Programmed Auto Mode Underexposed | FujiFilm FinePix E550 instruction

Program Auto (P), your night pictures always come out too dark. They are simply underexposed. But, why is that -- if your camera's shutter speed ranges from, say 10 sec. to 1/2,000 sec.?

Go back to your camera's User's Manual and look a bit more carefully. Are all the shutter speeds available in Auto or P mode? Ah-ha, many digital cameras (we're talking consumer models here) do not make the whole shutter speed range available in A and P mode! Perhaps the slowest shutter speed available in A and P mode is only as slow as 1/3 sec. That's usually not long enough for night photography. To access the longer shutter speeds, you may need to select one of the other shooting modes, e.g. Shutter-Priority, or even switch to full Manual mode.

So ensure that your digital camera has full Manual mode and allows access to the full range of slow shutter speeds in that mode.

Self-Timer & Remote Controller

Another feature that you want your digital camera to have is a self-timer or, ideally, a remote controller. The purpose is to allow you to depress the shutter release button without introducing camera shake. I particularly like the remote controller, but not every camera comes with one or even has one available optionally.

But almost all, if not all, cameras has a self-timer. Usually the self-timer counts down from 10 sec. I find that a bit long to wait, especially since you would need to take more than one shot and it's minus 10 with the wind chill outside. The cameras that additionally provide a 2 sec. self-timer have my nod of approval here.

Tripod

A mandatory accessory that you need is a sturdy tripod. When you let the shutter stay open for a long time, the camera needs to be kept rock steady, otherwise you end up with blurred images.

Examples

OK, so we have our digital camera and tripod, and are ready to venture forth into the night in search of interesting night shots. When we find one, we set up camera and tripod, frame and... what do we do now?

Well, the images below show what happens when you take the same shot using P mode, then in Manual mode with various different shutter speed/aperture combinations, all in search of the correct exposure. The camera was on a tripod for all three shots.

Programmed Auto Mode – Underexposed

Fujifilm FinePix E550

7.2mm, Programmed Auto, Pattern

Shutter Speed 1/4 sec., Aperture F2.8, ISO 80

In the above example, the camera uses the slowest shutter speed and largest aperture available in P mode and at the widest focal length. The picture is underexposed.
