The sunset was having a dull colors and a thick cloud on the right side. Decided and tell my friend to wait for the twilight, then the expected colors came out and the thick clouds slowly gone. Take a long exposure for 120-seconds to capture the movement of the clouds.

I shoot this image using my Canon EOS-1Ds Mark III plus Canon 16-35f2.8L Mark II lens with a Lee Filter GND attached. Other gears used is Manfrotto tripod and Phottix Aion wireless intervalometer. Settings used is Aperture: f11, 120-seconds exposure, ISO: 250 and focal length of 16mm.
