some shots that I took at 1/80 got blurred. Does it got to do with ISO speed? :dunno:

arikevin said:The shot that I took was at 1/80 with external flash. Could this mean the weight caused the camera to shake thus blurred image?
Hmm, okay, but my lens is 38-190mm. .Ian said:The general rule for most folks is 1 / lens focal length being the safest slow speed to shoot at. eg: 400mm lens 1/400th, 35mm lens 1/30th etc.
In time and with the correct camera holding technique (For an SLR without grip it's base of camera held cradled in left hand, right hand in front holding lens, arms locked in to your sides) and for a camera with grip hold grip in right hand, cradle under camera body and around lens with left hand or hold lens from underneath with elbow locked in to side of chest if it's a longer lens.
As well there's correct breathing techniques (always shoot when your lungs are empty) you'll find you can go a lot lower than the 1 / focal length guideline.

OzOn3 said:Well, actually it all depends on individuals.. For me, i can go hand held until about 1/50.. ISO affects the shutter speed because it is more "sensitive to light". This means that in a particular situation, your ISO speed and shutter speed, for example, is ISO 200, 1/10, and if you increase your ISO to 400, you can use a shutter speed of 1/30, i think.. Not very sure about the ISO/Shutter steps.. Maybe someone can correct me on that.. But that's the concept
aperture doesn't affect the blur images right?FOOXX said:azzuming u r uzing the same aperture n the lighting iz the same, when u double ur ISO the shutter speed will become 2 timez fazter.

This is the shot that I took at f/2.2 1/80sec ISO200 with external flash (bounced)
Ian said:In this case after a quick look at the shot you posted it's a case of the depth of focus being insufficient rather than a camera holding problem. Increase the aperture by a couple of stops, use a faster film and all should be fine.
With a 38-190 lens I'd opt for a comprimise hand holding speed based on the weight of the lens and some testing. Probably around 1/60th for an average photographer would be around the right figure for shorter focal lengths and 1/200th or 1/250th for the 190mm end.
Hmm, so not shaky problem?Zerstorer said:arikevin, this shot looks out of focus to me.
arikevin said:Ian, my camera is not dSLR.
Btw, does aperture affects the distance? or does the distance affects the aperture setting? :dunno:
Well, I thought so initially but I believe your theory. Quite true. However, there is another photo that I want to show you about my question in the first place.
This photo 1/40sec, f/2.4 ISO 100
Thanks for the explanation.dkw said:Ari,
using large apertures decreases the 'depth of field' (DOF) of the picture. That is, parts of the picture that are closer or further than the point of focus will be very 'out-of-focus' (OOF). That could well be the case for the first picture you posted. Just looking casually, it appears that the little girl's face and ears are quite in focus, whilst the milk carton and the man's ear, which are nearer to the cam, are OOF. In order to increase DOF, so that more of the picture is in focus, you need to decrease the aperture size (stop-down). Generally f/8 onwards will give sufficiently decent DOF that most of the picture will be in acceptable focus. However, in low-light shooting, you may not have that option. So yes, aperture does cause blurriness.
The second pic is possibly hand-shake. What focal length are you shooting, 1/40 may not be fast enough.
