At some point, many of us will have a camera that just doesn’t feel right when it comes to shutter speeds. Maybe we’re seeing flicker when we’re shooting timelapse, or perhaps we have an old camera that doesn’t seem as quick anymore.
In the olden days, confirming shutter speeds was no easy feat. It required some specialised hardware and a book of charts to compare. These days, you can do it with an Arduino and a couple of lasers. This project by Stuart Brown shows you how.
