How to Capture the Perfect Blue Background in Wide Angle Photographs

Perfect Blue Backgrounds

Getting the perfect blue background on wide-angle photographs is one of the keys to a successful image. Although many folks are daunted by the task, learning how to do it consistently is very easy! The key to achieving a rich blue background is by understanding how to use the cameras “light meter”. Here are a few steps to get you started in the right direction.


  1. The first step is to set your f-stop based on how far you are from your subject. The further you are away from your subject the more open your f-stop should be.
  2. Aim your camera at the blue in the direction you are planning to shoot (make sure you aim at the unencumbered blue background, not the foreground).
  3. Keep an eye on your light meter in the view finder while adjusting your shutter speed until the light meter reads between 0 and – 1. Voila! You are now set at the speed you will need to achieve a rich blue background.
  4. Take the photo.
  5. Review and adjust – Have a look at the image, is the blue too light? Time to increase the shutter speed. Blue too dark? Slow the shutter speed down.


That’s it! A quick and easy way to get the perfect blue on your wide angle underwater photographs.
