Washed out photos with lines running through them

Camera noise can be common during autofocus, image stabilization, and of course pressing the shutter release. It seems possible that the noises you noticed are part of normal the normal photo taking process, since you only hear them when taking a photo, not when reviewing photos (a process which doesn't use autofocus, image stabilization or the shutter release).

If you're not experiencing any problems taking photos, the sound may just be part of normal camera operation. However, if you're still concerned, I recommend you take your camera to your local camera store to have an expert listen to the sounds.

This sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free worldwide, and may also include free shipping both ways (free shipping varies with countries). This is regardless of your camera's warranty status. Please check this link for more info.

Applicable cameras include:
A40, A60, A70, A75, A80, A85, A95, A300, A310, S1 IS, S60, S200, S230, S330, S400, S410, S500, SD100, SD110, IXUS V2/V3/300/400/430/500/II/IIs, IXY Digital 200a/300a/320/400/450/500/30/30a

If the menus and icons look normal, but images are distorted or discolored, you may have an image sensor (CCD) problem. See Canon's service notice regarding this issue here. Canon will repair your camera at no cost regardless of warranty. Contact them at your regional Canon service agency.

The Canon A95 has been known for taking noisy and grainy photos. Try using a low ISO setting of 50 or 100 to see if that helps. Using auto ISO or ISO above 100 will put more noise/grain in your photos. Also, always shoot in the best lighting situation possible. The more light the better. You can always improve your photos with good editing software too.
I hope this helps and good luck!

You have over exposed pictures due to the shutter sticking.
The video is the clue to the problem. It doesn't use the shutter.
Shutter needs to be cleaned. This is no easy task im afraid

Bad CCD.
Video uses only less then 1 megapixel, that's why it's OK

That is weird! Got to be a cheap or bad card. I would call Nikon about that one! Use their help line at 1-800-NIKONUX

Sounds like the shutter isn't working properly.

It should be looked at by at technician.

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.

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

Your camera has a defective CCD imager. Please return the camera prepaid to Canon in New Jersey, they are replacing the CCD at no charge to the customer. This is a known issue and is resolved by many of the manufacturers using the Sony CCD element in their cameras at no charge. Good Luck my friend. Joe Weibel customelectronics.org
