Describe the difference between new and old technology re digital cameras.
A few pluses for todays digital cameras are the ease of their use, they allow fro easy printing which is able to be done on a home computer or visit a shop like Harvey Norman and get them to print them out. You are also able to delete any photos you do not like, which allows you to retake a shot at the time rather than being disappointed when you finally manage to get them printed in the old days. Digital photos can also easily be saved to your computer or discs and can also be easily added to reports or emailed to friends.
Some disadvantages are that you may need a lot of equipment to download and print from home e.g. computer, printer, discs, camera itself. Storage onto the computer may result in a loss of all photos if your computer crashes. Unless you have physical copies of photos that are nice to have and show around you have to open up your computer or show what you have still on your phone. Having a digital camera can get people used to having their photo taken as they are so common today that you can loose the surprise element and people say they were not ready so ask you to take another.
Some of the ways a digital image can be stored, transfered or manipulated using other communications are using a photoshop programme, store to a disc, put on line e.g. a blog site, sent and received in emails, on video and dvds.
Ethical Issues that may arise from photos taken may be gaining informed consent from those in the photos, letting them know who will see them, how they will be stored. In practice it may need to be asked who has access, are they safe and not just available to anyone who may think this is a nice photo, I will use it and put it in my report or on-line. It is also very easy for people to take photos now and the subjects may not even know they have been taken. There have been instances of people going up before the courts as they have used cameras to take photos of people in bathrooms etc. It is also very easy for photos to be manipulated and edited with technology available. As OT's we would have a responsibility to the clients and also to the practice setting where we are working.
Some ways that technology is being used in OT practices today are report writing, company reports and policies, staff photos, home modifications and visits.
The site "flickr" is a way of sharing and storing your photos with others. It is an on-line photo management and sharing application.
Other photo storage websites which also offer a similar service to "flickr" are photo bucket, you tube, and snap fish.
The difference between a digital and optical zoom is a digital zoom crops the image to a smaller size and then enlarges the cropped portion to fill the frame again. Optical zoom works like a zoom lens on a film camera with the lens changing the vocal length and magnification as it is zoomed. Optical zoom has better clarity and quality.
Wikipedia says that the term "megapixel" stands for one million pixels and is a term used for the number of pixels in an image.
