Possible Problems
Since the light-sensitive component in a digital camera consists of discrete pixels, problems of Moiré, or interference patterns may occur when photographing fine patterns, such as textiles, geometric figures, and computer or TV screens. However, this is not a problem for most real-life situations.
"Highlight burn-out" is also a potential problem. Depending on the contrast of the subject, the lightest parts of the image may be so over-exposed that there is no image information, other than total white, in these highlights. Also, the reverse may occur. Shadowy parts of the image may become murky to totally black, because of the inability of the camera's sensor to cope with the contrast. Some digital cameras can show these blown highlights in the image review, allowing the photographer to re shoot the picture with a modified exposure. Others compensate for the total amount of contrast in an image by selectively exposing darker pixels longer. A third scheme is one used by Fuji film in its FinePix S3 Pro digital SLR. The image sensor contains an additional photo diode at each photo site that is of lower sensitivity and extends the range of brightness that the sensor can "see" in the highlights without burning out.

Water Applet
This Applet is a very good example of a visual effect of a water movement. Move your mouse over the image to see the illusion of moving an object in a still water.
Note: Internet Explorer users have to click once on the image to activate the control :-) When you move your mouse you can see the water is moving.
Click on the link above to get navigated to the special applet page, where you'll find more exciting applets, and some instructions on how to use it in your web site.
Actually you can implement those applets on any page of your website, but only one per page.If you use more than one of these applets on a single page, it takes too much processor and memory resources.
