If you’re shooting in manual mode but you still find yourself wrestling with your camera automatically changing the exposure, you need to check your ISO setting. If it’s still on auto, you’ve found the problem.
Auto ISO is a fabulous invention – if you are using auto exposure modes. What it does is adjust the ISO, shot by shot, to maintain a minimum ‘safe’ shutter speed to prevent camera shake even in really low light. You can specify the maximum ISO you want the camera to go to, and the minimum shutter speed you want it to use. It’s brilliant.
