"Cameras vs. The Human Eye" Reading Response

The article I read was an analysis of why eyes and cameras process the same image differently. The three main reasons for this are:
  1. Angle of View
    • Cameras have a wide angle of view, compared to our eyes' narrow angle of view
  2. Resolution and Detail
    • Unlike the camera, only our central vision is 20/20, and we only catch 1/10th of the detail anywhere off-center from our eyes.
    • A single glance is only able to perceive the detail of a 5-15 megapixel camera.
  3. Sensitivity & Dynamic Range
    • Our eyes are able to adjust to an image after looking at it. Rather than quickly glancing at something, in the case of letting our eyes adjust, scientists estimate that our eyes can see 10-14 f-stops of dynamic range. I'm still not sure exactly what this means, but according to the article, it is similar to an SLR camera.
MAIN POINT: We should not try to determine whether or not a camera can process an image like our eyes can because photographs have different standards.

Is the goal of future cameras to capture images like human minds can? It would be an incredibly complex and terrifying machine to do so, because it requires a mind to interpret information. New cameras with high megapixels are great and all, but I hope they don't undermine poloraoids and other cool retro photograph quality our parents used.

Since this article, though technically a tutorial according to the website, didn't actually teach me how to do anything (it taught me why things are the way they are), I am posting an image of a scanned polaroid picture that I took a few years back. Poor quality, yes. Undervalued style, yes.
