What do gopro photography 4K30 and 2.7K50 fps mean? I want to know if gopro hero 3 white is enough if it is just for selfies.

Self-portrait is enough, but it is a great waste!

GoPro is mainly aimed at high-speed photography of sports. For example, you are riding a mountain bike and walking at high speed in the mountains. The high frame rate (fps) shooting function provided by GoPro can record every moment in high-speed motion very well, ensure the clear image, and provide very good video material for the later slow-motion production.

Fps is the abbreviation of Frame per Second, indicating how many photos are taken per second. 50fps means that the video is shot 50 times per second.

About resolution:

1080p =1920x1080 pixels (16:9)

720p = 1280x720 pixels (16:9)

1440p =1920x1440 pixels (4:3)- Hero 3: Black version only.

4K= 3840x2 160 pixels (16:9)- Hero 3: Black version only.

4K Cin = 4096x2 160 pixels (17:9)- Hero 3: Black version only.

2.7K= 27 16x 1524 pixels (16:9)- Hero 3: Black version only.

2.7kcin = 2716x1440 pixels (17:9)- Hero 3: Black version only.

960p = 1280x960 pixels (4:3)

WVGA = 848x480 pixels (16:9)

In addition, regarding the shooting format, you asked about 4K30 2.7k50:

Each camera has its own maximum limit for processing data. The higher the picture resolution, the greater the amount of data per frame, and the heavier the processing load of the camera, resulting in fewer frames per second.

4K 30fps means shooting 30 frames per second when the resolution of the shot picture is 4K, that is, 3840x2 160 pixels.

2.7K 50fps means that when the resolution of the shot picture is 2.7K, that is, 27 16x 1524 pixels, 50 frames are shot every second.

Many instructions use the following methods to express the relationship between frame rate and resolution:

4K 30 frames per second

50fps@27 16x 1524

On the question of whether selfies are enough:

As a still photo, there is no such thing as fps, because you don't need to take many photos every second, it is always 1. At this time, only the reference resolution is enough. As a still photo, 4K is not very demanding, especially for commercial photography, but it is generally sufficient for non-commercial use of self-portraits.
