HD eerrrR

So I have seen a few HDR blips and wanted to do it my self. Took the camera out to the hills to get some pictures along with my gorilla pod. I have read up a little bit so took one shot under exposed and one over and then a couple of colour.

20 minutes in Photoshops HDR automation process and this is the end result. I think I have got something wrong as the colours have gone very wacky. I had a look around to see what it might have been on forums but no luck, if anyone knows what I have done or what I can do next time to make the colours right it would be appreciated.
