This is one of the images, I made late last night. The sun had completely set and we just had the glow of downtown Cincinnati in the background. I lit our bride with my high powered flashlight. This is becoming one of my favorite lighting techniques these days - and we got this terrific result. Again, since the camera needed to be set to 2800 degrees Kelvin to balance with the flashlight, I got these very cool (no pun intended) blue tonalities throughout the image. I think the background, colors, and expression combined resulting in a quite dramatic image.
Camera specs; Canon 40D fitted with 70-200mm IS lens at 70mm, F 4.0 @ 1/6 second - handheld, ISO 800.
