Dawn. Great light. Maybe!? The right moment? Can my camera capture the moment as I see it? All good observations and questions.
Ok! The camera has trouble focusing upon clouds. No contrasting lines help to define a focus point. Set the focus point on the trees or something at the horizon. Exposure. The scene is dark and the meter tends toward overexposure. Metter the sky to increase the saturation of the morning color. Finally, cheat. Use Lightroom to increase vibrance and saturation. It might just look like what you saw at the critical moment.
