Here's a little "behind the scenes." I extracted these photos from the one picture I took shooting in RAW. The RAW format file has the entire range from light to dark. From this you can extract as many pictures as you want. "Reshooting" the shot by adjusting the settings and saving out that particular image. Change the exposure, temperature, etc. to get a quicker shot like A or a longer shot like D. Most cameras take in all this info but based on the camera's settings it only stores a small portion of what it sees... like, say, shot B. The rest of the information is dumped and lost as the photo is saved as the JPG on your memory card.
Images have a standardized "range" of 256 shades of grey in each channel of RGB (Red Green Blue), together producing millions of beautiful colors. High Dynamic "Range" refers to the much greater range beyond 256 that the RAW contains. However, because 256 is the standardized number, in order to be displayed on the computer monitor, the web, or in a program, even my HDR image has to follow the rules, and only be 256 shades in each channel. This requires some adjustment, and indeed ALLOWS for some reworking of the image. I pick and choose what parts I want, and what parts I don't want. I dont want dark buildings, I like seeing the details. I like seeing the gradient of color in the sky instead of being blown out. These are some of the decisions I get to make when producing a more dynamically spliced together image using this great range of information stored in the RAW file.
So the word "dynamic" refers to multiple things (to me anyway). It refers to the way programs can dynamically access and reshoot your shot. And it also refers to how the information stored is used by the photographer to dynamically build a nonlinear image.
Philosophically, this is really no different than how early film photographers spliced together, edited, cleaned-up, and reshot photos in their darkrooms. Computers and digital photography have just enabled everyone to go that much further in having fun with their hobbies. This is why you see Mr. PlumpChump playing around and experimenting with it.
It certainly gives me a strong respect for how amazing our eyes are. They are able to see a range FAR broader than the meager 256 shades.
Hopefully the 256 standard will be increased to 512 or 1024 someday to closer mimic what we really see. =)
