tip for using flash compensation to improve your wedding dance images
Receptions are so fun right? I love capturing everybody on the dance floor cutting IT UP! But do you find that most of your images shot with flash (when it is set to ETTL mode) -- tend to be underexposed? This is the biggest mistake I see photographers making when it comes to using flash.

During a conversation with one of my second shooters at a recent wedding, I found out that she was struggling with under-exposing her images, and that she had never heard of the simple trick I'm going to share today to fix the issue once and for all. I figured this might be something that is not widely known among photographers. I can't wait to help you master your exposure throughout a wedding reception!

The reason it is so easy and common to underexpose when using flash during wedding receptions is that most images taken at a reception have some type of ambient or constant lighting - whether it's candles, wall lights, ceiling lights or twinkle lights - in the background. Note the magenta up-lights in the background of this shot:

And the twinkle lights in the background of this one:

When your on-camera flash is set to ETTL mode, your camera evaluates how much flash power should be put out and includes these lights in the equation. So in trying to accurately expose for the ambient lights in the shot, your flash under-exposes your subjects. This scenario is much like shooting a subject in a room with window light behind them. You need to tell your camera to over-expose in order to PROPERLY expose your subject. In the case of our reception scenario, you need to ask your flash to put out more power than your camera thinks is needed.

Flash compensation is the setting you use to ask your flash to over-expose. As each camera is different, look for this symbol on the top of your camera:

On the Canon 5D Mark III the button used to access the flash compensation settings is shared by the ISO setting:

Once you find that button, push it and then try both of your wheels to determine which is used to control your flash compensation. Look for a meter like this on the top of your camera:

This meter is just like the one in your viewfinder except that it is used to over or under-expose your flash when it is on your camera and in ETTL mode. So you'll want to move the little arrow to the right of the middle of the meter to tell your flash to put out additional light.

Because I am always dealing with ambient lights in my reception shots, I tend to leave my flash compensation setting on +2/3 or +1 full stop for the entire reception. But I check my LCD screen (and sometimes the histogram) to see if I need to make adjustments.

Yay for saying good-bye to under-exposed reception images!!
