Take Pictures With Low Ambient Light

All I can say is taking pictures with low ambient light is fun. It gives a whole different feeling then the day and night. I personally like the grey bluish view just after sunset and before the earth is totally consume by darkness.

And to help you get that new feeling, you just decrease the aperture, increase the ISO so that the camera is more sensitive to light. Then, you will want to increase the exposure time but slow down the shutter speed. All this process will then help to direct more light to the image sensor and give you a good picture even the ambient light is low.

I know you some of you might be confused with what I said, so here is a quick explanation:
  • Increase ISO - increase camera sensitivity to light
  • Increase aperture - increase exposure time and light entering camera
  • Increase shutter speed - decrease light entering camera

So, Increase ISO + Increase aperture + Decrease shutter speed = More light enter the camera. I hope that is OK.

However, prolonging the exposure time make your pictures susceptible to vibration and your pictures can turn out 'shaken'. And to minimize these unsatisfactory pictures, you can either turn on the 'anti-handshake' feature in your digital camera or mount your camera on a tripod.

By the way, increasing ISO and exposure time can both introduce noise in your pictures. If the noise is unbearable, you probably will want to retake the picture or edit it with photo editing software.

As pretty as taking pictures under low light can seems, it does require more practice. One of the reasons is because this condition only last for a short time after sunset and it is easy to spoil the shot when you are unprepared for it.

Please understand this, it is common to take lousy pictures. In fact, that is how the professional photographers gone through. They took pictures and analyze what is good and what is bad with their pictures.

Just like Thomas Edison once said, "I have not failed. I've just found 10,000 ways that won't work." And you only need that one way to be good in digital photography.

Happy photographing,

Michael Wong.
