Re: camera

Please more explanation - 'The ISO'
The iso related to image quality- you appear to have it set to low quality setting which gives the maximum number of images but of low resolution. Reset it to HQ or SHQ for best results.
Check your manual re how to do this.
The is usually a more comprehensive manual of the software CD in PDF format

Why are pictures grainy, Photos are usually very crisp. This time every one was grainy like low res when I have it set on High. The camera is a Canon PowerShot S3 IS

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:

You need to check your ISO setting and the picture quality you have your camera set to. It should be at the maximum megapixels and fine quality and the ISO should be below 800 or even 400.

I bought a canon sd1100 a year ago. It used to take great pictures. One month ago all pictures taken have been grainy. Do you know why>?

Could be that ISO settings were accidentally changed. The main annoyances with high ISO setting are the noisy (grainy as you say) images. Check the iso settings if you are shooting in modes other than automatic shooting.

Polaroid i1035: Bad quality pictures, appear grainy and fuzzy

The grainy effect has to do do with the ISO setting, try adjusting that. A higher ISO is generally better for darker conditions. I have noticed that this camera frequently takes grainy images.

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.

Grainy pictures

grainy pictures are possibly casued by a very high ISO (sensativity) setting, you should be on 100 or lower for best normal shots. Higher settings are for low light and custom shooting in strange lighting or aperature/shutter speeds. Try full auto setting.

Fuzzy, Grainy Pictures

This camera is a perfect one to show the problem with the tiny sensors in the typical point and shoot. From the same sensor size that previously gave 2 or 3 megapixels, Canon now extracts 7.something. In order to do that, they have to turn the gain up so that each pixel actually puts out a signal to be recorded. The natural outcome of that is noise. In this camera, Canon includes heavy noise reduction software that softens the image in order to reduce noise at the various ISO settings above the minimum one, but the result is still a mix of noisy and soft or fuzzy images.

However, the noise should be well controlled at the low end of the ISO settings.

I suspect you have somehow gotten the ISO setting set up higher than the lowest one. Use the four-way controller to access the ISO and set it to the lowest (80) value. This should give you noise free shots.

As an additional suggestion, read the concise review of this camera at Dpreview, the link for which I've provided.

If you have any questions, please let me know before giving this answer a rating and I will provide it. Thanks.

Noisy pictures = High ISO in almost all cases. Select ISO manually (select a manual mode where you can control the ISO) and set it to the lowest possible value. To avoid camera shake, place the camera on a tripod or another sturdy surface; or use the flash
