The intent of this group is to feature pictures surrounding HDR specific technology and tools such as Photomatix (or the plug-in for photoshop) and FDRTools used for creating or developing high bit HDR images.
What is HDR?
It's basically a way to 'digitally develop' your photos using tonal information contained in multiple exposures of the same shot. Say you exposure bracket the same shot. You can merge all three files into one 32 bit file and use the data contained in the images to create one master output preserving accurate details from all exposures.
