Hello and Welcome! You’ve reached a blog about the history, physics and technology of photography, optics and computer vision, with the occasional sprinkle of Linux- and machine learning-related topics. Well, sometimes there are also other posts showing some nice photographs or the odd travel-documentary.
For questions regarding my videos please use the form on the Contact page of this website. For freelance-work related questions you can either use that form or my profile on Upwork (rates are lower via my website ;).

Computer Vision: The Camera Matrix [Video]
In this video we start with the pinhole camera model and derive the intrinsic and extrinsic camera matrices. On the way we also talk about homogeneous coordinates and rotations.
Latest Projects
Some projects take quite a while to describe so there are multiple posts. Below you’ll only see the first post of a series. That should make it easier to find the start of a project.
