Question about Konica Minolta DiMAGE F300 Digital Camera
Hello, I recently purchased a Minolta F300 5MP digital camera and I am just learning how to take proper digital pictures. I noticed that at the 640 x 480 Standard and Fine settings, some of the images have a noticeable 'ripple' along any of the straight edges of objects like a wooden shelf, the front of a TV, that sort of thing. Any idea what might cause this? Is this 'noise'? Any help would be greatly appreciated. If you think I should return the camera, is the Fuji F700 a better model? Thanks in advance

The "ripples" to which you refer are called commonly called "jaggies". It is a phenomenon present on most cameras but on some it is more pronounced. Another problem is visible moir? patterns on repeat detail. These are usually the result of a problem with the CFA interpolation or sharpening algorithm in the camera's software. In any case, the result is noticeable "steps" on diagonals which shouldn't be there. The problem of moir? patterns is usuall more visible in finer details such as hair (as shown in the examples below) or repeat areas of an image (such as railings / fence posts into the distance). There is really nothing you can do about it, except to keep your file size and resolution settings on high for critical photos.

It's an inevitable consequence of using a low resolution jpeg. Try setting your computer monitor to VGA resolution (640x480) and you'll make a similar mess of images it displays - only worse, because the large screen blows up the image. You should use a higher resolution setting and invest in a bigger memory card for the camera if need be.
