(8) Sharpness
High/Middle/Low (Default setting: Middle)
Sharpness adjusts the sharpness of the objects in your scene, which is crucial for
capturing the fine details and enhancing the overall quality of your photos or videos.
(9) ISO
Auto/100/200/400/800/1600/3200 (Default setting: Auto)
ISO determines the camera's sensitivity to light and creates a trade-off between
brightness and resulting image noise. Image noise refers to the degree of graininess
in the image. In low light, higher ISO values result in brighter images, but with
greater image noise. Lower values result in lower image noise, but darker images.
(10) Date Stamp
Off/On (Default setting: On)
When Date Stamp is enabled, a time and date watermark will be added to the video
or photo. You can also set it to Off.
