Two possibilities related to the amount of light reaching your camera sensor.

The sensitivity ISO is set too low, perhaps 200... set it higher, like 800 or 1600 ISO

[Sensitivity]


Your "resolution" may be set too low, maybe 3 Megapixels. Set the resolution to at least 6 megapixels.

Accidentaly deleted photos on my memory card. My camera is Pentax E90


Take no more pics until you've recovered your photos, take the card out of the camera. This is to reduce the chance of you overwriting some of your "lost" photos. There are many good freeware photo recovery software options that may help you recover your photos. This article reviews and outlines several of the better ones:

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.

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.

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.
