Correct Histogram usage

I saw a post about this histogram. I haven't really used it much. I've used zebra, but not the histogram. What is the correct way to use it?

Try to set your aperture so the histogram is more or less centered. Do not lose any info off the right side. This would indicate the suject is overexposed while if it is off the left side it is underexposed. If you blow the highlights out you can't recover them in post very easily if at all. Sometimes you can recover some darker scenes but it is best to explose correctly when shooting. If your subject is very dark the histogram will be very tall on the left side. If this happens try opening the aperture or increasing the gain but be careful with using to much gain as it can make the image grainy.

As a still photographer, I was tickled to see the histogram display on the EX cameras. I use it in Photoshop and on my still camera as well. If you really want to find out a lot about this, you can perform a web search in that context (photography or Photoshop) since it's probably been covered a lot better there. Ron's suggestions were right-on, and as with anything it'd be good advice to make sure you get a little more detailed understanding of the tool in order to use it best.

Thanks, it was just one of those tools I've never used. There's always something to make my life easier, or more complicated. I've been using the zebra. I try to stay away from gain as much as possible, but sometimes I have to boost it to 6db for nighttime event shooting. Even at that, it's still pretty clean.
