Here's some HDR'd photography of rural Russia from Englishrussia.com. Thought I'd pass it along if anyone needs a breath of inspiration as they work on their landscapes!

Best to use 5+ images, the more you have with finer stop difference the more you can modify the merge to keep all the detail you saw. The first photo in that series doesnt look anything close to natural. Like I say though, plenty of the others are very nice.
so what, can you take any image you have, alter the brightnes in photoshop and create your own HDR image or do you really have to take each single picture manually?
HDR takes all that tedious zoomed in work out. I still advise using as many exposures as you can - there is nothing to be lost in this process unless you've got fast moving clouds in your scene and can't afford to take too long snapping. The 3 exposure approach is easy as any camera can be bracketed so you can potentially do the scene in a very short time. If its a still day, or probably more usefully if you're shooting an interior - take 5, 7, 9 exposures. It all adds up to a richer scene and if it looks better with 3, just don't include the intermediate steps in the merge.
Some (the better ones ) cameras can do that automatically, you basically tell the camera make x shots with these exposures.
Then you throw the images into a software to create a HDR image. Photoshop has this function since CS2 iirc, but it really sucks.
90% of the time you get an hdr image which looks really ****ty, the reason is simple: your monitor can't handle it
The most common thing is using tone mapping or a detail enhancer, depending on the image, one of them will do the job.
You are right, it does not hurt to take more images, but most of the time it isn't necessary.
Photoshop CS3 extended's HDR function sucks and HDR images looks ****ty? Never had a problem with it . All of the other HDR functions are really cool too. 3 exposures is ok but a pic with a lot of tonal values 5 or 6 is better. All depends on what you want to do with it (size, format and media of pic) and how detailed it has to be.Then you throw the images into a software to create a HDR image.

One thing those pics DO demonstrate IMO is that, if you can, you should use a 4096 x1024 skybox texture to do justice to those banks of cumulus clouds stretching off into infinity.
