The GoPro is quickly becoming my favorite camera to take hiking. It is lightweight and unobtrusive, compared to even a small DSLR or compact. The battery lasts long enough, and with a case on it it can be waterproof. I actually carry a pair of them, one with a screen and a polarizing filter and an LCD for landscape photography, and one just for pointing and shooting with no filter or LCD.
One issue I have with the LCD is I can’t see it at all in the sun. Its not particularly high brightness, resolution, or contrast, and if I can’t see it, it is just burning battery. Not being able to see it also makes it impossible to properly adjust the polarizing filter, which means I end up with blurry, flat photos sometimes.
To resolve this problem, I printed a shroud to go around the back of the camera. Friction and potentially rubber bands can be used to hold the camera in place. A lens and an eyeshield make it comfortable to hold up to the eye and see what you are shooting.
It looks like it works so far. I am excited to give it a test run in the real outdoors, although it may need a few more features before then- like something to hold in the camera, and eyelets for a strap.
