<title>How do I calibrate my camera?</title>
<p>
Camera devices are calibrated by taking a photograph of a target
under the desired lighting conditions.
By converting the RAW file to a TIFF file, it can be used to
calibrate the camera device in the <gui>Color</gui> panel.
</p>
<p>
You will need to crop the TIFF file so that just the target is
visible. Ensure the white or black borders are still visible.
Calibration will not work if the image is upside-down or is
distorted by a large amount.
</p>
<note style="tip">
<p>
The resulting profile is only valid under the lighting condition
that you acquired the original image from.
This means you might need to profile several times for
<em>studio</em>, <em>bright sunlight</em> and <em>cloudy</em>
lighting conditions.
