Thread: Iso

    I also shoot as low ISO as possible if the conditions permit. Less grain is always easier to work with...unless you want special effects like grainy black and white photos that give the magic touch...there are films that are ASA3200...I think Kodak TMAX...

    Talk about grainy...

    For low light situations, i would jack up the ISO settings of my camera to try and increase the shutter speed so as to reduce hand shake...also, when working with zooms, sometimes i would have to increase the shutter speed to again, reduce handshake.

    My general guideline is to use as low an ISO as possible. If you find the photo blur from handshake or the subject is moving, use a higher ISO. Make sure that you will be comfortable (ie. hand-holdable) with the shutter speed of the camera at the particular ISO.

    Generally,

    lower ISO (50-200) for stationary subjects (eg. landscape, night scenes, macro work with flash)

    higher ISO (400 onwards) for moving subjects (mainly indoor shoots eg. concerts with ISO 400 with flash, 800 onwards without flash)

    if you are using digital, beware of electronic noise at higher ISO. If your camera has noise reduction, switch it on.
    thanks!! you've been of immense help! so basically use a low iso as possible, as long as there's no blurring? on a digital cam pov, wat would be the recommended iso for normal outdoor shooting in both sunny and cloudy conditions?

    here's a shot taken during cloudy weather(about to rain), any suggestions on how i might improve the shot? seems kinda blur to me... pictures taken using my canon ixus 330 in manual mode(exp compensation +1/3, iso 50, white balance cloudy, flash off)


    here's another one taken with the same settings as above

    the first pic seems sharp on the left side. may be u focus on the left side only

    Another rule of thumb...always use the reciprocal of the focal length you are shooting for a guide as to what the shutter speed shld be...for eg:

    shooting at 50mm, shutter speed at least 1/50s, for shooting at 200mm, shutter speed at least 1/200s...

    But most of us just usually try our luck...i sometimes shoot at 1/15s @ 200mm and hope for the best

    actually what's wrong? issit due to handshakes??

    butters,

    Provide more info like the shutter speed, aperture etc...from your EXIF info...

    actually the pics look fine...definitely shooting at least f5.6 and above...i think.

    Maybe you need to do some post processing like unsharp mask and apply a bit of contrast to help liven up the dullness due to the overcast weather.

    Butters, maybe for the first pic, next time stop down to f8 if possible...is there aperture priority mode in the Ixus 330? Use that...
