The time for which the shutter of a camera remains open is called its shutter speed. When the shutter remains open, it allows light to enter through the camera. Light is received by the sensors, which then transmit it for processing and production of the image.
If you intend to click pictures with your GoPro, the Protune feature allows you to juggle between fast and slow shutter speeds. You can use a fast shutter speed when clicking pictures of high-speed action in well-lit outdoor conditions.
Moreover, if you want to click pictures in a backdrop like the night sky, for instance, you can switch to slower shutter speeds.
The Protune feature also allows you to alter shutter speeds for video recording. Here, the shutter speed is a multiple of the Frame Rate (FPS). It means that if you shoot at 60 FPS, you get to choose shutter speeds like 1/120, which are multiples of 60.
The EV Comp setting or the exposure compensation decides the brightness in the final image. The exposure compensation settings in the Protune mode ranges from -2 to +2. If you wish to record videos or capture photos with more brightness, you should raise the exposure compensation towards the positive value. Conversely, if you need less brightness, you should go from -0.5 to - 2. The ideal exposure is at the 0 mark.
White Balance setting in the Protune mode helps remove unwanted casts. Moreover, it aims to present any white-colored object in its innate white color and preserve all other colors in the frame similarly. The white balance is described in temperature units (Kelvin), and in the Protune mode, it ranges between 2300K to 6500K.
The light sensitivity of GoPro sensors can be adjusted using the ISO settings. The ISO parameters in Protune mode ranges from 100 to 6400. In bright conditions, the ISO values should be kept minimum. Moreover, you should progress to higher ISO values in low-light conditions while simultaneously taking care of the exposure compensation.
The high, medium, and low buttons on GoPro will help you adjust the image clarity. You can change the contrast and focus under the sharpness settings of Protune.
The color settings in Protune are simple to understand. You get to choose between two options. One is the GoPro color that automatically enhances the color profile of any image as soon as you click it. The other option is a flat color setting where you get a neutral color profile on which editing can be performed easily.
OTHER GOPRO SETTINGS
Other settings include raw audio settings and microphone settings. These are essential to adjust audio quality while you are recording a video. The reset settings are also available in Protune mode.
