Okay so I took these landscape photos, and while looking at them later I noticed the picture using flash discolored the horizon and the lake, and I didn't want to lose the color I saw.

I know this isn't grade A photography but I just want to see how my photoshopping skills are...

Notice the discoloration in Link2. Is there a way I can fix this on my camera without having to photoshop?

Anyways, here's the photoshopped version. I wanted to keep the grass in the photo while not having the orangey look in the sky.

Photoshop'd:

Also, I wanted to know if there was an easier way of doing this. I just paint brushed everything black on Link2 that I didn't want (Sky, Lake, spots in between trees) and used the Difference blend. Is there an easier way to do this or is this the correct procedure?

Please let me know!! I appreciate everyones help!
