The document covers the fundamentals of photography, including its history, how cameras work, and various photography techniques. It discusses the evolution of photography from early inventions to digital technology and explains key concepts like exposure, composition, and image editing. Additionally, it highlights the importance of creativity and perspective in photography through various quotes and personal reflections.

4.  Science, art, and practice of creating durable images by
capturing light.
 Greek words meaning “Drawing with light”
 A lens is used to focus the light reflected form an object.
 A photo/light sensitive surface is used to capture the
reflected rays.
 Used in many fields of science, business, art, and many
more.

8.  British inventor Thomas Wedgwood used SILVER
NITRATE to capture the very first photograph.
 The picture faded with time and was able to not capture
shadows
 French inventor Joseph Nicéphore Niépce was the first
man to make permanent photoetching.
 “View from the window at Le Gras” was the first
permanent photograph by Niépce

10.  First permanent photograph.
 Long exposure of at least 8 hours and sometimes
several days.
 Thus introduction of Silver Halides took place in
Photography.
 Later photosensitive plates were made in a manner that
it only took minutes of exposure only

14.  A digital camera uses an array of millions of tiny light
cavities or "photosites" to record an image.
 Upon clicking the shutter button the photosites open and
collect as much light as possible and upon releasing the
photosites closes.

15.  The array decides the quality and type of the image.
 The above array shows that every photosite collects all
the photons be it red green or blue so the image
produced will be a gray scale photograph.

16.  The array with a specific color filter on top is required to
get a color image.
 The above array shows that each photosite collects only
a certain type of photo. Thus in this case the image
produced will be a color photograph.

20.  The ISO speed determines how sensitive the camera is
to incoming light.
 Higher ISO means more noise in the picture, thus in
most cases lower ISO is always preferred.

21.  The shutter speed specifically refers to how long this
light is permitted to enter the camera. "Shutter speed"
and "exposure time" refer to the same concept.
 Slow shutter speed and Fast shutter speed

22.  A camera's aperture setting controls the area over which
light can pass through your camera lens.
 Specified in terms of an f-stop value.
 In photographer slang, when someone says they are
"stopping down" or "opening up" their lens, they are
referring to increasing and decreasing the f-stop value,
respectively.

23.  The range of distance over which objects appear in
sharp focus is known as the DEPTH OF FIELD
 A camera's aperture setting is what determines a photo's
depth of field.
 Lower f-stop values correlate with a shallower depth of
field.

25.  The rule of thirds is a powerful compositional
technique for making photos more interesting
and dynamic.
 It's also perhaps one of the most well known.

26.  The rule of thirds states than an image is most pleasing
when its subjects or regions are composed along
imaginary lines which divide the image into thirds — both
vertically and horizontally.

27.  Off-Centre Subjects Can Give a Sense of Direction.

28. 

29.  High dynamic range (HDR) images enable
photographers to record a greater range of tonal detail
than a camera could capture in a single photo.

30.  Image compression –JPEG
 The RAW file format is digital photography's equivalent
of a negative in film photography.
 It contains untouched, "raw" pixel information straight
from the digital camera's sensor.

31.  Tone, Contrast, Sharpening, and Resizing
 Digital Panorama (Photo Stitching)
