View Full Version : Ang ating mga mata... Tok Paler 08-01-2006, 11:46 PM We all know that the camera is designed to worked much like our own eyes does. Light enters our eye, hits a photosensitive thingy, etc... etc... But if our eyes were truly a camera, what kind of lens would it have? jojo_mamangun 08-02-2006, 12:12 AM it would be in the range of 24-50mm dave_deluria 08-02-2006, 12:21 AM Hmmm.. I'm gonna take a wild guess on this one... Our eyes perceive a field of view similar to 50mm (in 35mm film format) that's why they call the 50' a normal lens. Aperture wise I would also take a wild guess our eyes have a largest aperture value of F 1.0 so that means a lens with F 2.0 would only allow half the amount of light as the naked eye. Did I get it right? Tok Paler 08-02-2006, 12:53 AM i guess... though i know that our eyes have a shutter speed of 1/60? tama din ba yun? =b i mean, that's why you don't get scan lines from a TV at that shutter speed, dba? =) oo nga noh.. aperture is relative to the sensor size, dba? so an f2.8 on an EVF camera has a smaller opening than the same value on a 35mm or a DSLR. tama ba yun? is the circle of confusion on a camera lens similar to our eyes? jEnNiFeR_gALaNg_sAnToS 08-02-2006, 05:38 AM 4 me i think its a 180 degrees panoramic view (f u use ur both eyes) kc i can't help it notice d side image sa mga side of my eyes unless u focus on a subject only sort of a blur na yun both sides mo... confusing no?!!! f ever one eye naman definitely 24-50mm range nya...(fr my eyes..dunno urs :) ) nap_alcedo 08-02-2006, 05:45 AM Hmmm..

Dave, I think all you have to do is to ask Hector....:) Nap laszlo lim 08-02-2006, 08:51 AM 4 me i think its a 180 degrees panoramic view (f u use ur both eyes) kc i can't help it notice d side image sa mga side of my eyes unless u focus on a subject only sort of a blur na yun both sides mo... confusing no?!!! f ever one eye naman definitely 24-50mm range nya...(fr my eyes..dunno urs :) ) i remember reading somewhere that we do have vision up to 180 degrees. that's why when we use a fisheye lens, the view or the image gets that cool distorted look. :) Tok Paler 08-02-2006, 03:48 PM didn't kodak make one of those stereoscope cameras? Jun Tordillo 09-09-2006, 04:16 PM Our eyes: On the bright side: Best VR/IS there is Most accurate dynamic focusing system Waterproof, albeit you need an adaptor to make it effective UW(mask or gogles) Bad side: No Manual focus No aperture ring IR not possible Thats all I can think of for now :) Jun T jose_deluna 09-09-2006, 05:14 PM @JunT I beg to disagree on the "no-IR" function... pagka-alam ko napakaraming merong IR-function ang mata... sobra pa nga sa pagka-IR kung makatitig... he he he (just kidding). Other than those mentioned... (hindi lang tungkol sa mata bilang lens)... the human eye and human mind as a camera... - excellent at di-matutularan na metering mode (light and color meter) - lamang na lamang pa sa sRGB or Adobe RGB color scheme - excellent contrast rendition - unmatched image buffer memory Pero meron din namang downside... - built-in fog filter... may cataract - built-in polarizer... laging naka-shades - mis-focussed at doble-vista... duling - extreme distortion and vignetting... banlag - totally dark view... bulag - incorrect color scheme... color blind ***note: not intended to offend anyone... just comparing similarities of camera lens to human eye...
