Critiques:
-I know it's hard because you don't want to be shooting into the sun, but watch you shadow. Unless you're trying to make it the subject of the picture, try to keep it out. (first pic)
-None looked too bad, but especially with less light keep the camera as still as possible or the pics will end up kinda blurry. (some of the fly fishing ones)
-Gopros will overexpose really badly if you're in shadows shooting at something brighter. I've noticed that it corrects this in the first couple seconds of video, but not so much for pictures, so just watch that. (third to last one)
Everything else look great, i really liked the one with the fireworks and the one of the dog in the river. Remember, the gopro was built to be sturdy and versatile for shooting action, so try use it as such whenever you can. Taking it in the river was a great example of this. Just use it in ways people would be hesitant to use other cameras.
I used my gopro a lot this summer, and i have some pretty cool pictures from WY and the Badlands National Park I'll put up later.
