I Begin by opening the raw file in Adobe Camera Raw. I mainly just adjust shadows, contrast, and saturation to my liking. Note that the color temperature is as low as it can go (2000K). I leave it in 16 bit if there's a chance I'll be printing it. For this demo, let's work with it in 8 bit to speed things along.

Here's the image as it appears opened in Photoshop. I currently use version CS2, but I'll be upgrading to CS4 soon.

Duplicate the image. (Image-Duplicate) Apply autolevels to one image. (Image-adjustments-autolevels).

On the second version, adjust the levels manually. Compare the two versions and choose the best to work on. I'm going to use the autolevels version.

Swap the red and blue channels. (Image-adjustments-Channel Mixer)

Add auto contrast. (Image-adjustments-auto contrast)

Add autocolor to image. (Image-adjustments-auto color)

Add saturation to the yellow channel. (Image-adjustments-hue/saturation)

Apply curve to image to your liking. (Image-adjustments-curves)

Tone down the blues in the image. (Image-adjustments-hue/saturation)
We could stop here and call it done, or ...

Select one of the palm trees at the bottom of the image.

Make the yellow channel of the selection a different color.

Select a different tree. make it another different color.

Here's the final image, after cloning out a dust spot between the yellow and red palms.
