I'm getting ready to enter this into an art show at work and I really want to get rid of the blasted halo surrounding the train. If someone knows how, that'd be fantastic.
duplicate the file...isolate the train and select it.. increase the train size by10% and paste it into the original file this will cover up the halo.
..i would also clone the green tinge of the side window out.. it just dosent match
Ian, it's easier to prevent the halo rather than remove it.
The halo is the result of exaggerating what HDR programs do best, separate the tones.
It is best to go back to the originals, recombine them and then when you do the tonemapping, pull the sliders over until you start getting the halos, then pull them back.
Then process the image. The result won't be as dramatic but you can't have the tonal separation to that great an extent and not have halos. One or the other.
One trick I've used in similar situations is to clone from nearby using "darker color". That way it won't clone over the darker train body.
You might bring in one of the original pictures that had some details in those clouds and clone from that onto a separate layer and dial back on the opacity of that layer.
This picture _is_ worthy of entry into a contest. Wish you best.

I hope that helps.

Yup! That's right! Process for tones in the software that tone maps the interim HDR file - NORMALLY without the exaggerations and then for that freak-out "HD-Art" effect use Photoshop's "Shadows/Highlights" plugin which will allow you do to the same thing (even to a common single exposure JPEG) without the halos by setting the Radius appropriately.
Good tip Dan!
Done correctly though I have to add that the result will be just as dramatic - only without the halos.
