Re: Cameras and Eyes
Arguing about a camera being superior to the eye is silly.imo
Apples and oranges. There are many many man made devices that perform tasks and operations in greater number and more efficient.
However I'll play along, can a camera do all the things a eye can do with no one there to build it or power it, program it and operate it?
The eye can, you see it is linked to this pretty cool automated intergrated system called the human body.Oh there are also some models custom made for raptors and large preditory cats.

Re: Cameras and Eyes
Hi Panda, Separating the eye from the body as you know renders it inoperable. It is built to operate as a contiguous unit and therefore your argument is empty imo. I can just as easily turn your own statement around and say take a SLR lense from its body and see what it can do.

your argument is that a human is better than a camera?
Well, that is nice goal-post moving.

Well yeah, a human is a intergral part of the eye. No goal post moving required.
Just as a power supply, lense and all other integral componants of a camera are essential to it's operation.

Panda writes:

To answer your 'adjusted' comparison: a camera
used by a human is better than an eye used by a
human

yes it is.

Panda writes:

An eye is not equivalent to the lens in a
camera.
An eye is equivalent to the whole camera.

an eye is equalvalent to a camera? Nope this is the false analogy
because from the start your equating a fully funtioning camera to a eye that is incomplete. Lacking it's needed vasculature, nerves, sensory inputs, etc..

Re: Cameras and Eyes

I equate a fully functioning camera to a fully functioning eye.

Hence you have reached the conclusions you have.

A fully functioning eye is dependent on a fully functioning optic nerve, brain function, cardiovascular system and metabolic system aka: life support system and housing and sensory input output unit for the eye. Aka: the human, cat or bird or what ever.

The analogy is inadequate. The camera can do many many things better than the eye. But it can not make itself, repair itself, program itself, it is a tool and nothing more.

Yes a human operating a camera is superior in vision to a human without a camera.

Thats why we made them.
