For anyone with knowledge of an SL1, am I doing the exposures right? In go to M mode and go to exposure. When I turn the dial I get my two lines going left and right. So it turns out like -1/+1 or -2/+2. I can't seem to just change it to +1 or +2.
Instruction manual was useless.
I have an SL1. Exposure Compensation doesn't work in Manual mode because you are already manually setting the exposure parameters. As a general matter, Exposure compensation is used in the automatic or semi-automatic modes to adjust from the factory-set 18% gray that the camera will use. In your snow setting (and in beach settings), the scene is bright, so the camera wants to reduce the exposure to preset 18% gray. You have to override that setting with Exposure Compensation (EC) and adjust the exposure back up.
When I use my SL1, I set the Mode Dial to Av mode. Pick an aperture setting like f/8 to start, and set your camera to ISO 400. The camera will choose a fast shutter speed by itself. Look through the viewfinder, compose the scene, focus on the subject, and press the shutter button halfway to activate the meter. While the meter is active, with your thumb press and hold the "Av+/-" button that is to the right of the LCD screen while at the same time using your index finger to rotate the Main Dial to adjust the exposure up or down. In the viewfinder you will see the exposure meter move to the + side or - side. For your snow scene, try +1 stop. Take the picture and see how it looks. If you need more compensation, add another 1/2 stop.
Also: The EC adjustment will remain until you change it back. So don't forget to reset this after you've used it!!
Edit: This is all explained in the manual on page 123 under Setting Exposure Compensation.
