It's a bit difficult to give tips as I don't know exactly what I'm looking at and also not what was possible in the situation.
First of all, I like the idea and the pose of your model is cool. It would be nice when she would have been a bit more inside the tunnel (but I don't know if that was possible).
If you would have chosen a different background color or a different color for the outfit, your model would stand out a bit more. But again; I don't know if that was possible in your situation.
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.
Thank you for sharing your process.
Everyone uses their own method and always learns from each other.
Exactly!
