Coming to you from Beyond Photography, this awesome video tutorial will show you the ins and outs of aperture and how to use it to create images with better technical quality and to take more creative control over your photos. In tandem with shutter speed and ISO, aperture is one of the three exposure parameters about which you must make decisions for every photo you take. It helps control the literal exposure of the image, but it is arguably the exposure parameter that has the greatest creative impact, as it helps determine the depth of field (how much of the image is sharply in focus), which allows you to keep everything from front to back sharp or keep only your subject in focus to easily isolate them and draw the viewer's eye. Check out the video above for the full rundown.
