People love taking pictures, as evidenced by the constantly evolving world of cameras and the corresponding demand for better and better versions of them.

Two of the more prominent brands now in the camera business are GoPro and Graava, and each one's latest offerings provide features that may lead a particular person to choose one over the other.

Starting off with the GoPro HERO4 Black, which is arguably the more well-known of the two cameras, what is probably most attention-grabbing about this one is its ability to capture footage in 4K, according to Digital Trends. The GoPro HERO4 Black's ability to capture high quality images and footage is good enough to that point that filmmakers willingly opt to use it for their projects.

While 4K footage might not necessarily be needed for simply shooting one's own exercise routine, the GoPro HERO4 has not sacrificed any of its ability to capture high quality action footage even with the more advanced features. The camera is even being used to film professional sporting events.

When it comes to sheer image and video quality, it's tough to argue any action camera can do better than the GoPro HERO4 Black, but Graava aims to do better in a different department.

According to Business Insider, Graava's main selling point is simple, and it is the fact that this action camera can actually auto-edit the footage that people capture.

Graava will automatically edit the footage it records so as to provide users with only the moments they actually want to see. As for how the camera does this, it makes use of different kinds of sensors such as visual, heart monitors, and even things such as Global Positioning System (GPS) and accelerometer to at least attempt to see how people react to what is being recorded and go from there.

If Graava's auto-edit feature really does bring out the best in self-recorded footage, then it might just be capable of putting up a fight against the GoPro HERO4 Black.
