Does this means the ppl in foreground can relax until 2-3 sec before the shuttle close then keep very still and smile.
I got them to be still for 20secs…no wonder so blurrrr besides it was freezing -38*C
Thank you - great advice.
Hi no flash.. only long exposure
I hope you get the suggestion right.
What sis Shizuma suggested is use flash for this.
But photographers must also understand rear sync flash is not a magic pill.
Yes, flash light is able to freeze the image due to high intensity light emit during a very short duration, like 1/500s and shorter, but if the exposure time is long enough (slow sync) for the existing light to record images of your subject, and if your subject moved, it will create double images, or what we call "ghost image".
the camera default setting for slow sync is front curtain sync, means flash is fired once the shutter open. so the images recorded by existing light is after flash is fire, any subject moved during the whole exposure will create double image.
but when photographers use rear curtain sync in long shutter speed, the flash is fired just before shutter close. so the double images is still record but is before the sharp images.
read this page you will get a better idea of front and rear curtain sync.

From your post respond to v0857, it seem you miss the part of using flash, so if you use long shutter speed without flash, and your human subject moved during the whole exposure time, they will still be blur.
and if you use flash, you want to record sharp image of your human subjects and not ghost images, you have to ask your human subjects to keep still thru out the whole exposure time, regardless front or rear curtain sync.
I remember some time ago, one member want to shoot portrait at night with city skyline as background. he came out a clever idea to record sharp images of model during long exposure.
He set up tripod to compost the shot and pose his subject, use flash in long exposure to record his human subject, and he ask his subject to walk out the frame once the flash fired. the shutter is still open and record the beautiful night scene.
so guess what he got, a semi-transparent model standing in front of skyline night scene.
Ghost in front of MBS.............. LOL
if possible in future you should shoot wirh rear curtain flash. or use an external flashgun and hold the remote trigger in your hand and flash manually over a long exposure
Beautiful capture of the Aurora Borealis!
+1 to Shizuma on rear curtain flash, and I would like to add: tell the people to relax and only smile when you cue them. And let them know what you're doing so they won't go "how come so long?" or "ok already or not?". When it's 2-3 sec before the shutter close, tell them to smile.
I noticed that the igloo in the foreground is less sharp/defined as the 2 igloos further back. Google hyperfocal distance to know how to get both the foreground subject(the people) and background reasonably sharp.
