need a help

[aneeshvmohan]

i am using Canon Powershot SX 10IS.. when i take snap in shutter speed priority mode..even if i set the shutter speed to 1/3000 i couldn't get photos of fast moving objects still...what to do?what will be the problem?. But shutter speed is working in manual mode

please give suggetions

If you post an example shot it will be a lot easier to help. 1/3000 should be more than enough to freeze any movement* so something else must be going wrong.

*Some stuff moves this fast such as bees wings etc but not a lot.

Here's your EXIF

Model: Canon PowerShot SX10 IS
ISO: 80
Exposure: 1/5 sec
Aperture: 2.8
Focal Length: 5mm
Flash Used: No

It says your shutter speed was 1/5 sec. It probably did that to compensate because you weren't using a flash but I'm not familiar with that camera model.

actually i set the shutter speed 1/3200
Tv mode works only with flash........with flash i can even get a still image of moving object by setting shutter speed to 1s

Well the picture was definately taken an 1/5 sec. The EXIF doesn't lie and the fan is blured like it was shot at that speed. Either you aren't setting the shutter speed correctly or the camera is somehow overiding your settings to expose as it sees fit (I would doubt this though).

Ignore the flash in this context as shutter speed will not perform as expected when using a flash.

shutter speed is working in manual mode but i think its not workin in Tv mode.. why????/

It appears the fastest shutter speeds in TV mode can only be used with smaller apertures (from Google)

Therefore what is probably happening is that the camera realises that it can't use 1/3200 at a large enough aperture to expose properly so it overrides the setting. For example based on the shot above the difference between 1/5 and 1/3200 is 10 1/3 stops. Therefore to expose correctly your camera would need to increase the ISO and use a larger aperture to compensate. Apertures simply don't get that large so your camera chose to ignore your setting.

If you tried the same photo in manual it would simply be black.

Look at page 101 of your manual. You have setting that's called "Safety Shift", & as it says on page 101, when in Tv or Av mode the shutter speed & aperture will be automatically adjusted when correct exposure cannot otherwise be obtained.
