NOTE : this tutorial is seriously not meant for those who believe that photography should not involve any post processing.its also not for those who dont believe in HDRs or for those who think HDR is cheap.
this tutorial is a rip from my post at photography thread.meant for those who want to involve themselves in this particular field.
NOTE 2 :HDR is an art just like photography.there are two aspects in it.realistic and artistic.i am bent towards the artistic side.which involve painting like effects.so if u do like those,then imply it.otherwise the link carries some interesting stuff about realistic ones. its art.not technique.
like they say,post processing is art.not a technique.through that technique u create art.
for a serious detailed HDR tutorial..with in depth PS technique..visit here.
http://stuckincustoms.com/2006/06/06/548/ u will love it.
mine is a basic starter one.

taken straight from wikipedia...explanation of term HDR.
In image processing, computer graphics, and photography, high dynamic range imaging (HDRI) is a set of techniques that allows a greater dynamic range of exposures (the range of values between light and dark areas) than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.
High Dynamic Range Imaging was originally developed in the 1930s and 1940s by Charles Wyckoff. Wyckoff's detailed pictures of nuclear explosions appeared on the cover of Life magazine in the mid 1940s. The process of tone mapping together with bracketed exposures of normal digital images, giving the end result a high, often exaggerated dynamic range, was first reported in 1993[1], and resulted in a mathematical theory of differently exposed pictures of the same subject matter that was published in 1995[2]. In 1997 this technique of combining several differently exposed images to produce a single HDR image was presented to the computer graphics community by Paul Debevec.
This method was developed to produce a high dynamic range image from a set of photographs taken with a range of exposures. With the rising popularity of digital cameras and easy-to-use desktop software, the term HDR is now popularly used[3] to refer to this process. This composite technique is different from (and may be of lesser or greater quality than) the production of an image from a single exposure of a sensor that has a native high dynamic range. Tone mapping is also used to display HDR images on devices with a low native dynamic range, such as a computer screen.
HDR stands for high dynamic range.you must be knowing that a normal photo has a certain level of shadows and highlights.through HDR you add the details of the shadows and highlights +-EV.you will find def of HDR on wiki and such so do check it out.your +-EV may start from a mere 1/3 and go upto say 3.

speed is not the only thing that matters.
In HDR unlike normal shots your main factor is not the subject per se but the light that is actually lighting the subject.
.and then you have a total 360degrees of light available for you.that makes 360 shots supported by infinite angles and perspectives at which you can shoot a subject.
say for example..keep an apple in a softbox.place one lamp.start at 0 degrees and end at 360 degrees.and keep on changing the angle.you will find out that from some angles the apple looks better than normal light,in some the apple doesnt look like an apple,in some the apple may look that is impossible to potray.
convert that example into say a car standing in a parking lot and sun rays..falling on it.now you have almost 180degrees of light..considering its a sunny cloudless sky..plus your infinite angles.
so you get how light plays a vital part.
again clouds act as natural diffusers of sun light.as they diffuse they provide smooth lighting to the subject as well as nice atmosphere.combine this with HDR and you get photos that are unique.
example.
if you consider the TATA example look how the light is falling on the indica.part of that light is played by the clouds.they are actually targeting the light to the car while the clouds below is dark.so sort of concentration of light.
but again i am not saying that you cant turn your home theatre photo you took into a HDR.you can ofcourse.or of the window.but an HDR looks beautiful if it has a ray of colors.
now i am coming to the actual HDR shooting.all you need is a camera a tripod and a nice lens.(since you are a DSLR user)preferably a wide angle.since then you can cover more landscape.
shoot using your AEB function of your camera..so find out from your manual and use it.keep the format on RAW.keep your AEB option at +-2EV.this will give you enough details at both the extremes.you can also do a 9 exposure by incrementing your values from 1/3 2/3 + - and so on.first its better you do a 3 exposure.
thats the easy part.now comes the processing part.and many will say use photomatix.i personally use DYNAMIC photo HDR from mediachance.ofcourse its not licenced.you will get it if you know where to search for it.
now the actual tutorial..purposely posting 1024*768 since then the text can be read clearly.

after this u can further process in PS.
sunny can guide on the realistic one tut.involving photomatix.
and using the same technique a same subject 30 HDR experiment.
