I changed my white balance a tad, cropped a bit, resized, added a border.
Not much in terms of color in photoshop, not really sure how to do that kinda stuff yet =) Just the basics!
I was using a plethora of filters to get these photos just right. Spent a good amount of time setting up for each.
I used a Graduated ND filter for most of the shots with the skies, (cokin p with hitech gnd soft edges), solid ND filters to tone down the ridiculously harsh light, circular polarizers to REALLY bring out the saturation for colors, and I had a handful of warming filters and color filters that I can't even keep track of. Lots of vignetting though from stacking and what not, but in the end I actually get some sweet saturation exactly the way I want.
Sometimes I want to just say screw filters, and just do the rest in photoshop =P But heck, it's fun sometimes to just shoot it just right, or pretty close it it at first. It's half the fun of photography... the other half is the journey
EDIT: Forgot to mention, I use a Nikon F2a, Nikon D80, and a Sony point and shoot S86 or something =P
