Hi, I'm Dan Reinecke with Unknown Media, and today I'm going to share with you the difference between aperture and time value. Aperture is going to be referring to the diameter of the lens's iris and the time value, better known as shutter speed is going to be referring to how long the shutter stays open to expose your image. Both of these will affect the light coming into the camera. The larger the iris is on your camera, the more light that will be let in. With that, the longer your shutter is open, the more light that will be let in. It can be a bit confusing because we're dealing with fractions. A shutter speed of say 200 is actually a faster shutter speed than 50 because we are referring to fractions of a second. So, a time value of 200 actually means the shutter is open for 200ths of a second and an aperture of two is actually a larger diameter than an aperture of 22. This can all get a bit confusing, but the one thing to know is that the more open the aperture is, or the longer the shutter is opened, the more light that will be let in to expose your image. I'm Dan Reinecke, take your best shot.
