Unfortunately this is a problem that ALL digital cameras suffer from, not just your particular model. It might be less noticeable on other cameras but it still happens.

High ISO settings and/or low light levels will result in grainy images.

Think of a TV studio. That's why they have such bright studio lights!

What is a Good Iso for a good picture


ISO refers to the sensitivity your camera has to light when taking a photograph.

A lower ISO value is generally better as a high ISO value can reduce the quality of an image and cause it to appear grainy or noisy. Therefore, you should always aim to use a low ISO value. When outdoors in a bright light, an ISO value of 100 or 200 should be fine.

Higher ISO values can be used in situations where, perhaps, you are indoors, there is low light or you cannot use a flash. A higher ISO value such as 800 or 1600 can be used to compensate for the lack of light and it will brighten the image for you. A high ISO value can also be used if you wish to create a grainy effect in the image but this can be easier to achieve afterward on a computer.

Hello! I actually have a TZ3 and have been having problems with the quality of the pictures without using the zoom (grainy) as well as problems with the quality of the picture when using the zoom...


Hello, yes a few suggestions "grainy" could be from an auto ISO setting the sensor speed high as in possibly ISO 400 even 800 or higher you get the pictures but it's grainy. On pocket point and shooters this is most often the case in full automatic modes and on your camera it's called "Intelligent ISO Mode" You should consult your manual and select a more user selectable ISO speed manually. Another feature with your camera is image stabilization this you can turn on or off preferably off when the camera is mounted to a tripod. Okay for the blurry part on the zoom the quickest way to explain this is every tiny movement you make holding the camera is magnified 10 times, this is where the image stabilizing feature would be handy. Jennifer in my younger days I could hold a 35mm camera with a 300mm lens steady at 1/60 of a second now I use only a 200mm lens with image stabilization "on" to get the same results. What you have is a full time auto everything camera if it's working for you it doesn't matter if it's 3.5 years old. You are still working with a 7.2meg camera with a print capability of 11x14. hope this answered some of your questions.

Really Grainy low quality pictures with my new camera.


Try shooting with ISO value of 200 or less; or set to "Auto".

If you're missing the manual, you can get it in English, here. Page 76 briefly discusses ISO settings. This camera can select an ISO as high as 1600. ISO has to do with graininess of film - the higher the number - the more grainy the images. Higher ISOs are selected when light levels are low and no flash is used or is usable (such as when the subject is too distant). Some photographers use higher ISO settings with high shutter speeds to stop fast moving objects (like wheels on a race car). The grainier the film, the quicker it captures light. Fime grained film takes longer to capture light.

Generally, pictures taken outdoors in sunshine look best when ISO is 100 or less. 100 is a good choice for well lit indoor pictures, too; but may be better with an ISO of 200. ISO works like this:

If a picture can be properly exposed with an ISO of 100 in 1/15 sec, it would require only 1/30 sec at ISO 200, or 1/60 sec at ISO 400. When you double the ISO value, the exposure times are halved. What's the big deal about 1/15sec, 1/30 or 1/60 sec you might ask? Easy! the picture will probably be blurry at 1/15 and even 1/30 sec exposure time, due to the camera recording even the slightest movement of your hands. You'll need to supply a tripod or do something else (such as increase the size of the opening of the aperture or f-stop) to get a properly exposed image.

I hope this helped - if it isn't an ISO problem - let me know. Good luck!

My photos are coming out slightly grainy in low light. Have played around with ISO and aperture etc but no luck. All modes have the same problem. Camera= canon powershot S5 I5


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

Pictures come out very grainy


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.

I hope this helps you.

How to overcome Grainy photos on some in door shots with my Canon A710


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.

Photos very grainy. Have quality set to super fine.


What camera?
Is it a pocket camera where the lens in internal? that would explain some of it.
Go into your menu and look up ISO and make sure its not set to anything above 400 if you are worried about digital grain or noise.
for the sharpest image you should have it set to the lowest speed setting.

hope that helps,
Caleb

Hey bljack,
There are two main causes of grainy images with digital cameras. The first cause could be that the image size is set too low. I would have it set to the highest size and quality possible, because you can always reduce an image size but you can never make the image size bigger. A list of the possible image sizes are on page 21 of your camera manual. The next main reason for digital noise is having the ISO set to high. ISO is the sensitivity of the digital sensor, and the higher the sensitivity the more digital noise that will be in your images. I would very rarely have the ISO set to higher than 400. I have provided a link to the camera manual below. I hope this helps!

Grainy Pictures


With the iso set on auto mode it will change depending on the light and anything above iso 200 is very bad on this camera i know have the 717 and it does a lot better but if you can set the iso yourself and take it off auto allways use 100 or 200 for low grain.

Having problems with the flash\ blurred and grainy images


You should not use the flash for these shots (unless you connect a powerful external flash), it won't help you at this distance. You should use the shutter priority mode and experiment with shutter speed (no flash) to get the best result - for sports action it should probably be faster than 1/100 sec. If the light is too low you may use higher ISO setting - 200 or 400 (though higher ISO will result in grainier images, it may be your only option for blur-free photos).
