Hi,
HDR means High Dynamic Range.The imaging sensor of a digital camera cannot see the world like the human eye and cannot record everything that our eyes actually see.If you shoot a high contrast scene with bright highlights and deep shadows something has to give.If you expose to retain highlight detail the shadows block up, conversely exposing to record shadow detail often leads to blown highlights that have absolutely no detail in them.To get around this you can shoot two or more exposures of the same image one containing detail in lets say the sky and one containing detail in the shadowy areas of the image.You can then blend both images in an image editor such as Adobe Photoshop ending up with something that contains detail in every part of the image.This is just a basic explanation,I hope it helps you,no doubt someone like andreyG will step in and enlighten you even more.

Regards, Les.

Hi Les - it is very close what you need for a beginning, one addition - steady tripod, and I mean steady. Solid. another 20 cents - PTGui is doing HDR as good as PS and less picky, + you can do hdr and panorama - both in one action in PTGui.
