wall_olyD580.jpg

Here is a picture taken with the Olympus D580 Zoom digital camera of a curving red wall with rows of windows. In this picture, the camera was able to capture fine details such as the vertical and horizontal black lines on the wall, which is good. However, if you do a close up of the surface of the wall, you will find that the walls have become very noisy and dirty. They certainly didn't look that dirty when I was taking the picture! This is especially evident at the bottom right hand corner of the image, marked by the red rectangle in the image above. Feel free to download the full size picture above into your computer and zoom in to the region  marked by the red rectangle above and you will see what I mean by noisy. On the other hand, the same picture taken by the Nikon Coolpix 5700 will not contain such noise.

Take a look at the white walls on the left hand side of the picture marked by the green rectangle. Yup believe me, they actually looked grayish white when I took the picture but now, you can see that the walls look bluish (or greenish, whichever you prefer). My point is that sometimes, the Olympus D580 Zoom will produce false color in the image, making that region look fake and unnatural. If you take a look at the same picture taken by the Nikon Coolpix 5700, you will see that the false color is gone and the walls look grayish white, their natural color.
