In this tutorial, we looked at the use of digital cameras.
"A new technology is rarely superior to an old one in every feature." We discussed this quote in reference to digital camera technology and found that there are both positives and negatives with digital camera compared to a film camera. The traditional film camera required an element of surprise when the film was developed and fewer photos were taken, therefore one could say the photos are more meaningful. However, digital cameras have a cost effective way to store photos on the computer and can choose the photos to be developed.
Digital photos can be stored, transferred and manipulated using many free or bought software programmers available. Photos can be manipulated using programmes such as photoshop. Photos can be transferred using iPods, mp3's, memory sticks and emails. Photos can be uploaded and shared with communication programmes such as flicker, face book, bebo and blogger.
With the easy access to photos can be displayed, transferred and stored without people's permission. Due to this ethical issues can arise such as the uncontrolled distribution of photos without people even knowing about it. Once the pictures are on line it is beyond our control and photos can be taken without the subject knowing or they could be manipulated and shared to the public. This presses on ethical considerations regarding the person in the photo and their privacy for once it’s online practically anyone online can view it.
Digital cameras could be used in Occupational therapy as a way to collect data, such as taking pictures of a clients house regarding housing modifications, taking pictures to document group activities, them using adaptive equipment. The use of digital cameras is increasing in Occupational Therapy.
Flickr provides a way for people to upload and share photos and videos either publicly or privately.
Face book offers a similar way to share photos with friends and family.
There is often confusion between digital zoom and optical zoom. Digital zoom is more pixilated when it is zoomed or blown up. Optical zoom is recommended as the quality of the photo remains a lot clearer then digital zoom when it is blown up. To have at least 3 times optical zoom is recommended.
Megapixel refers to the pixels (look like squares) that make up the photo.The more pixels means the better the quality photo.There are 1 million pots of light. 6 or 7 pixels are recommended for good pictures.
