What's better resolution? My Iphone 5 camera or my eyes
So basically, i took some photos with my iphone 5 the other day and i happened to notice that it was such clear resolution, it actually seemed better than my eyesight! Could it be that apple have actually developed a camera that is betetr than the human eye!
No not yet
No. Not even my Sony Bravia Plasma T. V. Has a better picture than real life.
Is this a joke?
The average human retina has five million cone receptors on it. Since the cones are responsible for color vision, you might suppose that this equates to a five megapixel equivilant for the human eye.
But there are also a hundred million rods that detect monochrome contrast, which plays an important role in the sharpness of the image you see. And even this 105MP is an underestimate because the eye is not a still camera.
You have two eyes (no kidding!) and they continually flick around to cover a much larger area than your field of view and the composite image is assembled in the brain - not unlike stitching together a panoramic photo. In good light, you can distinguish two fine lines if they are separated by at least 0.6 arc-minutes (0.01.Degrees).
This gives an equivilant pixel size of 0.3 arc-minutes. If you take a conservative 120 degrees as your horizontal field of view and 60 degrees in the vertical plane, this translates to…
576 megapixels of available image data.
Curiously - as a counterpoint to this - most people can't distinguish the difference in quality between a 300dpi and a 150dpi photo when printed at 6x4", when viewed at normal viewing distances.
So: although the human eye and brain when combined can resolve massive amounts of data, for imaging purposes, 150dpi output is more than enough to provide adequate data for us to accept the result as photographic quality.
But don't forget that women have more cones than men and men have more rods than women - again, no kidding. Therefore women see colors brighter than men but can't see as well when it gets dark.
Now, if we could only see as well as birds can… : )
Human eyes can be considered as nearly 576 megapixels. With the sensitivity, contrast range so high that the the most power SLR can't't match.
So maybe, or its a good idea to visit a eye doctor soon.
Samsung!
You also use your eye to view the photo, so even if it had a better resolution than your eye then you wouldn't be able to see it any more clearly than anything else. After all, "reality" has an nearly infinite resolution, with pixels the size of atoms. No photo can beat that.
The reason why these photos look nice is that they use post processing to enhance contrast and edge sharpness, as well as saturation.
A bit of slider pushing in a decent post processing software such as Adobe Photoshop or Lightroom can do this to nearly any photo.
Don't be silly.
Unless you're blind, then no. Apple are nowhere near designing a camera that's as good as the human eye.
You can't compare it that way because the processing is done in a different way with acuity being much better at the fovea than in the outer areas.

If you are looking at your I phone photo with your eyes, how could you possibly judge that the resolution is better than your eyes? You didn't really think this through did you?
- Why doesn't the iPhone 6 have 1080p resolution? Ever since 2013 all flagship phones have 1080p resolution or above. Why is the iPhone 6 an exception?
- Why are the colors and resolution on my iPhone so much better than on my laptop? I'm a photographer (and yes, I know I should be editing on a desktop) and when I post photos it seems like the colors are much deeper and the resolution is much more clear on my iPhone than they are where I edit them… On my laptop. Which device is "off"? Will they be closer if I were to edit on a desktop (I'm in the process of saving up for one)?
- Which camera is better: An old General Imaging x500 Digital Camera or an iPhone 7 front camera? It looks like an iPhone only offers 7 MP while this camera boasts 16 MP but this camera is so old and looks worse at least on its own screen. I'm confused
- What is the best bang for your buck video camera for retro style filming at 24 fps, 4K resolution, and no camera judder? Below $1,250? I use an anamorphic adapter lens for an iPhone 6s Plus(+filmic pro) and while the footage is 10 times better than basic iPhone footage, I can't help but notice the jerkiness of edged objects at 24 frames even when I'm holding the phone as still as I can. I've experimented with different frames, shutter speeds, ISO
