[MUSIC PLAYING] In this lesson, we'll learn about raw images, also called Camera RAW. When we take a picture with a camera, there's a sensor that converts light into color information. To output a regular jpeg image, the camera then takes this raw sensory data and processes it into an image that we can actually see. Now this processing compresses our image and it results in a loss of the data. The camera removes lighting information mostly from the high and low ends of the dynamic range. If you'd like to learn more about high dynamic ranges and what they mean, check out our visual guide to high dynamic range images. The information stored in this range is very valuable if we want to keep detail in the bright or dark areas, as well as giving us greater ability to edit the photo after we've captured it. By outputting a Camera RAW image instead of-- or alongside of-- a normal jpeg image, we can keep all of sensory data that was captured. When we take this raw image into a photo editing application, we can actually begin changing attributes like the exposure, the white balance, contrast, and so on. Because the raw image format contains much more data, we can push these values further while actually maintaining image quality. Now raw images do take up more space on your memory card, so you will be able to take fewer pictures when outputting raw images. The editing ability and the dynamic range of raw files more than makes up for this little disadvantage. So remember, if your camera supports outputting raw image files, turn this feature on and enjoy the unparalleled editing power raw gives us. [MUSIC PLAYING]
With this tutorial, we will take a software independent look at some of the vital terminology that is required to build a solid foundation for learning some basics of editing images. The purpose of these standalone lessons is not to learn how to use any specific software, but rather to focus on learning fundamental terminology. It is recommended that you are familiar with all of the terminology that is discussed throughout these lessons before starting to follow along with any image editing tutorials.
