There are many pluses and minuses in relation to digital cameras, including:
• Distribution of images: Because a lot of images that are captured by digital camera are kept on computer, it has become increasingly easier to send or distribute images without the person (s) in the photos or video being aware of it.
• Manipulation of images: As mentioned above, most digital photos are kept or stored on computers and as many modern computers have “photo shop” which is a devise upon the computers that can be used to change or manipulate different types of photos.
• Privacy: This is also similar to the distribution of images. As digital cameras are a great deal smaller than older cameras it has become easier to take photos of someone or something without other individuals knowing.
• Ease: digital cameras have made the process of taking and printing photos a great deal easier. It is even possible to save the pictures you have taken on a technical device and not print them out- saving money and keeping the photos longer, in better condition.
List some of the ways that digital images can be stored transferred and manipulated using other communications technology.
Many people who use or own digital cameras store their photos on their laptop or computer as it is cheaper than printing the photos out.
Digital memory cards can also be brought to extend the memory of your camera, thus it is possible to store photos on the camera itself.
As the technology of cell phones continues to increase it has become very acceptable and well known to send images from cell phones to cell phones.
The largest ethical issue that a digital cameras posse is privacy. As digital cameras are increasingly smaller it is so easy to take unwanted videos or photos of individuals, possibly without them knowing. These photos or videos can then be further put up on unwanted web-sites and broadcasted to the world via the internet, therefore allowing unwanted individuals to view these items.
Whilst on placement a saw digital cameras being use a great deal of the time, particularly in the community setting. There were many scenarios when they would be used however, the majority of the time, it would be in relation to a possible home modification. A digital photo would be taken to provide evidence whilst showing the clients current situation. This photo would be sent away along with many requests and justifications to enable who would possibly and hopefully provide the fiancés for the modification.
Flickr.com offers services, mainly around storing photos, sharing photos with different people and advertising yourself/photos (if you are a photographer).
www.facebook.com is another web-site which offers the same type of servies.
Optical zoom works just like a zoom lens on a film camera. The lens changes focal length and magnification as it is zoomed. Image quality stays high throughout the zoom range. Digital zoom simply crops the image to a smaller size, and then enlarges the cropped portion to fill the frame again.
Digital zoom results in a significant loss of quality as is clear from the examples below. It's pretty much a last resort, and if you don't have it in camera, you can do a similar job using almost any image editing program.
Digital cameras capture images as pixel elements, known as pixels. Simply put, a megapixel is equal to one million pixels.
Digital images are made up of thousands of these tiny, tile-like picture elements. The more pixels, the higher the image resolution.
Resolution relates primarily to print size and the amount of detail an image has when viewed on a computer monitor at 100%. (retrieved, May, 24, 2010, http://www.digicamhelp.com/camera-features/camera-parts/megapixels/)
