Dos and Don’ts of Photography at Weddings
This is a straightforward system I read about a considerable time back, and it works very well. It’s used by me a lot when shooting weddings and portraits.
Out of doors portraits can frequently finish up with a washed-out and uninteresting sky when you set your camera to properly show the person’s face.
But if you set the exposure to capture the sky completely, you finish up with a really dark or silhouetted person. Everyone knows you may use fill flash out of doors to correct this, but even then the exposure could be a bit unpredictable if left up to the camera. The system I love to use is : take a meter reading from the sky set your camera to Manual mode set the aperture according to the depth of field you desire set your shutter speed to properly reveal the sky ( based on the earlier reading ) turn your flash on and set it to E-TTL ( or whatever the equivalent is on non-Canon cameras ).
