Switch the camera on
Set the aperture ring on the lens to A position; which lens is it, by the way?
Press Fn followed by the right arrow on the fourway controller; use up or down and select ISO 200 or 400; press OK. This is just to get a predefined setup.
Set the mode dial to Av; turning the e-dial (scroll wheel) will change the aperture and you can see that in the top display as well as in the viewfinder (underlined number). The camera will keep the aperture constant and vary the shutter speed depending on the light. Aim at something dark and press the shutter halfway; the shutter speed will be slow (e.g. 1/30s, 30 in the viewfinder), aim at something bright and it will be fast (e.g. 1/1000s,1000 in the viewfinder).
Set the mode dial to Tv; turning the e-dial will change the shutter speed and you can see that in the top display as well as in the viewfinder (underlined number); the camera will keep this shutter speed constant and will vary the aperture depending on the light; again aim at something dark and something light.
If you have a manual focus lens, focus till the green hexagon lights up; next press the shutter button halfway, wait for the hand symbol (if you have SR on) and fully press the shutter to take the photo. For an autofocus lens, just press the shutter halfway to start the focusing process, wait till the green hexagon lights up and the hand symbol shows and fully press the shutter button to take the photo.
If something does not go according to above description, let us know.

That's the digital preview and it does NOT take a photo
You have to use the shutter release button.
