HDR at night is something I can't seem to do, it ends up looking awful

Enlighten me on how you did it please?
Hi KaPOWitsCHRIS
My workflow is as follows:
-This pictures is taken with 3 exposures +/-2EV, with AV program and a tripod.
-One of the pictures (20sec exposure) created the light-trails
-Pictures is taken in JPEG + RAW, I use RAW the few times I miss on the color balance, (or when Im not using the HDR function)
-After I have launched Photomatix I drag & drop the three selected exposures from the Bridge into the Photomatix icon on the toolbar. This starts the HDR process
-I use noise reduction on the darkest pictures
-When the image is processed, I don't use any of the presets templates
-I adjust Lightening Adjustments to between-10 and 0 (do not use any presets). With this slider you can reduce the halo by adjusting or increase the HDR-effect
-I put the White Point to about 4% and Black Point to about 0.33%
-After processing is complete I save the processed picture back to default location.
-Then I switch back to the Bridge and the Tone Mapped version ending up next to the three documents that have already been marked out.
-I select the generated image, together with the three originals and choose Tools -> Photoshop -> Load into Photoshop layers from Bridge
Doing this you end up having all 4 images as layers in the CS5 with the Tonemapped version at the top,.
-Remember to align layers if you have not used a tripod, Edit-> Auto align Layers
-Then start with masking the top image using Layer Mask to bring out interesting areas from the original picture into the Tonemapped version - and then Merge Layers. This is the main action to make the images the way I want (I enhance the colors of the 20 sec exposure version to bring out the light-trails)
-Finally, do I use Topaz Denoise to remove noise and Topaz Adjust to increase colors. You can also use Layer Mask if you just want to have the effect in only part of the picture.
This is my setting in Photomatix:

Otherwise there is a lot of good inspiration on
HDR Spotting - Gallery of HDR Photos and Community of HDR Photographers
Hope it was of some help and good luck
