I received a number of emails on my photo that I used in a composition post. People wanted to know how I took that photo at night, specifically, how i achieved proper exposure and had the narrow beam of blue light.
So, I thought I would explain how I took this photo in more detail and discuss the camera settings.
Here were the settings and gear used.
Camera: Nikon D3 set to aperture priority.
Lens: Sigma 24-105mm f4
Focal Length: 28mm
Tripod and head: Manfrotto 057C4 Tripod – MT057C4 and the 057 Magnesium Ball Head with Q5 Quick Release
Accessories: Nikon wired remote control
Location: standing on the back of the Musee national de la Marine. That is where that statue is. It is off the Espl du Trocadero. You have to step up and position yourself against the back of the building where the columns are.
Aperture: f4 focused on the Eiffel tower. I tried to take the photo with the statue in focus, but the depth of field really did not work because i wanted the tower to be the focal point, and sharp.
Shutter Speed: 1/6th of a second to achieve the beam of light that was fairly straight and not elongated due to a long exposure
Exposure Compensation: Was set to + 1/3 to try and bring as much detail in the shadows of the statue as possible. I didn't want harsh contrast and a silhouette.
ISO: 2500 to allow proper exposure and a faster shutter speed at such low light.
When I got the photo into the computer, there was digital noise. I ran it through NIK define and it eliminated a lot of the digital noise. In camera raw I darkened the sky and sharpened the lights on the Eiffel tower.
Then I cropped the photo a bit and it was complete after 5 minutes of editing.
I hope that better helps explain the process to achieve this photo.
