Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
Digital photography offers us the ability to evaluate exposures instantly, so we can make on-the-spot adjustments to fix flash and lighting problems or improve our shots. Your camera’s LCD monitor is your best on-camera tool for evaluating your exposures and helping you make adjustments. Besides simple previews of your images, the LCD monitor can display useful numerical and graphical data about an image. What that data means, and how to use it are what we’ll show in this section. Accessing and presenting these types of data vary by manufacturer and often by camera model, so it’s a good idea to learn how to access these views on your digital camera now, so you can use them quickly when needed.
