Focus

Once the aperture is set on a camera, you should adjust its focus to ensure it is picking up a crisp image.

While setting the focus, it may be helpful to switch the camera to video mode in order to see the recording volume more clearly, or to intensity mode, which can be especially useful when the video image is dark.

As with aperture, the focus is set in QTM for cameras with motorized lenses and inside the flash mechanism for cameras with manual lenses.

The goal of focusing is to view a clear image of the markers with sharply defined edges.

If you have a large recording volume, it may not be possible to get all of the markers in focus at once, so prioritize those nearest to the camera.

Switch back to marker mode and double-check the aperture before proceeding to the next camera.

If your cameras have manual lenses, remember to close the flash mechanisms and lock them back into place once you’re done.
