LECTURE
EXPOSURE SETTING
  • EXPOSURE: In photography, exposure is the amount of light which reaches your camera sensor or film.
  • The main parts of the camera: Camera body, Shutter, Image sensor, LCD screen, Camera lens ,Aperture/ Iris. The camera body is a light proof box.

  • IRIS,SHUTTER, SPEEDISO: There are only two camera settings that affect the actual “luminous exposure” of an image: shutter speed and aperture. The third setting, camera ISO, also affects the brightness of your photos.
  • IRIS: Iris/Aperture is control the flow of light entering the lens
  • IRIS: Iris/Aperture is measured by f-stop, indicated by sequence of f-number: f/1, f/1.4, f/2 , f/ 2.8, f/ 4, f/ 5.6, f/ 8, f/ 11, f/ 16, f/22 , f/32..The lower the f-number, the larger the lens opening.
  • SHUTTER: The shutter is a small plastic sheet that opens and closes to allow light onto the film or prevent light from reaching the film. 
  • SHUTTER SPEED: Shutter speed is measured in seconds: 1/1000 s,1/500 s,1/250 s,1/125 s,1/60 s,1/30 s,1/15 s,1/8 s,1/4 s,1/2 s,1 s, 2 s, 3 s…

  • ISO: Originally referred to the sensitivity of film—it's "light gathering" ability. For digital photography, ISO refers to the sensitivity—the signal gain—of the camera's sensor.

  • ISO: The common ISO camera settings are: 100, 200, 400, 640, 800, 1600, 3200, 6400….
  • The lower the number of ISO the less sensitive your camera is to light and the finer the grain.

LENS PERSPECTIVE
  • The are wide angle lens, standard lens and tele lens.
  • Appropriate lens provided desire framing, lens choice affects angle of view.

  • Different lenses are designed for different for different purposes. Lenses can be categorized by FOCAL LENGTH.
  • FOCAL LENGTH:  The shorter the focal length, the wider the angle of view and vice-versa.
  • FOCAL LENGTH: Focal length is the measurement (in millimeters) from the optical center of a camera lens to the camera’s sensor.

  • DEPTH OF FIELD:  The proportion of the image that is reasonably sharp and in focus.

  • DEPTH OF FIELD:  The smaller the aperture you use, the greater the depth of field.
  • Wide angle lenses are ideal for fitting a large area into your frame. 

  • Wide angle lens is especially useful for landscape photography or street photography. With wide angle lenses, almost everything is in focus, unless your subject is very close to the lens.
  • Standard lens offer a fairly accurate representation of what the human eye sees, both in terms of visual angle and perspective. 

  • Images created by standard lens are perceived as more natural than those taken with other types of camera lenses.
  • Tele lenses are great for isolating a subject that is far away. 
  • Tele lenses allow you to photograph subjects from a distance thanks to their magnification. 
DSLR V.S SMARTPHONE

  • Smartphones vs Cameras = Convenience vs Quality: DSLR cameras are designed to capture images. Phones are designed to carry out a multitude of functions.
  • Phone cameras are very limited by size. The size of the lens and the size of the sensor that captures the photos. Entry-level DSLR have much larger lenses and sensors than mobile phones do.

INTRODUCTION

WEEK 5: Digital Imaging Exercises
PART 1: Hearst Mansion
This is a exercise which is learn how to do the reflection at the apps 'photoshop'. First we start from the element that given from Mr.Fauzi. 2nd exercise we must take photo by ourselves to done the work.
