Starting Points and a Finishing Tip for HDR Images are in important think to create better result for HDR image, and Both HDR Soft's Photomatix and Nik Software's HDR Efex Pro are great collaboration two HDR software for stunning into hdr photo. see image below
When using Photomatix, adjusting the White Point and Black Point sliders is better to start . First, move the sliders all the way to the left. Then, move each slider to the right until it lose either Highlights (White Point slider) or Shadow detail (Black Point slider). Then, move each slider back to the left just a bit.
The goal is not to lose Highlight or Shadow detail (read : Correcting Exposure with the Shadows and Highlights Tool) - which is the goal of HDR photography.
When using Nik Software's HDR Efex Pro, first select a preset. Then, adjust the Tone Compression slider. It's amazing what your eyes can catch with that!
As a finishing tip... you'll find that your HDR image will probably need a bit of sharpening. I do that in Photoshop, using: Filter > Convert for Smart Filter > Unsharp Mask. Using this technique, you can sharpen selectively.
Whatever technique you use, sharpen selectively. For example, in the image below, there is no need to sharpen the sky.
