera manual will come in handy here).
