Can any of the Nikon cameras allow control of the flash during a long exposure shot?

Another question... if the CCD is larger than the actual pixel resolution of the camera, then why do images look better when reduced by 50%? (i'm speaking purely about viewing them on screen, pixel for pixel)

thanks,

Sure you can use slow sync and a speedlight for long exposures (up to 8 seconds)

Second question-sorry I do not understand....

Images look sharper on screen for the same reason they may look great on a 4 x 6 print than on an 8 x 10. You have compressed the size of the image-and therefore detail density is greater-and you don't detect "missing" information (i.e. lack of detail as you enlarge).

still no answer on the long exposure with flash.. (am i missing the terminology for it?)...

as to the reason why a x-megapixel CCD does not produce a perfect x-megapixel image (just a x/4 megapixel image) is that each sensor on the CCD is only capable of sensing R, G or B... so that although there may be 1280x960 sensors, there really is only a 640x480 image...

gotta run,

Ryan -

"Slow sync" is a setting on the camera that tells it to use a slow shutter speed in conjunction with the flash setting. Did you instead mean to ask whether you can choose when (at what time) the flash goes off during the long exposure? The 990 does have two flash sync modes, corresponding to the conventional "front curtain" (flash at beginning of shutter-open time) and "rear curtain" (flash at end of shutter-open time) settings. - Did this help, or did we still miss your question?
