RE: Ask the photographers!

My bad, I forgot to give infos @friendlymoose.

Here are the specs : 85s 16mm f/5.6 100 ISO
This picture is a lightpainting picture created in real time, captured to the camera in one single photographic frame. I do not edit my pictures (No layers /no Photoshop / no editing except minor adjustments (lens correction profite, WB, contrast (+12)) and addition of my logo.)

I made this picture at a pedestrian bridge. This is one of my kinetic approaches in lightpainting : I mean I use lights in the environment and I make my camera rotate on its axis using a "camera rotation tool". I cap/uncap the lens to capture only what I want to. This technique can look to be a "lazy" approach of lightpainting but it's trickier than it seems, especially when you want to place someone into that composition.

Here is the process : I first used a flashgun to lit Amelia, then I capped the lens and she left the frame. After that, I uncapped the lens and I started to do my job (capping and uncapping the lens while rotating the camera and pulling the zoom). When I felt I made enough, I ended the long exposure.

As I told to @cryptoreforma, a light-blue backlight would have been great but I wasn't able to do it on the moment.
