no matter what iso speed im at my photos are very grainy...ive played around with the settings and the photos are still grainy...i could be on the same setting and take a few photos of the same thing, one out of 4 maybe ok but the rest will be grainy...very random???
i have had the camera three years now, is used quiet alot, there was something about changing something after so many shots? in the camera?

Some people report that with an ISO setting of 200 or higher, there is graininess in the pictures, so check your ISO setting. I don't own one of these cameras, but there is a lot of discussion on the net about them. The following amazon discussion about the problem deals with a fellow who upgraded to the S3 from the S1. One problem was the ISO setting got bumped up, but another problem was the ISO was increased in the Sports Mode. See if any of this applies to your situations: http://www.amazon.com/Grainy-noisy-pixelated-photos/forum/Fx36DLASC37633N/Tx2BFEA8BW518TA/1?_encoding=UTF8&asin=B000EMWBV0
There isn't enough light for that scene. 1/13th of a second is the fastest at that ISO (automatically set by camera in Basic Mode) and Aperture (auto set by camera too, in Basic Mode) that the camera can handle to provide a reasonably exposed image. Try using Tv on the Mode Dial, set a higher ISO (trade off is image noise) of around 800-1600 or even 3200 if available on your camera. Set shutter speed at 200-1000 (1/200th to 1/1000th of a second) and see if it freezes your subject. An external flashlight with hi-sync mode would help in this situation if the subject is not too far away.
The Canon A95 has been known for taking noisy and grainy photos. Try using a low ISO setting of 50 or 100 to see if that helps. Using auto ISO or ISO above 100 will put more noise/grain in your photos. Also, always shoot in the best lighting situation possible. The more light the better. You can always improve your photos with good editing software too.
I hope this helps and good luck!
When you use auto mode on most point and shoot digital cameras ( which
includes the F717) the camera software gets to choose aperature,
shutter speed, and ISO setting. When the ISO setting is used at the
faster ISOs, the images get digital 'noisy' very quickly. There is a
much higher noise level in consumer digicams at the higher ISOs,
because the sensor chip is much smaller than in the digital SLRs. F2.0
suggests yoiu are shooting at the maximum aperature of your lens and
that the light is pretty dim. If you learn to use your camera in
the Av ( aperature preferred) mode at ISOs of 50 or 100, most of the
noise you are describing will disappear. The camera should take very
nice images at ISOs less than 200.
Consult your manual on aperature preferred or manul setting of the ISO speed
Most likely, you've set the ISO value higher than necessary for most circumstances. You may have done this deliberately to catch some fast action, or you accidentally hit the ISO button without realizing it. If you reset to lower ISO settings, your graininess problem will probably disappear.
The faster the "film speed", whether you're using real film or a digital camera, the more grainy the pictures will be. ISO is the film speed. The ISO speed is set by pressing the ISO button (just above the "FUNC SET" button); it cycles thru AUTO, HI, 80,100, 200, 400, 800, 1600, then back to AUTO. If you've set the camera to AUTO on the control wheel opn the top of the camera, then you can only select ISO of AUTO or HI (which is slightly faster than AUTO).
The higher ISO settings are useful in low light conditions or to catch fast action, but those higher settings should not be used otherwise because of the increased graininess.
The reason for this is that the auto scene function chooses which ISO (light sensitivity) is needed to have a fast enough shutter speed to capture a still image (instead of a ghosted image). There is no way to change this. You can switch modes to P and specify the ISO you want to use (100-200 will give you a clear, non-grainy image, 400+ will be grainy). To capture a still image in low light with a low ISO, you need to use a tripod. Hope this helps.
ASA - very high 800, 1600 atleast
f- closest, 3.5,4. not more.
speed (ISO) if you want it to look in action so 1''. (second) if you want it freeze so faster..play with it
If you can adjust the ISO sensitivity to a lower number then the graininess will be reduced.
However, by reducing the ISO, you will need a slower shutter speed and a larger aperture. A tripod, table or other support may be necessary.
The "noise reduction" setting on the camera can also be adjusted a step up.
Taking pictures at full resolution and fine compression will also help. ---------------------------------------------------------------------------- Overall, at least try lowering the ISO, and using the flash brighter.
