    was in virginia and DC, finaly got time to edit pics. i did multiexposure shots (some 5 steps and some 3 step). here are results. used photomatics and its really easy to use unlike doing it in photoshop. each pic took less then 3 mins

    learned that doing HDR of landscapes doesnt come out very sharp if conditions are windy couse trees look blurred and such

    Gorgeous pics! To stop the blurring in the trees, increase your shutter speed. I set mine on 1/500 and can stop running water! Very cool.

    sure.

    for HDR you need either 16bit Tiff or Raw file or 3 step exposure shot of same image.
    for example taking normal picture, shutter speed would be 1/250 sec for example. this will give you normal image. then you take overexposed shot of same picture (this will be used for shadows or under exposed areas in first normal pic you taken). then you take under exposed shot which will be used for overexposed areas of first normal picture.
    then this software (photomatics or photoshop (photoshop is harder to use for this)), combines 3 pictures(sometimes 5, sometimes as much as 21 pictures), i only do 3 or 5 couse camera has setting for this.


    in software it gives you controls to lighten up dark areas and darken light areas so image looks like once above. (ill try to post 3 images used to creat HDR image) and it uses those 3 or 5 exposures color depth info to creat one High Dinamic Rance image. some ppl dont like it couse its not "real" picture but i like it couse it boots colors and give nice picture.

    so when you mentioned above that increase shutter speed, it would not work in this situation couse sometimes shutter speeds need to be pretty slow to capture dark areas.
    im sure you can find better info online but thats my version :)

    my dads camera does it all in camera with pretty good results but it doesnt have as much controls as photomatics or photoshop

    Very cool shots OP. :thumb:

    I've messed with HDR a bit and did a brief tutorial on another forum site I belong to. This tutorial allows the use of a single RAW file and the bumping of exposure in software to do the same thing Misha did in the camera. Misha, you might try this for the shots that have blur issues, just pick the best single shot you want to work from. Anyway, hope someone finds it useful.

    OK - This assumes an environment including a Nikon camera for the photos, and a PC for editing... I use a Nikon D40, Nikon's ViewNX software for manipulating image exposure and PhotomatixPro to build the tone-mapped image. ViewNX comes standard with Nikon DSLR's, Photomatix is available here:
    http://www.hdrsoft.com/

    To build a tone-mapped HDR file you need to start with three versions of the same original file, each with a different exposure (2-stop increments.)

    From Photomatix's tutorial:
    "If your camera offers Auto-Exposure Bracketing (AEB), select the Continuous Shooting mode, make sure the camera is set to Aperture Priority, and select an exposure increment of +/-2. The camera will automatically vary the shutter speed each time the shutter button is pressed, taking several exposures spaced by two-stop increments."

    Alternatively (and this is what I do,) you can start with a RAW image file and create two additional copies with modified exposures, then import these into Photomatix. For Nikon these are 'NEF' type files and ViewNX can open and manipulate these to create the modified copies. I'm not sure what the equivalent Canon RAW files are called, nor which programs can modify exposure for those files, maybe someone can add that here (or I can figure it out if need be.) Same goes for the Mac users if need be.

    So, open the NEF file in ViewNX. Under the File Menu choose "Convert Files" and save a modified version to a working folder. Choose JPEG for the new file type and change the dimensions if you like with the "Long Edge" being 800-1024 pixels if you're going to publish on the web in a forum like this. For email or to make a poster or something you may want to leave the dimensions unchanged. Anyway, the first saved copy will be your base file. Now do the same thing twice more, but modify the Exposure each time by selecting the "Quick Adjustment" tab and using the Exposure Comp. slider.... -2.0 for file #2, and +2.0 for file #3. Save these in the same working folder as the first file.

    Here's an example of ViewNX with a NEF open and Exposure adjusted to -2.0.

    _____________________
    Here's three example files after the procedure above:

    [​IMG]
    _____________________
    Open Photomatix, drag n' drop the three files onto the interface. Confirm to "Generate an HDR image." Select all three files and click "OK." Specify the E.V. spacing as "2." The next page will select HDR Options, I leave these as-is except I select "Align source images" and "By correcting horiz. and vert. shifts." I leave everything else un-checked (default) except for "Take tone curve of color profile." Hit "OK" and click "Tone Mapping."

    The image will open in the interface, select "1" for Ratio to Original. You get a default tone-mapped file. Example:

    _____________________
    From here it's just a matter of tweaking the settings on the "Details Enhancer" tab to create the desired effect. Here's 2 minutes of tweaks:

    [​IMG]
    _____________________
    Once the effect is as desired click "Process..." and "File" | "Save As..." to save the new file.

    One more version. This time I used 5 versions of the original, in 1-stop increments. I exaggerated the effect further as well.

    Here are some more shots, first 4 I found elsewhere and they inspired me to check out HDR, last two are mine, mild HDR manipulation.

    yeah photomatics can do HDR from single file as well but im sure its not as good as HDR from 5 exposure shots or even 3 if they spaced apart good amount
