Great tips and advice. Time for me to buy a gopro
And i see i can even film underwater. was looking for that.
What software is best/easiest for editing?
For the Walkin tours i see Sao Paulo is not there. I can give you a route there. I walked there in many (dangerous/fun) parts. I made a video in Foz do Iguaçu waterfalls, also great sport for walking.
