I took this picture of Vernazza at night on October 5th, 2018, with a Canon EOS 5D Mark IV and the Canon lens: EF 24-105mm f/4L IS II USM, during the so-called "blue hour".
I developed the image in Photoshop CC and then edited the color using the Nikfilter Viveza 2.
The image is based on the following technical data:
Focal length: 35mm
Aperture: ƒ/7.1
Exposure time: 4 seconds
ISO: ISO 200
