Today we looked at the different uses of digital cameras and how the the technology surrounding then has advanced over the years. We looked at the different advantages and disadvantages of digital camera technology against the traditional film based cameras:
Advantages for digital cameras:
-Ability to capture a moment in time and be able to look at the image directly afterwards.
-You are able to take a digital camera anywhere (it can fit in your pocket!)
-The ability to take photos are not just in the form of a digital camera- you may take pictures off your cell phone, or your your ipod/iphone.
-You can alter the colour, brightness and play around with the images on a picture such as removing red eye, or zooming in and out. Digital cameras also provide you with the ability to save any images to a disk or your computer.
Disadvantages for digital cameras:
-There is limited privacy for people having their photo taken due to the fact that a picture may be taken from off a cell phone causing a person to be unaware.
-Pictures/photos are more disposible as people can freely delete images by the click of a button.
-This means that photos tend not to be as treasured as they once were.
-Digital cameras need ongoing charging, or changing of batteries.
Ditital images can be played around with, stored, transferred and manipulated through the use of specific communication technology. Some of the ways in doing so may be:
-Saving images to external hard drives.
-Printing images off.
-Transferring and saving images to a computer or CD.
From this easy and accessible nature of photo taking, ethical issues may arise which need to be considered in order to be participating in safe and ethical practice- This may involve:
-Informed consent on taking, using, or publishing somebodys photo.
-How to take and use photos on and off websites (if and when wanting to use them as a part of your own work).
Digital images may be used in occupational therapy practice as a source of evidence to provide for other carers such as ACC, enable or to other therapists. Having the use of a digital camera when specific details of a clients home environment must be remembered can come in handy.
'Flickr' is an online networking site that allows people to share photos, post information, add different contacts and join groups. Another online photo storage website that is similar to Flickr is : www.photobucket.com
It is interesting to know for those who are unaware of the differences between digital and optical zoom, and megapixel...
-Digital zoom is the zoom of the lens, which allows you to capture an image closer than it actually is, or further away. It props the image taking the middle of the shot, having the ability to blow it up to a bigger size.
-Optical zoom is the quality of a zoomed image, therefore a closeup picture will still remain clear.
-A megapixel is the smallest element of an image that can be individually processed in a video display system- (A megapixel is 1 million pixels).
