I’m new to the Canon EOS 550D and trying to use Manual (M) mode. I expected to be able to change the exposure level directly, but I can’t find a control for it. How do you change exposure in Manual mode, and which camera controls adjust shutter speed, aperture, and ISO?

Based on experience, I am certain you are confusing exposure and exposure-compensation.
Exposure is a product of 3 parameters: ISO, shutter-speed, aperture. In Manual mode, you control all of these and doing so sets the exposure. @jrista shows very clearly how to control each of them. For how they relate, see What is the exposure triangle?.
Exposure-compensation (EC), marked on most cameras including yours by a ± sign, is an offset from the exposure the camera is computing in automatic (P, Auto) and semi automatic mode (S, A). In all these modes, the camera computes an exposure (based on the metering mode) and EC is how you tell the camera to adjust the computed value by a certain amount.
In other words:
- In all modes except manual: The camera computes an exposure and you use EC to tell it to make things brighter or darker relative to its guess.
- In manual mode: You set the exposure exactly using Aperture, Shutter-Speed and ISO. There is no offset the camera can apply because all the parameters have been fixed by you.

Generated from our catalog & community — verify before relying on it.
In Manual mode, there is no separate exposure-compensation control. You set exposure yourself by changing the three exposure variables: shutter speed, aperture, and ISO.
On the Canon EOS 550D:
- Turn the main dial near the shutter button to change shutter speed.
- To change aperture, press and hold the Av (+/-) button on the back while turning the main dial.
- ISO is adjusted separately using the camera’s ISO control.
The meter in the viewfinder/screen can still show whether your current settings are under- or overexposed, but in M mode the camera does not automatically apply exposure compensation the way it does in Auto, P, Av, or Tv modes.
So if you want a brighter or darker image in Manual mode, adjust shutter speed, aperture, or ISO directly.
