| | The Mystical Zoom Effect Of Digital Cameras Explained In Plain English | | Most of the digital cameras within the mid-priced range include a 3x/4x lens - the first number refers to the optical zoom with the second number referring to the digital zoom. A few of the lower-end priced cameras have only a digital zoom, but their photos are rather dull and slightly fuzzy. The zoom effect in a digital camera is similar to, yet different, from that of a conventional camera. It brings distant subjects closer.However, in a digital camera there are two kinds of 'zooms'. The first is similar to that of a conventional camera and is known as the optical zoom. The second is the digital zoom, and is more interesting. It 'simulates' optical zoom by enlarging a portion of the image -- that is the digital zoom selects a portion of the photograph and blows it up.The zoom effect should not be confused with photo editing, where an image editing software is used to crop and blow a picture on a computer screen. Cropping a picture can refer to enlarging the main subject, or an area of choice - thereby eliminating the remaining parts. Another misconception associated with digital zoom is that it is very handy in capturing long distance images. Nothing can be more... | |

| | How Can I Use Digital Cameras To Save The Planet? | | The issue of hazardous waste receives less attention than other environmental threats, with over 80,000 chemicals now in existence - not counting the additional 1,500 new chemicals developed on a yearly basis, with many being introduced into the industry fields. There seems to be insufficient data demonstrating the effects of every chemical out there, but what data is available shows that human health and the environment is in trouble.The good news is, of all the environmental threats, the hazardous waste issue has the most successful solutions available to it. Scientists state that hazardous waste could be reduced about 1/3 by using the available technology and methods already present, such as using the more recently developed digital cameras.This is because as more and more people moved away from conventional cameras for easier photography with higher quality results, they were unwittingly reducing the use of chemicals that were earlier being used to process the film. These chemicals, especially the developer and fixer solutions, had become serious environment hazards.The United States laws have required that the "spent... | |
