*Below is the original image without any parameter modification.
3.1 Hue
This term can be simply taken as different colors perceived by human beings. To adjust the value of hue is to adjust the color of scene.
Usage scenario: You can adjust the hue of the picture by changing the hue value, such as yellow tone or pink tone, etc.
3.2 Brightness
Brightness refers to the degree of light and darkness of the scene or image. When the brightness of image increases, it will appear dazzling or harsh; and the less brightness, the grayer the image will appear.
Usage scenario: When you use the VM33 camera to shoot indoors in low light or outdoors in too much light, you can adjust the brightness to get the best results.
3.3 Contrast
Contrast is the ratio of black to white on the screen, which is the gradation level from black to white. The larger the ratio, the more gradations from black to white, and thus the richer the color expression.
Usage scenario: By adjusting the contrast, you can adjust the overall lightness and darkness of the image captured by the VM33 camera, as shown in the picture below.
3.4 Saturation
Saturation refers to the vividness of the color, also known as the purity of the color. Highly saturated colors include red, green, etc. Completely unsaturated colors have no hue at all, such as the various grays that lie between black and white.
Usage scenario: When you shoot videos about food or landscapes, etc., you can make the images more appealing by turning up the saturation.
Note that the image turns black and white when the saturation is adjusted to the lowest level.
3.5 Mirror and Flip
Mirror and Flip are the parameters used to adjust the image orientation. With the original settings, the VM33 camera shoots in the same direction as the picture you see with your naked eye.
3.6 WhiteBalance, Exposure, Antiflicker and HDR Mode
White balance is a way to balance different color temperatures and correct color shifts.
VM33 cameras have automatic white balance technology, and this mode is more suitable for outdoor areas with plenty of light. You can choose to manually adjust the white balance value according to your usage scenario.
Controlling exposure is one of the main ways in which the camera controls light. Exposure affects the lightness or darkness of the image. The greater the exposure, the brighter the image.
Anti-flicker technology of VM33 allows the camera to shoot under light without the horizontal flicker that occurs in images under the influence of AC current.
HDR, short for High Dynamic Range, refers to the ratio between the brightest and darkest parts of an image and can make the brighter parts of an image brighter and the black parts darker and deeper.
HDR technology optimizes the display of more details and further enhances the contrast of the picture for a stunning visual impact.
Usage scenario: When using the VM33 to capture fine artwork details, you can choose to turn on HDR mode to enhance the picture.
