We all harp on about the latest 4K this or 8K that. But do we really know what we’re saying? Most of the time, probably not. It all comes down to how the camera’s sensor actually records each of those pixels in the image, which is largely guesswork.

In this video Cooke Optics interview cinematographer Geoff Boyle. He explains that it’s basically all down to the nature of a Bayer pattern filter array. What’s really happening when your sensor sees an image and why your camera’s resolution is lying to you.

Light pollution is one of the main problems of every astrophotographer, no doubt about that. If you want to get rid of its orange-yellowish tint, you need either post-processing or a filter. We have recently presented you with PureNight Premium, a filter you can attach to your camera and reduce the effects of light pollution. It’s mounted onto your lens by using a standard square filter holder.

But Cyclops Optics, a Hong Kong-based company has another solution. They produce filters that can be clipped on – but onto your camera’s sensor.
