I have been playing around with some HDR images..i noticed there are a couple of different techniques that some photogs do, or at least what i have been doing myself.
For instance you have the "in camera" HDR method, to where it snaps either 2 or 3 images and combines them in camera.
then you have the bracketing method, to where you take 3 exposures with options of -3/+3 and so on and able to shoot RAW.
Then you have the option in lightroom to duplicate said RAW images, increase or decrease their exposures then combine in whatever PP software you choose, which i tend to use photoshop.
the easiest method for me has been the lightroom method shooting RAW, as with bracketing you need to have a REAL steady hand or a tripod available, and the "in camera" option seems limited to me, as at times i like to set my exposures a bit differently. But if you prefer a different method or any of the above mentioned, i would like to know why..curious to know if one is in fact better over the other.
I always use the bracketing method. It's just a lot easier and gives you more data to work with. I've tried the other methods but they're more work and just not as good. Having said that, I'm an HDR newbie and not an expert.
The one problem with taking one single exposure and increasing and reducing the exposure levels in post is that most HDR programs are written to take into consideration registration differences between images. The programs are generally very good now about lining up small differences in position of one image to another. It is my understanding that without these variations the programs actually produce less than optimal results.

Option #3 where one creates several images from one raw image is not truely an HDR image since there is no real "high dynamic range". This is really a Pseudo HDR which creates an effect that looks like HDR. True High Dynamic Range images must include information above and below the mean exposure to increase the "dynamic range". The dynamic range of an image is not expanded when one only uses the data included in a single raw data file.
The main reason to use multiple images is your eye can see twice as many stops of light as best camera ever made. If you shoot raw images you get more than the JPG normal 8 bits of color. Even the D3100 can capture 10 bits in raw mode and others even more. The combination of this extra data across several exposures is the beauty of HDR. There isn't just one way to do it and they all have a different look. Blending them together is like baking a cake only better. Finding the way you really like has a lot to love. The Nikon in-camera HDR modes are not bad and a good example but real HDR goes a WHOLE lot farther. You just need to get your hands into the dough to cook it up proper. It's the laying of hands to the image that makes it art! Digital is still an art!
