I know this sounds dumb but let's say out of 20 pics I take, about 8 or 10 of them come out blurred while the rest are in focus, how do I know whether it was due to handshakes/vibration or the fact that the subject was moving?
I mean if you are taking a photo of a person & he stands still to pose for you, then I would ASSUME that a blurred photo means shakes/vibration. Can't be that he's moving 'cos he's frozen there for you!
But if the ppl are moving e.g. models walking on a stage or performers doing their stuff outside Ngee Ann City. Then how do I know if a blurred photo is due to shakes/vibration or the fact that the subject was in motion? If I'm not wrong, when your subject is in motion (esp when they're fast e.g. a dancer on stage) it results in blurred photos.
Just wanna know how I can differentiate when a blur was caused by this & when it was caused by that. Thanks!
