Thanks!Yeah, once you get into ultra high frame rates there is the challenge that there are only so many photons :). Physics begins to limit how good of an image is possible when you only collect photons for a half millisecond, as required for true 2000 frames per second. (You can kinda fake 2000 frames per seconds with longer but overlapping collection times, but that then blurs in the time dimension, which is exactly what you don't want when trying to capture ultra-slow-mo!!)There two great ways to address the lack of photons:1) Crank up the light!! This can be done in many lab scenarios, but is extremely challenging in the real world.2) Reduce the spatial resolution. This is literally making the pixels larger, which means that each can collect more photons in a given amount of time. For many diagnostic purposes, this works great, and is exactly what I would do if I ever managed to make a setup to capture what happens in a binding release. But as a Film Maker, this seems non-viable. People don't want to watch low resolution films!
