Me and my friend Matteo we shot this little video to have a comparation with my Rollei 5S Diving and his GoPro Hero3 black. Not so big differences, despite the data rate of the Rolliei is about the half of the GoPro.
The Rollei 5S seems to better manage the colors.
shoot at 1280x720p - 50 fps
I have done some little color correction at the underwater shots only. Music: Champagne Dreamz (Shatterfreak's 0% Alcohol Remix) by Shatterfreak
