Nope, no polarizer. This was shot with my Olympus XA, which has no place to put filters. This is straight from the camera to film, and then I did my best to get the scanned image to look as good as the original.

Nice job on the water, the contrast was pretty high in my shot like this one. Were you using a polarizer for this shot? The rainbow was quite brilliant, but if you were using a polarizer you could make it either optimal or nearly disappear.
