Digital cameras are electronic devices that are used to capture images and store them in a digital format. Digital camera photos are usually transferable from a memory card to computers where they are stored in files. Photos can be transferred or sent to other people over the internet by email, USB sticks, floppy disks, CD's and posted on websites and blogs like this one.
You need to have cables, batteries, memory cards, printer, ink and a computer to make the most of your digital camera. This is a negative factor as they are dependent on other technologies. Another negative is having all your images on a computer as the computer my breakdown and the photos are lost. A positive is the way we can easily edit and manipulate photos. They are quickly transferred from the camera to other devices which are a plus.
Ethical issues when using digital cameras include people giving consent that the photo can be shared with others. Some people may be in the background of photos that may feel uncomfortable that the photo is being displayed on the internet. Images can also be portrayed differently by editing and manipulating which can be an issue. It is harder to destroy photos once they have been sent and posted on various websites unlike destroying the original negatives.
OT's can use digital camera's when doing housing modifications so they can get an accurate image and then take it away review it and develop plans. They can upload pictures onto websites, advertising and for equipment. They can also be used in the work place for taking photos for staff badges.
Optical zoom works just as a zoom lens on a film camera. The lens changes focal length and magnification as it is zoomed. Digital zoom simply crops the image to a smaller size, and then enlarges the cropped part to fit the frame.
Megapixels are equal to one million pixels. Pixels are the little squares that make up the image.
