Shooting HDR sets if you don’t have an AEB (Automatic Exposure Bracketing) setting on your camera

Not every camera has an AEB (Automatic Exposure Bracketing) setting. Here’s the technique that I was using before I realized that my camera’s had an AEB setting…

You can still capture bracketed photos with any camera that has an Av (Aperture Priority), Tv (Exposure Priority), or Manual mode, and with a very small amount of practice, you can get it pretty quickly.

Here’s how to collect your set of three shots with no AEB setting:

  1. Put the Camera into AV mode
  2. Put the aperture setting somewhere in the middle (4-5.6 range)
  3. Press the shutter or shoot a shot to see what the settings are that the camera chooses for you.
  4. You will use this information to adjust your aperture in preparation for the shot.

Here’s how: Your two constraints are:

      1.  You want your slowest shutter time (brightest picture) to be no slower than 1/60th  of a second
      2.  You don’t want to run out of contrast when you have a very fast shutter speed at the limit of the camera (meaning you want a shutter speed slower than 1/1000 or 1/1600).

The adjustment is pretty easy, with a couple of rules of thumb:

      – Start with the aperture at f4.0. Shoot a test photo, or get the camera to display the settings for you (the images in the manual are too small to see whether the appropriate info displays as you shoot. If not, go into playback mode, and hit the “disp” button).
      – If the shooting time is faster than 1/400, then move your aperture to f5.6
      – If the shooting time is slower than 1/240th, move your aperture to f3.2
  • NOTE: these are my guesstimates – after you’ve shot a few “brackets”, you will get a feel for what 3 bracketed photos look like, and you can adjust manually…
      • – With the new aperture setting, shoot a test photo, or get the camera to display the settings for you.
        – You now have the info you need to take the photo. Switch into “manual” mode, and set the aperture to the number you decided upon. You will not touch aperture again for this series of shots
        – Set your timing to be (approximately) 4x as fast as the speed the camera “suggested” and displayed. i.e. if it suggested 1/200th, set it for 1/800th. If it suggested 1/250th, set it for 1/1000th.
        – Frame your photo, lining up landmarks so that you know your approximate framing. Take your first shot
        – Adjust the timing to be the suggested timing. Re-frame to line up your landmarks. Take your second shot.
        – Adjust your timing to be (approximately) ¼ the speed the camera suggested. If it suggest 1/250th, set it for 1/60th. If it suggested 1/400th, set it for 1/100th. Frame your photo, lining up landmarks so that you know your approximate framing. Take your final shot

    You now have your 3 photos (plus possibly 1 or 2 “junk” photos). Now’s when you get to use PSP to have
    some fun with them.
