Introduction to DSLR

DSLR camera stands for digital single lens reflex. It's a camera with one lens and a mirror which reflects the light where pictures are recorded on a digital card instead of film. To use the camera, you need to have it set on automatic.

Instructions on how to use it:

Use automatic settings

• Set the dial to the green for automatic mode.
• Make sure the lens is set to AF (Autofocus) not MF (Manual Focus).
• Push the shutter button down halfway, the camera will automatically focus on the subject.
• Push the button down the rest of the way to take the picture.

Exposure

• Overexposed:
• too much light
• makes the image appear washed out                 

Underexposed:

• too little light
• makes image appear too dark

Aperture

• A cameras aperture, shutterpeed and 250 settings directly affect exposure but more importantly, they allow to control how each photo will look.
• Controls size of lens opening that allows light into the camera.
• You can blur the foreground and background that bracket your subject (known as shallow depth of field) by opening up the aperture with a low f stop number.
• You can keep your photo shrap from the foreground through out the background (known as wide depth of field) by closing the aperture down with a high f stop number.

Shutter Speed

• Controls how long the sutter opens to expose the image sensor to that light.
• Open it for just a millisecond and you can freeze a fast moving subject.
• Alternatively you can show the movement of a fast moving object by keeping it open longer with a slow shutter speed.

ISO

• How sensitive your image sensor is to light.
• The lighter the ISO the more sensitive to sensor will be making the image brighter
• The lower the ISO the less light is going to go in it, therefore the darker the image will be.
