Grainy pics When I have the camera on sport the pictures turn out really grainy. I'm zooming but it's not in the digital zoom. What can I do to fix it?

Answer This Question
  • Stealth777 Mar 03, 2009

    In relation to the "grainy pics" i came home and did some testing with the camera. I shot a poster on the wall and noticed the F number as well as the shutter speed. took the picture and it came out great. Went to manual mode shot a picture with the same same shutter speed and F number but with all the different ISO speeds on the camera and neither came out as good as the one shot in AUTO.. So what could be wrong there? Could it be the shutter speed and F numbers are not correct?

When using sport mode the ISO jumps to 400 or more, and this is very noticeable in the grain of the picture. S3 renders good detail up to ISO 200. My advice: Set ISO to 200 in Tv mode, then set the shutter speed to 400 or something like that using the < > buttons. You have to try the best speed under the light you are. If the light is very good, perhaps you can use ISO 100 and get much better results.

All of my shots are grainy--really grainy. My old 8 mpx camera took beautiful, tack-sharp photos. This is 14 mpx and it looks terrible. Someone suggested that maybe the contrast needed to be adjusted ...?...
Unfortunately with higher mpxs sometimes you pay for it with higher noise levels. The smaller pixels are more sensitive and can cause noise. A couple of things you can do to help control the noise is make sure your pictures not underexposed, you may need to bump up you exposure compensation a little as long as you don't end up too bright.
You can also try to shoot with the lowest ISO setting your camera has. High ISO = NOISE!
Last you can run your photos through a noise reducing program such as"Noisware" their community edition is free. http://www.noiseware.com/download_nwsa.aspx
PS Contrast settings will do nothing for noise.

The picture I took look grainy. Just started doing this.. do you have any suggestions Thanks susie
If the pricture was taken in low-light then it just will look grainy. If not then make sure you're zoomed all the way out (i.e. not using Digital zoom as opposed to Optical Zoom) and make sure the resolution settings on the camera Menu are set to the highest setting.

I have a new polaroid I735 camera and the pics are very grainy and blurry even when viewed through lcd screen. Any ideas?
maybe you zoom in a lot and then it would be normal and if the pictures come out fine, i wouldn't worry about it but if the print pics come out grainy and blurry i would take it back if you have warranty

Zooming with Olympus Stylus 820
Hey missy0528,
There are a few reasons your images might be grainy, one of which is your image quality is set to low. I would always have the camera set to the highest resolution possible, because you can always reduce the size of an image but you can never make it bigger. Another cause of grainy images in digital cameras is the sensitivity of the camera (ISO) is set to high. Since you are only seeing grainy images when you use the zoom the reason for the grainy images is most likely do to using the digital zoom. All a digital zoom does is crop the image much as you can do in some computer applications, and by doing this you greatly reduce your image quality. I would never use a digital zoom. Your camera has a 5x optical zoom and a 5.6x digital zoom. I would only use the optical zoom. I hope this helps!

Sincerely,
Allan
Go Ahead. Use Us.

Photo quality
It will be grainy a bit specially in digital zoom and even in optical zoom to the full level it might become grainy as camera is unable to absorb all the light from distant object......

Super Zoom
In addition to the optical zoom, this camera is equipped with a super zoom and digital zoom for taking telephoto and wide-angle shots. The super zoom and digital zoom cannot be used at the same time. Super zoom is used to extend the optical zoom up to 14× magnification. However, the resolution is automatically fixed at 1600 ×1200. Digital Zoom is used to extend the maximum optical zoom to approximately 40x. However, pictures taken with the digital zoom may appear grainy. Camera shake is likely to occur at these higher magnifications, please see “camera shake” question for further details on this.

Images appear to be very noisy or grainy
When DIGITAL ZOOM is set to ON in the MODE MENU, the lens can zoom into the Digital Zoom portion of the zoom by pressing the zoom (T) button. When you see the zoom indicator on LCD enter the red portion (towards Tele), the image in the viewfinder will become closer. However, since the D-630 is using the digital portion of the zoom, the lens doesn't physically zoom, it takes the existing image and enlarges your image using an electronic program. This can result in a “noisy” or “grainy” look to the image. This is normal when using the DIGITAL ZOOM. The DIGITAL ZOOM can be turned OFF to prevent you from using this portion of the zoom. Locate DIGITAL ZOOM in the Mode Menu and set it to OFF.
