Hi Dynamic Range Images (HDR)

(Examples of HDR Images)


We had a brief discussion between lectures yesterday about High Dynamic Range images (HDR).   I use this technique more and more in my photography but in a way that I think helps the creative process rather than over-blows it.  The technique is very seductive and it is very easy to apply the tone mapping in such a way as to make the whole thing look artificial more like a neon painting than an image.   However, if used in amore subtle way it can greatly enhance an image.  The technique I use involves creating virtual copies of the original image and using these to increase and decrease the exposure.   I have found this to be more successful than the more traditional method of capturing 3 bracketed images and then blending them together.   One final thought about HDR that I still have to clarify in my mind.  

It certainly helps me with my photography but I am also aware that this is not to everyone's taste and that is a good thing.  If it wasn't then we would not have the freedom's that we currently enjoy.
