    Wow, these look awesome, so you used an HDR camera?

    Thanks. As far as I know there is no HDR camera. It would be really convenient to have that, but until the technology gets there, it is a bit of a process. You need to take multiple shots of the same thing in different exposures. Usually it's something like -4, -2, 0, 2, 4. Then you need to load all of them into a program that blends them into an HDR file. Then in order to get it to display on a regular computer monitor you have to tone map it which compresses the file into an LDR file. Then you can still do a little post processing if necessary. *tries to stop hyperventilating*

    HDR is relatively new. It's also a lot of work to do, and it only makes a big difference in very specific situations. It was originally intended to prevent the clipping of lights and darks in high contrast scenery. The second to last photo is just a single exposure I took on a whim. I didn't even bother setting up the tripod. It still turned out alright, but there are blown out highlights.

    @David Wood & others,
    HDR is a necessary evil.
    Our eyes can see contrast ratio's far beyond what any camera,display or printing paper can realize.
    That's why it is often called "fake HDR".
    I'll not explain how it's done since that's already done in earlier post.
    In analog black&white photography it already existed.
    I did it myself:When you wanted to print an enlargement you cut "masks" out of cardboard.
    Then when you exposed the paper under the enlarger these masks were used to cut of exposure
    of shadows and/or "burn in" highlights.
    The masks were attached to tin steel wire and you had to move them to avoid sharp contours.
    Gerard.
