I like both images, but am more drawn to the color image. The highly saturated colors remind me of the feel I used to get with Velvia50. I assume this was a single image reprocessed with several raw settings and then recombined? Maybe you could post the original as Aperture would see it to show the difference.
Cheers,

Thanks guys for the comments.
Here are the original images:


Jeff couldn't you get the same effect with a reverse Grad?
I'm sure there are a lot of ways to do this including Photoshop's HDR, but I really like the level of control and the options available in Photomatrix
I am for the B&W myself - but again I have a bias that way.
Tempting me to have a go at this HDR thing myself.
Any suggested place to start reading about it Jeff ?

If you go to Photomatrix's site there are some good resources there, and I really like a book called Complete Guide to High Dynamic Range Digital Photography by Ferrell McCollough
Just curious ... is the dot on the middle of the horizon to the right of the sun a ship?
The dot on the horizon is a buoy.
This image took a lot of work and I can explain it for those who have an interest.
I was bobbing about on the jetski at the inlet trying to do 5fps captures bracketed 1 stop with the hope of catching the sunrise and doing HDR processing when suddenly the Dolphins showed up. So I was shooting at 5fps bracketed and of course now I had moving subjects as well, and as it turned out the dolphin image I liked was well exposed for the foreground but the sky was blown out being two stops overexposed as you can see in the above image.
So what I landed up doing was combining the well exposed sky image with the dolphin shot, correcting the malalignment due to the bobbing jetski. I then used a gradient fill mask to blend them at the horizon, correcting the tilted horizon and making some curve adjustments etc, Then loaded this as a single image HDR into Photomatrix and used the Detail Enhancement Tone Mapping mode, and played with the sliders a little.
I really like the image and think it's worth working on a little more before printing. To address the issues George (ScorpioFish) mentioned, I think I will combine the pre-photomatrix image with the post and blend and mask to taste, also want to tidy up the horizon blended area a little.
