    Question Images not sharp

    Hi,
    I'm a newbie in photography and need to ask some questions.

    At 90mm (focal length) 1/320 f8 ISO-800, I shoot a person (moving towards me) under shade. (His back is facing the brighter area). However, I fail to get a sharp image.

    When i first saw the pic, i tot it was shot at low shutter speed, but 1/320 for 90mm focal length is fast enough, right? Shooting at F8 using a canon 28-105mm USM should be good enough right? And will ISO affect the sharpness (maybe due to noise reduction, losing of details) ? Or my hand is shaking? (Or combine jerky hands + moving subject, 1/320 for 90mm may not be enough?)

    Please advise, me kinda disturbed Thanks

    probably your friend is moving too much or OOF. you might wanna use a fill flash (pop up flash on ur 400D) for such picture. his face appears to be very underexposed. noise in an underexpose area makes it more obvious, u can also get some noise freeware to reduce the noise.

    I see. So it's not the settings of the shoot right? Okay
    YEah, I heard of fill flash, but still not use to shooting flash in broad daylight.

    As for the noise freeware, is it a firmware or another photoshop-like program to edit?
    Anyway, it's alright, as long as I use "sharpen" tool, it will do good.
    Thanks

    if u keep ur hands steady, settings is ok, subject not moving, no problem. yeah do try fill flash if in such setting again.

    can be a CS2 plugin or a program itself.

    Seems to me that his shirt is more "focused" / sharp than the face....
    Did he put his face forward?

    Maybe the subject has moved after you have locked focus and before the shutter was released. I don't know if Canon has predictive focusing which tracks the subject movement to predict the focus at the moment the shutter is released.

    Yes its called AI servo but on consumer cmaeras it might not be fast enough to to prediction. Normally for shots like these I end up shooting in 2-3 shot bursts toget 1 thats in focus..

    Did your camera manage to lock focus in the first place or did it just shoot? The side of the face does look oof but can't confirm the front of the face since a little under exposed. How fast was your friend walking? like lsisaxon said, he could have moved out of focus just before you released the shutter.
