Although I believe in taking a photo right the first time, it's hard not to use Photoshop these days, it helps with production & can create some very interesting techniques that go along with film. A popular technique these days floating around is the HDR, but with some Photoshop magic one can recreate this look. I took an old negative, scanned it and voila... three different versions...
HDR affect, without a negative and with a negative (or image)
Here is the original photo, taken somewhere in Malibu area, near Struass Park in California.
