These 3 Basic Tips will make you understand the simple settings for your DSLR.
Aperture
is referred to the lens diaphragm opening inside a photographic lens.
Open aperture:
- Photo is lighter
- Background is more blurred
- Used for portrait shooting
- Shallow Depth of Field
Closed aperture:
- Photo is darker
- Clearer background
- Used for shooting landscape
- Greatest Depth of Field
Shutter Speed
it is responsible for creating dramatic effects by either freezing action or blurring motion.
ISO
is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera.
Here is the two samples of image with different ISO settings:
ISO 100 is generally accepted as 'normal' and will give you nice shots (little noise/grain). While an ISO over 100 make your shots more grainy and noisy.
Situations where you might need to push ISO to higher settings:
- Concerts - low in light and often ‘no-flash’ zones
- Art Galleries - have rules against using a flash and of course being indoors are not well lit
- Indoor Events - subject is more moving yet having limited light available
To make it simple this Chart shows how Aperture, Shutter Speed, and ISO affect your photos.
Hope it helps. Enjoy! :)
