I have been following the Mathphotographer YouTube channel for several years. Although the channel covers an impressive range of high-end camera equipment across multiple brands, its center of gravity always seems to be Leica.
For a long time, the person behind the channel remained something of a mystery. We now know that Mathphotographer is Mathias Born of Switzerland. Until recently, he preferred to stay behind the camera, revealing little of himself beyond his thoughtful narration and careful analysis. It has been enjoyable to finally put a face and a name to a voice that many photographers have been listening to for years.
