Each camera has three basic parts – the lens, the body, and
the viewfinder. The lens is what lets light into the camera. The body is
basically the brain of the camera – it records the images that the lens sees.
The viewfinder shows you what the lens is seeing.
The Canon T3i is a DSLR camera – DSLR stands for Digital
Single Lens Reflex. This means that there is a mirror inside the camera that
reflects up to the viewfinder and shows you exactly what the camera lens will
see. This also means that it is digital – instead of recording images to film,
the images are recorded to a memory card. This makes it possible to have your
images immediately and transfer them to a computer. The Canon T3i can take both
still pictures and videos – and it does a great job of both!
How the Camera Works
At its most basic level, a camera works very much like our
own eyes – it captures light and converts that light into information. A camera
has three different settings or functions that affect how light is captured.
Aperture controls how open or closed the lens is. Shutter
speed controls how slowly or quickly a picture is taken. ISO controls how
sensitive the camera is to light. For more information on these settings, go to

To use the T3i, you need to first turn on the camera. The
On/Off switch is found on the top of the camera.

How to Take a Picture
Now that you are familiar with the modes of the camera, you
can take a basic picture. I would recommend keeping the camera on the Auto
setting for now, which is the green A on the control circle.
To take a picture, you need to look through the viewfinder,
frame your shot, and press the round black button on the top of the camera near
the front right. You should hear a “click” or a “snap”. This is a good way to
make sure everything with your camera is working.
How to Record a Video
On the T3i, video has its own mode on the camera. Turn the
dial to the icon that looks like a little camera on a tripod.
On other cameras the setting might be elsewhere, so look for
the camera icon to find the movie setting. Once you have switched to movie
mode, the screen on the back of the camera should turn on and show you what the
camera is seeing. This is called Live View and will let you see what your
camera is seeing without having to hold the camera up to your eye.
You should then see a red dot on the screen – this means you
are recording! Press the button again to stop recording.
You can review any pictures or videos you have recorded by
pressing the “Play” button near the bottom right of the back of the camera (see picture to the right).
Putting Your Footage
on the Computer
Once you have recorded all of the videos that you need to,
you will put them on a computer. If you have ever done this with another
camera, it works exactly the same way.
On a mac, you will insert the memory card into the memory card slot on
the computer and an icon that looks like your memory card will appear on the
desktop. Double-click the icon to open
up the memory card. You will need to look through the folders on the card to
find your videos. Once you have found them, you will need to select all of the
ones you want to keep. You can select multiple videos at once by holding down
the “command” button and clicking each video. Once you have them selected,
click and drag them to the desktop. I recommend putting them in a folder with
your name on it so it is easy to find.
Now you are ready to edit your clips together!
