Discussion Overview

The discussion revolves around the comparative capabilities of cameras and human eyes in perception. Participants explore various aspects such as light gathering ability, image resolution, subject resolution, and speed of capture, considering different contexts and criteria for evaluation.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that cameras can outperform human eyes, but criteria for comparison need to be established.
  • Light gathering ability is influenced by aperture size and sensor ISO rating, which some argue gives cameras an advantage in certain conditions.
  • Image resolution varies between human retinas and cameras, with cameras being measured in megapixels.
  • Subject resolution can be enhanced in cameras through the use of telescopic or microscope lens systems.
  • Cameras can capture high-speed subjects more effectively due to advanced flash systems.
  • One participant asserts that cameras have been superior to human eyes since the 1930s in specific contexts, such as distance and microscopy.
  • Another participant expresses a personal preference for human eyes, citing the advantage of the human brain interface.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether cameras are definitively better than human eyes, as opinions vary based on specific criteria and contexts. Multiple competing views remain regarding the advantages of each.

Contextual Notes

Participants mention various factors that influence performance, such as the type of subject being observed and the specific technology used in cameras, indicating that comparisons may depend on situational variables.

There is probably a language barrier here, but the general answer is yes. But the criteria for judging should be given.

I believe your asking when can a camera see better that human eyes.
It depends on what you're looking at.

Light gathering ability:
- a combination of the aperture size (f-stop) and film/retina/sensor ISO rating.

Image resolution:
- retina has a variable resolution, cameras are measure in MegaPixels.

Subject resolution:
- Cameras can be outfitted as telescopic or with microscope lens systems.

Speed:
- Cameras and flash systems can capture images from high speed subjects.

Taking a conclusion, is it better than the human eye?

Yes, Scott put up here. Thanks, Russ!
 
Short answer: cameras 'saw' better than human eyes starting back in the 1930's.

Better at distance (telephoto, Zeiss lenses for early Speed Graphlex), resolution(microscopy).
This thread has given several members concerns and we now have good answers. Thread closed.

I would not want to trade in my eyes for a camera.
Human eyes have a huge advantage: The have a human brain interface.
