On real cameras and monitors

DSLRs often provide only a Histogram, although other features are becoming more common on some quite affordable monitors. Broadcast and news-gathering cameras have long included features such as zebra stripes, which draw a pattern over areas of the image above a selected luminance, which can provide a guide to exposure as well as a warning of ugly clipping. More advanced Waveform Monitors and Histograms may provide individual displays for red, green and blue channels, providing even more information and making certain grading operations easier. Ultimately, proper selection and use of test and measurement equipment may not only help to diagnose problems, but can make for easier, more consistent shooting and less reliance on grading to solve problems.
