QUESTION: Hello Chet,
When filming a sunrise or sunset, what kinds of protective filters should be used to avoid damage to camera components?
ANSWER: First, please check the Owners Manual for your camera. The older model cameras could/will be damaged by pointing directly at the sun. The newer CCD or MOS image sensors have less or no issue in this regard, but again best to check with your camera manufacturer to be sure.
