## Ever an ocular phenomenon?

I'm suddenly curious about something the editors of this page might be able to answer... Are there any circumstances in which motion blur can be "seen" in real life, under natural light? Or is it always an effect of camera capture? (That is, even though nothing physically "blurs," perhaps the nature of human vision could give a blurring effect?) $\sim$ Lenoxus " * " 00:36, 8 April 2008 (UTC)

## /\ Well, no

I think people, while viewing objects at any speed, wouldnt experience motion blur effects. Motion blur basically occurs because there is a retention time on the sensors, so they are sensible to image changes: if something changes position, the sensor will have all those different lights in one image. With out eyes, however, I think thats not the case. Our retinas doesnt really have a big retention time, I guess - it's more time-continuous capturing - more like a cinema camera. We take (consciousness) and remember a few snapshots only. Therefore, we are suceptible to only other efects, like temporal aliasing, when you see fast-moving car wheels look strange.

Im not an expert neighter in vision neighter in nothing, though.

Well, if you wave your hand rapidly back and forth, it does seem to be blurring. I don't know if this would technically be referred to as a different phenomenon than motion blurring, but we certainly do expect to see a blurring and stretching effect as things move too quickly for our eyes to track. --75.9.208.80 (talk) 03:52, 29 September 2008 (UTC)
I agree, and this would imply that humans new of motion blur effects before the invention of cameras. Is there any historical evidence to back this up? What's the oldest mention of motion blur? Mangledorf (talk) 16:43, 29 March 2013 (UTC)
