I produce videos for my YouTube channel. Many people enjoy videos of driving around in a car, particularly in cities far from their own homes. I live relatively close to New York City and frequently create videos of my travels around the streets of New York City, which many people who don’t live in the city enjoy.I do get complaints from people when I’m driving into the sun, and the sun's glare reflects off the window and the dashboard into the camera. I tested this new lens today and found it to be effective when driving into the sun. It reduces most of the glare from the sun. This will be a very valuable tool for my YouTube business. I always apologize while videoing for any glare they may see.I’m not sure how the technology works. Still, it seems to filter out a lot of the sun’s glare and the streaming that you get from sunlight coming in through your camera through windows and reflecting on other objects. The reflected light is also blocked to a reasonable extent; it's not perfect, but it's much better than this without it. This is a very worthwhile device for anyone serious about taking videos or photographs with an iPhone.
