HDR-High Dynamic Range:-
HDR Imaging is a technique of combining several differently exposed images to produce a single HDR image with 32bpc [a normal image is usually 8 bits per channel] image data embedded in it,giving you the ultimate controls on image manipulation.
Tip from paperbird: Shoot a set of the same image with different exposure settings in your camera. Shoot with a tripod to get the alignment right.Save it in camera RAW format.Open photoshop.Goto File>Automate>Merge to HDR.Browse and select the image sequence.Click OK to merge.Now you will have a 32bit image with all the exposure data in it.Work on it.Be prepared to be surprised!
PS: You need photoshop cs2 or above to access this feature.
