DO NOT BE AFRAID TO UNDEREXPOSE YOUR SHOT
In certain scenarios, you’ll want to shoot an underexposed long exposure image. For example, to capture the colors splashed across the sky during sunrise/ sunset, and the cloud movement. This method allows you to get that dramatic effect and mood, without losing any details in the foreground, even though the original image may look close to pitch black. This is very important as the sky may be completely blown out, or overexposed beyond recovery if you expose the image normally.
