Real-world histograms

Earlier we looked at a live histogram display from a camera. That's where I see a…histogram superimposed over my scene on my LCD screen on the back of my camera.…A live histogram can be useful.…The problem with it is, as you move the camera around, the histogram is…jumping all around.…I find it pretty complicated.…I prefer to work by shooting an image and then reviewing the image and turning…on a histogram display on the back of my camera.…Here is a kind of a typical information view in playback mode on a camera, and…as you can see, I have got a histogram here.…

If you go into playback mode on your camera, and you don't see a histogram,…you will just see a big full-screen image, maybe with some of this exposure data or not,…it doesn't mean your camera can't generate a histogram.…It may just mean that you have to cycle through a couple of different screens of…information before you get to something like this.…And here you can see exactly what we saw before.…This is a typical histogram.…I have got black over here, white over here, and so what I am seeing from this…
