Digita l Photography
Whether youre shooting with a camera on a cellphone, a point & shoot
camera or a high-end Digital SLR camera, the principle is this
Light enters the camera through a lens and hits a sensor, that forms thefinal image.
Process the images through software like Photoshop to produce your finalpicture (DEVELOPING).

Overal l Sett ings
SET YOUR CAMERA TO CAPTURE AS
MUCH INFORMATION AS POSSIBLE
Megapixels
Better to shoot in the highest qualitysetting that your camera will alloweg. 5184 x 3456 FINE (the higher the
better, since you can throw awaymore pixels if you have to crop)
RAW or JPG?
JPG is perfectly OK for most practical

Overal l Sett ings
SET YOUR CAMERA TO CAPTURE AS
MUCH INFORMATION AS POSSIBLE
Colour / B&W?
Shoot colour you can always turnthe image into B&W later but youcant do the reverse
Set Date / Time on the Camera
Getting a faster memory card will help

Shot Sett ings /Concepts
SET YOUR CAMERA TO THE OPTIMUM
SETTING FOR THAT PARTICULAR SHOT
Shutter speed (S or Tv)
Expressed in seconds (1/4000, 1/300,1/60, 1/5, 1, 5, 30)
Affects how long the camera isrecording the image and alsobrightness
Fast / high speed = Light enters for
short time freezing motion use in

Slow Shutter Speed
Note the streaks produced by moving vehicles.
-

Fast Shutter Speed
At 1/4000th of a second, you can capture
segments of the display on an auto meter asthey light up.

12/35
Aperture
Aperture (A or Av) Expressed with f number (f1.8, f2.8, f5.6)
Meaning = How much the lens opens up
Affects Depth of Field (how much of the imageis in focus) and also brightness
Smaller f number = Higher opening shallow
depth of field brighter Higher f number = Smaller opening more
depth of field darker

Lens Apertures
F 1.8 F 4.5 F 22
-
8/6/2019 2011 08 07-Photography PPS
14/35
Concepts
ISO Light sensitivity affects brightness
Expressed as a number ISO100, ISO200,
ISO3200
Higher numbers work better for low light butalso produce noise
Exposure Overexposed = too bright
Underexposed = too dark
White Balance
-
8/6/2019 2011 08 07-Photography PPS
15/35
Concepts
Settings Usually, Program Mode + Flash Off works
well for most practical purposes
Else, depending on the effect you want, useshutter priority or aperture priority and playwith the white balance
Try out some test shots wherever youare... will help in ascertaining a goodset of settings

Taking the Shot
Taking the shot
Tell your subjects to say CHEESE
Hold the camera as still as possible /use a tripod or place it on a flat surfaceif you have to
Use the lines / grid in the viewfinder toalign straight edges as much aspossible
Take the shot
-

Holding the Camera
Use both hands as far as possible, holdthe grip with the right hand andstabilise with the left hand
-

18/35
Using the Viewf inder
Line up objects (look for walls, floors,doors or other straight edges), grid willalso help you apply rule of thirds
-
8/6/2019 2011 08 07-Photography PPS
19/35
Concepts
TELL A STORY THROUGH THE PHOTO.
SHOW ONLY WHAT IS REQUIRED AND GUIDE
THE VIEWER TO SEE. DONT CONFUSE THE
VIEWER.Composition (applies to still images andvideo too)
Horizon / Straight Lines Include relevant elements (your subject
and anything else that is pleasing) andeliminate distracting elements
Use Depth of Field to your advantage
-

Rule of Thirds
Visualise two horizontal & two verticallines in the frame
As if they are dividing up the frameinto 9 equal areas
Position subjects of interest at theintersecting points
Enabling the display of a GRID in yourviewfinder will help
