One great benefit of having some interest in the sky during sunrise or sunset is the opportunity to photograph a scene at different times, and be able to come away with more than one acceptable image.
On this particular morning, there was very nice cloud cover above Lake Tahoe. Hoping to make the best of the situation, I set up to photograph not only at sunrise, but also just before and after sunrise. I also used different filter techniques to photograph each moment, so I could capture multiple effects. For this image I used a 10-stop ND filter, to show the effect of streaking pre-sunrise clouds above Emerald Bay. When shooting in the direction of the sun, I like to use a long exposure to obtain this streaking cloud effect just before sunrise and also after sunset, through twilight.
Carefully check the first couple of exposures in the camera’s viewfinder. If you notice blown-out highlights in the sky you will have to adjust the in-camera exposure. Another option is to attach a neutral density grad filter to your Big Stopper filter. This will eliminate blown-out highlights,
