Here, I'll give you a step by step on how to do this, k?
I'm not sure how savvy you are with photoshop so I'll just throw it out there.
1) Photograph 3 raw's, one perfect exposure, one under, one over. I suggest a tripod, it'll make your life easier, I didn't have one for this and had to manually align them, even then it wasn't perfect.
2) Convert all three raw files into tiff's (for best quality)and open them in photomatix.
3) Photomatix: a)HDR>Generate HDR. b)select your three tiff files. c)"Attempt to calculate response curve" + "align LDR images" (sometimes used, sometimes not, depends) d) when it generates your HDR (High Dynamic Range) go to HDR>tone mapping. e)fiddle with these settings til you get what you like, press ok and save as a tiff again.
4) Open up your new HDR tiff into photoshop. I like to duplicate my image into a new layer so I always have an original available incase I should really screw something up.
5) Basically to get the color you see I used two "black and white adjustment layers" each with their own "tint". I started by doing the sky which looked awesome, but now the ground is red too. The nice thing about adjustment layers is they come with masks, so I told it not to show the ground, only the sky. With the second black and white layer I added a blue tint, copied the mask layer from the red tint and inverted it so now we have two mask layers that are opposite of each other.
6) From there I did radial blur with the center on the bus, again I used a mask layer to make sure there was some sharp detail on the bus, the ground around it, and a patch of sky above.
So that is pretty much basically it, if you don't get it all right away don't worry, I know for me the first time I encountered mask layers it was something different, but when you get it they become your best friends, believe me. So throw out your darkroom (sadly), filters are nice, but I didn't have the fortune of having my polarizer in yet, and if you like wide angles check out the Sigma 10-20mm, beautiful lens.
Can't be that hard, go get in one of them hollywood movies, there's enough of them there.... Hell we had one shooting in our park couple years ago, that was cool. I should point out my town is probably about 1/150th the size of yours (assuming, everything in california seems on a grand scale).
