HDR Processing First Steps: In Photomatix, set the White Point and Black Point. In HDR Efex Pro, set the Tone Compressor.
In Nik Software's HDR Efex Pro, you can quickly and easily compress the brightness range of a scene by adjusting the Tone Compressor slider. (After that, use Control Points to fine-tune your image even more!
If you still lose highlights, and if shadows are still blocked up, you mostly likely did not take enough exposures to capture the entire dynamic range of the scene.
