RE: Advice On Dark/Underexposed Pictures

You don't say what camera, but I'll assume it has an option of displaying a histogram of the image. Learn how to read this, and use it to adjust your settings to suit the conditions. All metering systems can be fooled, and they also vary from camera to camera. The histogram tells you what has been r...
