please can someone in a simple manner explain hdr and how to do it . is it something to do with taking thre exact images? :D
AndyLParticipantTake a number of shots of the same scene. If you have very bright areas ie clouds lit by the sun, to expose the rest of the scene correctly, these will be washed out and white with no detail. To expose the bright areas correctly, the shadows will be black with no detail.
So take multiple (usually 3+) exposures of the same shot, 1 underexposed, 1 properly exposed, 1 overexposed then combine the nicely exposed bits of each one into one final image, and bobs yer uncle. Software is handy for the last bit…
aoluainParticipantHDR stands for High Dynamic Range.
The resulting image is very much how the human eye sees images.
as andy said you are blending maybe a bright sky and the proper light
and shade of a foreground image to get a more “realistic” result.It is a very different form of photography but I think is only works well
for certain subjects.Yes you will need HDR software to convert and blend the images.
You will need a tripod and maybe a remote shutter release because you are going to blend
3+ images together.
If the images are not exactly aligned with each other you will get ghosting in the
final image.Good Luck

stasberMemberHDR software (some is free – just do a search for HDR software) will help you align the three images, however you’ll help yourself by starting off with three or more identical images, hence the advice of tripod and remote release is good.
There seem to be two camps of HDR users, one that like to make images that are distinctively “HDR’d” and look unnatural but can be cool or uncool depending on your personal taste, and the other which use HDR to make brilliantly lit and balanced images, close to what the eye would perceive (I’m in the latter camp of persuasion).
Either way it’s mostly up to you to install some software and find your own way with it, as options are many. I’ve tried it a bit and can say it takes some fiddling about to get some decent results.
Here’s a couple of Flickr groups for HDR:

BriankParticipantHello Scottie,
quickest way to try this would be to take one photo in raw mode. In photoshop make one normal exposure then one +1 and one -1 exposure in the raw processing screen. Then open all three in either photomatrix software or photoshop. Do a blend and use the tone mapping tool to fix the blend. This saves you having to worry about tripods etc. As you learn the technique and want better quality then use tripods and aeb modes.hopes this helps.
