  • Live histograms are a function available when viewing electronic sensor-driven views...therefore they are not available when shooting with a viewfinder on a DSLR. In order to get a live histogram on a DSLR, you have to switch to the Live View mode - from there, if your camera is equipped with one, you should be able to cycle through the Display options and bring up a histogram.
