Marques BrownleeOk but real talk we still don’t know the frame rate, resolution and dynamic range of the human eye?

Imthaz | Tech & PhotographyCan we get @ifixit to do a teardown and give us the deets ?

The Sneak@mkbhd I always figured we can't put numbers on it because it's so messy. We have different parts of the eye with different amounts and types of photoreceptors; each eye has a blind spot; we detect motion differently; the dynamic range is affected by pupil dilation. For frame rate, it's about nerve pulses... do they even fire at consistent rates while watching something? Many light sources flicker faster than we can perceive, which presumably means they're faster than our "frame rate"? Or does our brain actually "see" the flickering and smooth it out for us?
I think it's fun to think about for sure though 🙂
Frederic Barthelemy@mkbhd Does framerate or resolution have a well-defined meaning for analog sensors being observed by a non-frame-based observer?
The fact that we observe things through saccades over a relatively long period of time, means we would definitely have highly variable rates / resolutions depending on if you’re measuring your around the focal point or not, or what your definition of the full frame is.
Marcello Bastéa-Forte@mkbhd I think we do?? But the eye is analog in many ways so things don’t directly map to digital units

@mkbhd “Angular resolution: about 1 arcminute, approximately 0.017° or 0.0003 radians, which corresponds to 0.3 m at a 1 km distance”
Georgi Totev@mkbhd brain makes the real magic, our eyes compared to those of some animals like eagle’s or cat’s are totally imperfect. So like in the devices it is not all about the camera or lenses, but for the unit which processes the information. Even thought we do have HDR constantly. 😅

Hwa YangJerngTell me you didn't bother to google for a biological teardown of the pipeline
Peter Saathoff-Harshfield@mkbhd Important to keep in mind that there’s not just one human eye. For example, I have no central vision, only peripheral vision. I have to look to the side of anything to see it. And, receptor cells work differently and have a different resolution depending on where you are on the retina.
