On-Camera Flash

The on-camera flash (the flash that's built into your camera) is on the top of the camera body and it sends a flash of light forward about 10 feet from the camera.

It's the perfect tool for lighting up dark subjects, right? It'll expose the image perfectly because light is light and as long as you get it into your photo, it'll all be good. No. No. No.
On-camera flash is just about the worst possible thing you could choose to do to light up a dark image.
The built in flash is a very harsh light that sends hard shadows into your photo. It creates red eyes, an unprofessional feeling, and doesn't send the light far enough to evenly light your photograph. It can also create an ugly shadow from your camera's lens.
Take a look at these two images. Try and guess which one used the flash.













Yeah, it's not that hard to tell the difference, is it? The flash may light up the subject and separate it from the background, but it does so using a very unflattering light.
If you need more light in your image here are a few solutions that don't include a damaging on-camera flash:


  • Set your camera to a longer exposure. Watch out for unwanted motion with this one. If your subject moves, it could become blurry.
  • Use an external flash. Either on the hot-shoe or off camera in slave mode. Most external flashes will provide much better results than the built in flash.
  • Bump up your ISO a bit. Careful, though! ISO is a dangerous option to mess with when you start getting above 400. You wouldn't want too much noise in your image.
  • Open your aperture. But keep in mind that the wider your aperture gets, the shallower you're depth of field becomes.
