  <title>My photos and videos look wrong</title>

  <p>If your photos or videos are too dark or the colors seem to be wrong, try
  adjusting their saturation, contrast, brightness and hue:</p>

  <steps>
    <item>
      <p>Press the menu button in the top-right corner of the window and select
      <guiseq><gui style="menuitem">Preferences</gui><gui style="tab">Image</gui></guiseq>.</p>
    </item>
    <item>
      <p>Move the sliders to find the best settings for your webcam.</p>
    </item>
    <item>
      <p>Click <gui>Close</gui> and check to see if the preview looks
      better.</p>
    </item>
  </steps>

  <figure>
    <title>Different options under <gui>Image properties</gui> (left to right):
    applying brightness, contrast, hue and saturation</title>
    <media its:translate="no" type="image" src="figures/image-properties.png" width="800" height="150"/>
  </figure>

      <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>
    </item>
