    What type of service? What causes this problem?

  • Igor Mayer Radovanov Aug 30, 2010

    On many models, the F-stop that is set by your auto exposure program is displayed when you look through the view finder. If you are seeing some really low numbers, and you are shooting with the built-in flash, you may well get a grainy picture. Try increasing the ambient light, or use an exernal flash - if your camera is fitted with a hot shoe for one.

    Your camera settings might also be to blame. Most digital cameras have a white balance adjustment, and yours might be off. You would need to refer to the manual for your model to figure out how to set this. You may also have your camera set in a mode it doesn’t belong in for the kind of picture you are trying to take. Does your camera have a "sports mode?" If you are shooting with that, it’s trying to use a fast shutter speed, which might not be letting in enough light yet again.

    Finally - do you have your picture quality at a high setting? Most digitals have low resolution modes that conserve memory at the expense of quality. It might be set to one of those.

    A few things can cause the graininess:

    1. Sharpening. If you shot RAW, and increased sharpness without doing noise reduction, this could make noise more pronounced even before you might use Unsharp Mask in PS.

    2. Color manipulation. If you've tried to push the hue, the minor differences between some pixels can become exaggerated. The effect can be compounded by increasing saturation.

    3. Resizing. Increasing size can definitely cause pixelation. Reducing size can, also, but this is rare and would require the conscious selection of a resizing method in PS that produces noise as a side effect.

    4. Contrast/brightness manipulation. Even the smoothest looking image contains a bit of noise, just by virtue of having one pixel be different from another. If you push contrast or brightness too far in any direction, you'll exaggerate the differences between pixels, and it will look like noise.

    Your second link is broken, so I can't comment on the unedited version. Regardless, I wouldn't consider taking the camera into a shop until I've confirmed the problem is consistent among several unedited photos in RAW format.

Why does it only play in black and white?

sounds like you don't have the cables plugged in properly.

you either are just using a single cable for video out + 1 or 2 for audio (digital or analogue)

or three cables for component video out + 1 or 2 for audio (digital or analogue)

if you connect the video cables to the wrong ports on the TV you are not going to get a good output.

component video out should be quite good quality. so i recommend connecting that way

We just bought a 40"

Without HD content, the TV will scale up the smaller-sized video. This means it will "stretch" the content, making it grainy or pixelated. The only way to get better quality video is to get HD service.

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.

Grainy picture

Hi and welcome to FixYa,

Initially, some ideas you may want to try/consider:
  • other than the TV, all switched off and unplug. Try evaluating the reception of any/all TV channels;
  • if quality is bad, either the tuner (least likely) is bad or a problem with your cable system/provider;
  • if the quality is good, then either the DVD or the game console has an RF modulator that interferes with the Toshiba's reception;
  • if the grainy picture is when using the Audio/Video inputs, then it would not be the tuner but rather the video processor;
  • should the tuner really require replacement, it would be relatively easy since it is a single block/assembly with a couple of pins and a mini coaxial connector;
  • best approach would be to reference a Service Manual. Pls bear in mind that voltage check requires the unit to be powered on and therefore exposes you to potential electrical hazard.
Check and perform preliminary visual or necessary inspection. Pls post back result(s). Good luck and Thank you for using FixYa.

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!

Go Ahead. Use Us.

Grainy Pictures

This camera with the ISO set to 100 ASA, the electronic zoom turned off, and with the mode on Automatic "A", should take very good pictures.

I would give the camera to the manufacture for service, and include some samples of what the results are. It would be recomended to do this while the camera is under warranty.
