Hello fellows.
Recently i saw some pretty nice images captured with a photographic technique called HDR (high dynamic range imaging”.
I’ve been looking for tutorials and tips to start practicing, but its hard to find something useful.
Can any one give me some help?

first you should mount your camera on a tripod and search for AEB auto exposure bracketing then assign 3 exposures after that you take 3 photos with the camera each at a different exposure use a remote control shutter release to get more stability then you can combine the 3 photos using photoshop or other programs such as photomatix

you also need to have a good noise reduction software such as noise ninja because when you over expose a photo you get a lot of noise

you also need to use curves in photoshop to make the colors pop

hope this helps

First you need a very stable frame, you need to take exactly the same frame several times. Depending on the subject and the lighting I usually take upwards of 5 frames at least 1-2ev apart, ensuring that all the detail that I want in the photo is correctly exposed in one of the frames.

From here I use the merge to HDR function in photoshop, alas I can't quite remember offhand where that is in the menus and I don't have photoshop on this machine.

I suggest you experiment with the settings until you get the feel of what they do, also you need to get an idea of which lighting conditions HDR will actually yield better results under, otherwise you are just wasting your own time.

Hope this helps,
Adam.

There are some great points here already. Let me just add another one.
From my experience, you achieve a lot better results by using a specialized software program called hdrsoft photomatix (hdrsoft.com). It is less than $100 I believe and well worth it if you want to improve your HDR shots. You can achieve very crunchy looking photos but also more natural looking ones, depending on your settings.
It takes a little time to get used to, but it is a lot of fun to play around with.
