What is the "resolution" of the human eye?

[Koosh]

Odd question, I'm just wondering at what point does the human eye not notice a difference? Mainly with the use of digital cameras.

Like if you were to take the same 4" by 6" picture with a 5 megapixel camera and a 6 megapixel camera, would there be a major difference?

I understand that the higher the MP, the larger the picture can be blown up without distortion, but what are the advantages if you never use it for anything bigger then an 8X10?

My 2mp camera shows noticeable distortion at 8X10 sizes, but at the smaller 5X7 and 4X6 it looks damn good.

uh there is no real quality difference if you're not making anything bigger than 8x10...unless you're educated in the realm of photography, you won't notice anything.

you also have to take into account the quality of the printing process used.

About 74 megapixels. I'm totally serious too. But human visual acuity is not rated in the same fashion as electronic equipment. It's rated in arc/min. This website describes it:

Pretty interesting stuff!

well it depends. are you using a ati or nvideo card? also depends on the os as well as the memory you have. maybe upgrade your monitor would help.


ok enough nonsense. i have wondered this too. seems like advancements in tv and film are getting better an better and i also wondered when is enough really enough?

oddly enough i learned about this the day the thread started (in astronomy). very cool stuff, cuz it's a measurement present in most optical equipment.

note that this is only true when the item is 20 inches from your face as visual acuity is measured by angles. closer would mean more resolution and farther would result in less. fairly obvious but some people might miss that.
