<title>Brightness</title>
<p>Increasing the brightness will make the photos and videos lighter. However, if you are in a dark room, increasing the brightness might make the image look more noisy.</p>
</item>
<item>
<title>Contrast</title>
<p>Setting a higher contrast will increase the difference between darker and lighter colors. If the image looks washed out, try increasing the contrast.</p>
</item>
<item>
<title>Hue</title>
<p>Changing the hue of the image will add a tint to it. If image seems to be the wrong color (for example, too yellow), try changing the hue.</p>
</item>
<item>
<title>Saturation</title>
<p>Reducing the saturation makes the image less colorful. If colors seem too harsh, reduce the saturation.</p>
