In 2010, I finally purchased a camera that had built-in 'RAW' (14 bit dynamic range on Canon T1i) capabilities in addition to the standard 'JPG/JPEG' (8 bit dynamic range) image format.  This provided an entrance for 'HDR' ('high dynamic range') photography.  I have just barely started to scratch the surface, but here are a few samples that I have created so far...

This first one is a 'pseudo-HDR', since it is artifically created from a single RAW image.  Here is the original in JPG format (click on image for full-size):

Here is the pseudo-HDR created from that single RAW image into 'enfused' ('tone mapped') style, converted to JPG format (click on image for full-size).  I used the script by 'sillyxone' to do this:

Here is the same image in 'mantiuk06' style.  I used the script by 'Edu Perez' to do this:

Here is the same image in 'fattal02' style.  I also used the script by 'Edu Perez' to do this:

The 'right' way to do HDR photography is to use multiple 'bracketed' exposures and combine them into one 'HDR' image.
