Was having difficulties with the top left of the frame, in full size format it looks spectacular, in web, it's struggling with what appears slightly blown highlights. I blended in a little cross processing and came out with this. I think it's good enough.
Twilight will always be my favorite light of the day. This is the time of the day when magical and almost surreal things can happen. Often times it's extremely subtle to the naked eye. Sometime the eye can't see what's happening, but the camera's sensor has gathered more light, and there is a glow of color that could not be seen by the naked eye. This is frequently the case with faint Aurora's in the far North or South.
This is another case of this. This is the first light of the day reflecting faintly off clouds onto the mountains you see. A few frames after this the traditional alpine glow of the sun actually hitting the mountain with orange hues can be seen, it's bright, and quite distracting. I liked this faint glow and the evenly distributed illumination.
Frequently alpine glow in the Himalayan mountains only touches the tips of the mountain tops. There are such large mountains surrounding each other, that by the time the light penetrates, it's already quite high in the sky. Only the tips of the 8,000+ meter peaks typically get illuminated. But during twilight often you can get an even illumination, with some glow, and a fairly even dynamic range to work with.
