4. Light sensitive Medium.
•Many substances are affected in some way by light. The light-sensitive substances used in photographic film to record an image are
silver salts and are called silver halides.
•Digital camera's sensor is photosensitive. When light photons are collected in the photo sites or pixel, a tiny electrical charge is
produced. The brighter the light, the more photons are collected, and a higher electrical charge is generated.

5. Know your gear.

6. Know your gear.

7. SHUTTER

8. EV (Exposure value)
•Exposure value is the measurement of light entering into the sensor.
•They’re denoted in EV units.
•0 EV denotes that the image is properly exposed.
•+ EV denote brighter or overexposed Images.
•- EV denote darker or underexposed Images.

9. Exposure triangle
•This triangle shows you the three main components of image capturing: ISO, Shutter Speed, and Aperture. All three use light to allow
images to be taken.

•Shutter speed is the amount of time a camera’s shutter stays open.
•They’re measured in fractions of a second.
•A faster shutter speed lets in less light, but gives you a sharper image as the subject is ‘frozen’.
•A slower shutter speed lets in more light, but gives you a blurrier image.

11. Shutter speed

12. Aperture
•Aperture is a measure of how open or closed the lens’ iris is. They’re measured in F-number (Eg. F/1.8).
•A wider aperture (or lower f-number) means more light will be let in by the lens, simply because the opening is larger. A narrower
aperture (or higher f-number) allows less light to reach the sensor.
•Narrower apertures (higher f-numbers) give a greater depth of field, allowing more of a scene to be in focus. Wider apertures (lower
f-numbers) create a narrow depth of field, which can help isolate a subject.

13. Aperture

14. ISO
•ISO is your camera’s sensitivity to light. The lower the ISO number, the less light is hitting your sensor. The amount of light in your
scene is important, and your camera sensor will tell you how much is enough.
•Higher ISO numbers allow you to photograph in low light conditions, yet these settings bring more grain.

17. Shooting modes
There are 4 Major types of shooting modes.
•Programmed Auto
•Shutter Priority
•Aperture Priority
•Manual

18. AF-Points
•Autofocus points are what the camera uses to focus on a subject.
•You can choose a single AF point, or a zone of AF points, or let the camera decide which object to focus on.

20. Rule of Thirds

21. Rule of Thirds

22. White balance
•The way our eyes see color is very different from the way our digital devices decode it.
•Different light creates a temperature hue in your image. The color temperature scale used for light is the Kelvin Scale. At the lower end of the
scale, 2000-4000k shows warm light of reddish yellows. At around 5500k, the color is pretty much what we see at noon on a sunny day.
•As the scale climbs, the light gets progressively bluer. At about 10,000 K we reach the very blue light of a typical flash gun.
•Our cameras have a sensor that determines what the color cast of the light is. We can let that sensor to select the right camera white balance.
We do this by using the AWB (auto white balance) setting.
•Sometimes, AWB does not work like it’s supposed to. In that case, different scene modes can be used.

24. OTHER THEN CAMERA
•A tripod - landscape & Product photographer’s best friend
•Bags - shoulder bag, rolling bag
•Memory cards - Get a fast card, burst photos.
•Extra Batteries - one spare battery-Off-brand batteries are usually cheaper
•Polarizing filter - cheap polarizer will harm - same thread size as your lens
•Flash - Flashes can be expensive – it used in weak ambient
•Better computer monitor - IPS -'Panel technology', LED 'Backlight technology’
•Cleaning kit - Microfiber cloth for lens, Rocket Blower to remove dust
•Other equipment - countless photography accessories

25. 10 TIP FOR BEGINNERS
1.Buy interchangeable lenses Body - try out
different types of photography
2.Consider a tripod - Use your camera’s timer
function
3.Keep your camera with you all the time -
unexpected opportunities
4.Make a list of shots you’d like to get – Note the
places you’d like to come back and shoot
5.Often a simple subject makes the best shot

26. 6. Enjoy the learning process - you’ll see opportunities you never
noticed before
7. Take advantage of free resources to learn – Review regularly
8. Experiment with your camera’s settings - Read the manual - 9. Learn
the basic rules -  You have to know the rules before you can break
them
10. Take photos regularly - so you don’t forget what you’ve learned
