Photography Question 

Stacey A. Hurley
 

Timed Exposure = Blank pictures


I have a new Canon 5D (digital SLR). I was asked to photograph a security vehicle with lights flashing for a timed exposure. The time was dusk, overcast, with a grey truck and a guard standing next to the vehicle. Shooting info: Mode - Bulb, Shutter Speed 1, f/11, ISO 100, focal length 56mm, cloudy setting. I used a tripod weighted down for stability and a remote shutter release. My photo came out white. What did I do wrong?

  Probably just super over exposed it.

  With a digital camera in this instance; I'd probably take TWO photos..(on a tripod of course) and combine then.

  I agree with Gregory. I'm not an expert ( Far from it). If you do not want to combine images, you could bracket your exposures and shoot in RAW then you have the latitude to change your exposure even further in your choice of Raw editing programs,You will also have the benefit of being able to change you WB if needed. Even PSE4 can process RAW files,just not as much as CS2. - Mike

  You can shoot it once without going thru all that.

  If it was still daylight out, why would you want to shoot in bulb mode?
If you have an auxillary flash, I would meter for the truck at a slow shutter speed, then adjust your flash output for whatever aperature you metered the truck out.
The flash will better illuminate the guard and the vehicle while at the same time, the longer shutter speed should capture the flashing lights.
Use your LCD viewer to judge the results and adjust your camera/flash settings accordingly.
