Finally painting with light!!! LOL. Yes, had my camera set up on a tripod, with no light, the only light was from the torchlight.
I did a couple of shots to understand the correct setting and apparently a larger aperture (F11 & above) is the key to capturing this the way i intended. Photo taken at smaller aperture (f3.5~f8) allow too much light into the camera and tend to let the camera capture more of the surrounding. Since I prefer a darker surrounding, adjusting the aperture to minimum is the answer.
If you look carefully, you can see my face in the middle. The word I was trying to write is “I Lov U’
Taken using my Nikon D5000 18-55mm f3.5-5.6
