I recently purchased a Hero 3 Silver. And I'm just wondering is there anything that we need to change on the GoPro if I want to shoot a sunset?

I took a series of shots (1.5 hrs worth) just before sunset, and towards the end of the timelapse, many of the pictures were overexposed, and it did not show the pretty red/orange colours of the sunset.

I know this had to do with the metering on the camera, however I'm not sure how I can change this on the Gopro. I'll upload what I shot the otherday later this evening. I'll have to resize the files, because I did a test conversion the other night and the end product came out to 1.1Gb

Is there a sunset mode or do I need to make those changes in post?
