Hi Everyone in this presentation you will find the comparison between Human eye V/S camera and DSLR . I hope you will like my work . for any queries and suggestions write me on :- ayusharyan7 428@gmail.com or Instagram :- ayusharyan_4040 Thank you and Regards, Ayush Aryan

1. COMPARSION BETWEEN EYE AND
CAMERA

2. What’s the difference between a camera and a human eye?
Or: What’s the ISO of a human eye?
I have worn glasses all my life, and as a result, I was introduced to the magic of optics way
before I ever considered getting into Then, when I started learning more about the magic of
photography, I started noticing things with my own eye-sight: For example, in bright daylight, I
can see further than in twilight. Why? I’ll leave you to solve this one yourself (think about
it!)—the solution is at the end of this article.

3. A quick anatomy refresher As a photographer, I’m often intrigued by the physics of how photography is
similar (and different) to how my eyes work—so I figured it was time to write a little article about how it all
hangs together. Camera vs. Eyes: Similarities To better understand the answer to this question, let’s first
have a quick comparison of various similarities and differences found in the working of the human eye and a
photo camera.

4. Iris and Aperture
The aperture is to the camera as the iris is to the eye. The aperture
size refers to how much light is let into the camera to be reflected on
the sensor or film. As with the human eye, when the iris contracts
itself, the pupil becomes smaller and the eye takes in less light. When
the iris widens in darker situations, the pupil becomes larger, so it can
take in more light. The same effect happens with the aperture; larger
(lower) aperture values let in more light than a small (higher) aperture
value. The lens opening is the pupil; the smaller the opening, the less
light let in.

5. What is Aperture?
Aperture refers to the opening of a lens's diaphragm through which light passes. It is
calibrated in f/stops and is generally written as numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11
and 16. Lower f/stops give more exposure because they represent the larger apertures,
while the higher f/stops give less exposure because they represent smaller
apertures. This may seem a little contradictory at first but will become clearer as you
take pictures at varying f/stops. Be sure to check your manual first to learn how to set
Aperture Priority for your camera, then try experimenting to get comfortable with
changing the aperture and recognizing the effects different apertures will have on the
end-result image.

6. Camera vs Eyes
Similarities To better understand the answer to this question, let’s
first have a quick comparison first various similarities and differences
found in the working of the human eye and a photo camera.
Image focusing: Human and camera lenses both focus an inverted
image onto light-sensitive surface. In the case of a camera, it’s
focused onto film or a sensor chip. In your eyes, the light-sensitive
surface is the retina on the inside of your eyeball.

9. Digital single-lens reflex
A digital single-lens reflex camera (also
called a digital SLR or DSLR) is a digital
camera that combines the optics and the
mechanisms of a single-lens reflex camera
with a digital imaging sensor, as opposed to
photographic film.
