I have the A620 and it is pretty nice, in my opinion.

What ISO are you shooting at and what light conditions?

Printing them?

It's a Sony Cybershot S650. Fix plz.
Lower the ISO. This will affect your shutter speed, so you'll have to stabilize your camera somehow. It'll probably be next to impossible for events and parties and such, but if you're doing something like taking a photo of your PC setup, lower the ISO down as much as possible, put your camera on a stack of books, and take the photo.

I have no idea. Photography really isn't my thing. I bought it for casual use a couple of years ago. Lighting varies but the grainy distortion is worse in darker images.

And no, I don't print my photos (yet).

So the "ISO" level is the problem then... I guess I'll have to try and find my manual... it must be around here somewhere.

Yep. High ISO -> Image sensor is more sensitive to light. The downside is it gives a grainer look to your images. Check out the guide in my sig to see some examples of how ISO can affect the image.

To try and explain what they are saying I have quote reincarnated's guide below.

If you've ever taken your point and shoot to a dark room and ended up with a grainy picture, you've experience with image noise.

Image noise is, to be short, the grainy look that images get. Noise is affected by both ISO and the size of the image sensor, but since the sizes of most DSLRs are the same, the biggest factor for image noise is ISO.

ISO is a measurement of how sensitive the image sensor is. The higher the ISO, the more sensitive the image sensor and the less light (smaller aperture or faster shutter speed) necessary for a proper exposure. Unfortunately, cameras make the sensor more sensitive by running more electricity through it, which can lead to the pixels becoming hot, resulting in that grainy look.

To show the difference, we now turn back to the photomajig, now with the image cropped to highlight the image noise:

ISO400


ISO3200

As you can see, while you can start to make out the noise at ISO400, it's extremely noticeable at ISO3200. Keep in mind that newer DSLRs can handle noise better @ ISO3200, and full frame cameras can chew up that ISO and will pop out a clean image, but the principle is the same: high ISO = more noise.

would you like to show us a couple of your terrible images so we can understand what the issue is?

Are you shooting in auto? what lighting conditions are you shooting in?

If its in AUTO and the camera has the no flash option turned on..then the camera automatically changes the ISO(Pronounced Eye-ess-oh not iso, just FYI), shutter speed, aperture for the given lighting conditions.

Make no mistake, the slower the shutter speed in combination to a high ISO will produce acceptable lower noise images...the opposite will be found for fast shutter speeds and high ISO

Glad to hear it worked

Keep in mind that point and shoots have smaller image sensors than DSLRs, so they're more prone to noise. This means that the ISO values I quoted in my guide will not work for a point and shoot. While my DSLR can go up to ISO 800 before noise bothers me, my point and shoot can only go up to ISO 200 before it gets noisy (and even then ISO 200 is pushing it a bit). I'd imagine it's probably the case with your point and shoot as well.
