He's using digital single-lens reflex cameras with moving mirrors in an application where you don't need that, but do need a good camera. What do you use today when you need a good camera with no user interface?

define good camera.

it's a bit weird because it often turns out that cameras with user interfaces are cheaper because of economy of scales. that being said, a market for almost barbone sensors on pcb's seems to be building and is lead by raspberry pi's camera modules, where the hq module has a reasonably sized sensor but is still a far cry from mft, aps-c and full frame sizes. the hq camera is almost on parity with most phones. from there it pretty much moves into cameras with ui's but controllable with some kind of vendor sdk or libgphoto. i imagine it's a matter of economy of scale and it's almost impossible to buy a good almost barbone sensor. If it's even possible e.g. the 61mp ff sensor used in the Sony a7rV is available almost barbone for astro photography, it's still very expensive. i imagine there's a pretty big market for all kinds of industrial cameras but from tip toeing into that, it seems very very very expensive.

That camera had an MSRP of $899 when it was new in 2006 [0]. Amazing that they now sell for only £50, and still take fantastic pictures even by today's standards [1]. Technological progress is nothing short of remarkable. [0] https://kenrockwell.com/canon/rebel-xti.htm [1] https://onfotolife.com/camera_sample_photos?camera_id=30&pag...

Even more impressive when you account for 50% USD inflation since 2006: https://www.in2013dollars.com/us/inflation/2006

A similar effect is achieved with a platform and a camera on an arm rapidly rotating around the platform. I've seen it at tech conferences. I think this is it: https://spinpix360.com/

this is interesting but it doesn't have the time freeze or slo mo effect done with a rapid series of photos.

Nice, but aren't the cameras supposed to be triggered in sequence instead of all at once? I thought there was still a little bit of motion in the movies, but in these the subjects all freeze in place.

One would think the cameras all record at the same time and you can just pan around and adjust speed whenever?

yes. in the special edition DVD, the special features show the bullet time scene in the studio and you can hear the shutters from the camera clacking like dry fire from an automatic rifle

Technically yes but since the resulting bullet time sequence is really short, it won't make much of a difference, I think.
