The above image is the original Raw capture straight out the camera, with no work done on it. I could have done a better job regarding exposure but I like the end result after working on it. Thats an advantage of shooting in Raw, you have a lot more to work with, a 12bit or more file compared to approx 8bit jpeg file.
This is after working on the image using adobe lightroom, I mainly got lightroom for processing Raw files, but its a great programe, I prefer using it to photoshop or paint shop pro (and I prefer paint shop pro to photoshop) I think photoshop is just to complicated. Lightroom is a lot more user freindly, and in my opinion better at doing what it does, it seems to be more geared/specific for use by photographers. I used a variety of tools in the develop tab to alter the exposure, contrast, brightness and clarity in certain areas of the image. I also used the luminance and saturation tabs in the colors to enhance the blue and clouds in the sky, giving the same effect as a polarizer filter. Also used the green and yellow saturation to enhance the color in the tree. Taken with my Canon 30D, Raw capture, iso 100, at f11.
