A little off topic, but I recently bought an OM System OM-5 camera which can do similar - it can simulate an ND filter (up to 4 stops, the OM-1 can do up to 6) in camera, I guess with some continuous reading of the electronic shutter trickery, and combined with the really good IBIS (stabilisation to prevent camera shake), you can easily do handheld exposures of 1 second plus in daylight. Really fun effect for street photography if you want to capture people in motion. It can also just capture the maximum brightness of each pixel over the exposure, for easy light trails.
For me being able to do this kind of stuff without needing a tripod or external features was a big selling point of the camera.
There’s an iPhone app called Spectre (from the makers of Halide) which can do long exposures like this too, but I’ve not had the best luck with the results in comparison
- CWuestefeld 3y agoI've got the OM-D E-M1 (from back when it was Olympus). The trick with their algorithm is that it's not simply adding to the frame. It's diffing, and adding whatever's left over. Which, as you note, does great for things like waterfalls. If you've got any interest in astrophotography, I think you might be interested in this [1]. The combination of IBIS with the synthetic high-res mode inherently averages out noise in night sky shots, giving you both higher-resolution and very low noise.

- tomduncalf 3y agoAhh interesting, thanks! I am somewhat interested in Astrophotography though don’t get many chances to practice it as I live in London!
