Photography
Photography History
The word
photography

comes from two ancient Greek words:
photo
, for "
light
,"
and
graph
, for "
drawing
.
Photography History
Camera obscura (Latin: "dark chamber") (used by Leonardo Davinci)
Silver Compound
Calotype Process & Salted Paper Printing
Daguerreotype (silver plates)
Plastic roll films
Good gear doesn’t necessarily make
a good photo.
The camera is only a part of the equation.
The camera is a tool. A DSLR set to "Auto" is only marginally better than a point-and-shoot.

Does gear matter?
DSLR
DSLR stands for “Digital Single Lens Reflex”
Faster performance and ability
Control more settings
The use of different lenses for different kinds of shooting (landscape, portrait, macro …)
Ability to shoot in RAW format
RAW vs JPEG
How DSLR works?
Lenses
Focal length & Angle of view
The focal length of your lens essentially determines how ‘zoomed in’ your photos are and determines the angle of view (the amount of a scene that a lens can take).
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
Controls the amount of light entering your lens
Controls the depth of field
Large aperture = Small f-number = Shallow (small) depth of field
Small aperture = Larger f-number = Deeper (larger) depth of field

Zoom vs Fixed (Prime)
Aperture
Shutter Speed
ISO
ISO is the level of sensitivity of the camera to available light.
Higher sensitivity adds grain or “noise” to the pictures.
Fast shutter speed ==> freeze action
Slow shutter speed ==> motion blur
Landscape photographers intentionally use slow shutter speeds to create a sense of motion on rivers and waterfalls.
Composition
Guidelines
Rule of third
Backgrounds
Framing
View Point
Lines & Shapes
Symmetry & Patterns
Break the Rules

Check for Distractions
Fill your Frame
Selecting your viewpoint, the position from which you photograph the subject, is a very important part of composition.
The lines that can be found in images are very powerful elements that can add dynamic impact to a photograph in terms of mood as well as how they lead an image’s viewer into a photo.

Horizontal Lines
Vertical Lines
Diagonal Lines
Triangles
Symmetry
Patterns
There really is no right or wrong way to compose an image, but there are
better ways
to do so.
Some composition techniques can make a huge difference to an image and take it from being a snapshot to becoming a truly great photo.
The important thing is to experiment with these techniques, combine them wherever possible.
known as “
exposure time
”, stands for the length of time a camera shutter is open to expose light into the camera sensor.
