Excellent. I take photos in churches all the time and always get images like the 1st photo in the second example. I'm going to try rear curtain sync the next time I'm out in a church or large space.

Do you need to shoot using a tripod for this to work to avoid blur from camera movement. ??

Doug Steakley

I strongly suggest using a tripod when using rear curtain sync flashand here are the reasons: unlike ordinary flash which "freezes" the action and blacks out the background, rear curtain sync flash fires at the end of the exposure instead of at the beginning. So the image sensor is gathering light and information while the shutter is open and to have the image be in focus from front to back I recommend a narrow aperture--say f/14-f/18. This narrow aperture will lengthen the shutter speed making for a longer exposure and camera shake or blur is inevitable without a stable platform such as a tripod.


We do not at all times get our hopes and dreams, and we never generally get our very own way.There's an interesting gendering to that commercial, too. Men as soldiers, women as child care providers or as children. The latter is where the game language comes in.

I thought it was enjoyable at best.*
