hi,

do you guys set rear curtain for macro shooting (insects)? :dunno:

correct me if im wrong, by setting rear curtain for the flash, it actually brighten up the background.

usually i set my shutter to around 1/60 with rear curtain setting, but the background is 90% dark although the lighting on the object is just nice. :what:


question.
1. wrong setting for my shutter speed that causes rear curtain unble to work properly?
2. should not use rear curtain unless it is dark?

do share yr views and correct me. thanks.

btw im using d700 with sb800.

the only difference of rear curtain sync to standard flash is that the flash is fired at the end of the exposure
this is good for long exposures and movement.

google it for more info.

One issue....

with Nikon's CLS system, the flash will fire a pre-flash at the subject and at macro distances, you may see a double image esp when the insect moves slightly due to the pre-flash.

rear curtain sync is flash fire just before the shutter closed, it is not to light the background at the rear.

if your exposure is at 1/60 and the background is dark, simply tell you that the shutter speed is too high to record the background with the ambient light.

at 1/60, flash fire at front or rear does not really make much different, since the background is so dark and your subject is stationary

Like what Mr Ortega said, rear curtain sync good for long exposures and with movement.
you can see the effect of rear curtain sync is when you able to record your subject in motion with ambient light, and the flash freeze the subject movement at the final moment.
