Guys, it would be nice if you prepare quick RTMF for HDR (in English, please :))
There are cameras that can do real HDR, but very expensive.
You can bracket, which means a tripod, or you can develop differently from a RAW capture.
In my experience, a sensor can capture 7 stops, but a picture can only show 5 (stops may not be the right word, I mean whatever units Ansel Adams used).
Usually three exposures are made, one for highlights, one of mid-tones, and one for shadows.
Then they are blended into a single image (I tag mine 'fake HDR').
There's also Tone-mapping, which I haven't tried, but I almost never like the results.
