Thanks Adam.
My post processing is usually fairly simple.
1. open RAW image in CS3.
2. adjust white balance if needed.
3. adjust exposure, fill light and blacks (I can't yet afford good GND filters yet

and I don't want to get the cokin ones which I have been told are a waste of money) so basically I'm replicating this but it does tend to degrade the images if pushed to far.
3. contrast adjustments if needed then a little saturation and viabrance, if the colours don't seem right to me I may adjust the individual colour channels a little to get the right colours but this is very rare.
4. save as TIFF file with settings to a 16bit image, straighten horizon remove dust spots etc.
5. **stupid me forgot a very important step

sharpening I first change the mode to LAB and select the lightness channel then use an unsharp mask then convert back to RGB.
6. I usually run the images through neat image too to remove noise and then resize and I'm done.
I have an old CPL which has heaps of spots on it that I have to clone out at the moment as I'm to lazy and frugal to replace it

and for some reason I have been getting a lot more CA than normal which I have to manually remove, I'm starting to wondering if the abuse the camera gets is starting to wear it down

I think the blue on the rocks of #3 is just the deep blue sky above reflected off the wet rocks as I think I had the CPL turned so it was giving no polarising effect, but I may be wrong there.
There were several reasons why I used the photo I did in the comp, mainly because I didn't think that I'd have the others done in time and the long exposure ones need some noise reduction which strips the EXIF data, also I sort of feel a bit weird entering the long exposure ones as it doesn't really seem right to enter them.
Hope that helps explain my post processing techniques

if anyone has any other questions feel free to ask I'm more than happy to help.
