GoPro is amazing for outdoor video recordings as it’s build up is robust body is made to take all the beatings which unfortunately occurs on the course of adventure.
There’s a reason why a photographer who goes for post processing of pictures shouldn’t buy GoPro.
Few of the models like GoPro Hero 4 silver does not snaps pictures in RAW format due to which the picture tend to pixelate while post processing.
Therefore be selective while purchasing GoPro.
A better deal could be GoPro Hero 5 , Hero 6 or Hero 7 which takes snaps in RAW format.
