Getting exposure correct when shooting in high contrast situations—such as landscapes with bright skies and dark foregrounds—is a challenge, we have developed an ND4 neutral density dome lens for all PDS GDome's that will help to:
1. Slow shutter speeds even in bright daylight
2. Allow the use of wider apertures, which result in shallow depth of field.
3. Reduce the amount of light to 1/4 to bring out the colour in otherwise washed out parts of an image.
