Here is my post on the Guild.
The short version is, a local student has access to a high speed camera capable of up 1/80000 shutter speeds at 4000fps, 20x shutter or 8000fps, 10x shutter. Either way, this should be sufficient for stopping a paintball in it's tracks.
So what do you want to see filmed and can you help? Read the thread on the guild for some ideas so far and let me know what we are forgetting.
I'd also like to find(ie:beg/borrow/steal) one of those clear barrels AGD used for testing and/or a cocker threaded version. The mag version may be perfect for bolting up to a mag and an ion for in breech tests and the cocker would be great to test for differences between various guns and finally put a lot of hype to rest for at least another few years.
