Terrible grainy picturex

Graininess can be caused by a high ISO setting while taking pictures in low light situations. You could also have the picture quality set to a low megapixel setting.

You can try checking the user manual for those settings this is the link for that http://www.fujifilm.com/products/digital_cameras/s/finepix_s5700/images/fx_s5700.pdf

Hope that helps.......

Check the picture quality setting and make sure it's on the maximum number of MP's and highest quality.

You can download the camera's manual here; http://www.fujifilm.ca/x617.xml?XID=x15936
Those dials/buttons set the various camera functions, such; zoom, flash, image quality, playback etc. The manual will give you all the information you'll need to set and use your Z20.

1) Turn the camera on 2) Press the Func./Set button on the back  3) Press the controller DOWN key until you get to the size and quality menu 4) Press the controller Left or Right keys to select the mp size you want.

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.

Try going into the cameras menu setting and see if you can change the picture quality settings to the best setting! (the more mega pixals the better the picture when you blow it up or crop it!
If you cant figure out the menu come back and see us we will be glad to help!
Please rate my response to your question!
Thank You!

Are you in night mode? Sounds like you are in a high gain setting, like ISO 3200 or night mode.

try to uninstall the driver software and install again.. if nothing happens, try another webcam.
