Storing Digital Images
As with all technology there are always some things people like about the old that is not carried on to the new. Digital cameras have given us the opportunity to all become overnight photographers taking a lot more photos and seeing them before printing them so supposedly being more economical. It also affords us the luxury of storing our pictures in different ways in case of disaster. For example on a disc, the computer or a hard copy.
Informed Consent
“Informed consent is a process rather than a one-off
event. The essential elements of this process are effective
communication, full information, and freely-given
competent consent” (Fraser, 1998, p.1).
Informed consent is an integral aspect of service provision.
It is also an ethical and legal requirement under the codes
of ethics of various professional bodies, the Health and
Disability Act (1994), and Code of Health and Disability Services Consumers’ Rights (1996).

Use of Digital Images in PracticeDigital images are being used in Occupational therapy practice to make others aware of some of the difficulties faced by others that are less able. For example: Occupational Therapy at Grand Valley State University. Retrieved March 14, 2009, from http://www.gvsu.edu/ot/index.cfm?id=9D296622-CFA0-EB34-F9EDC9408F00E6C7 uses photos to highlight the interaction of OT's with clients and to promote the school.
Images are also used to enhance the skills and diversity of an OT, such as seen on the following website that has links attached to each image.

Occupational Therapists are using digital images to show supervisors or other therapist. This is to ensure correct seating/posture/movements/equipment installation are in place for a client instead of creating another visit to the clients residents and wasting time for both parties.
Flickr
There are other ways in which people display their digital images which is less formal and offers others the opportunity to comment on the images. One such site is Flickr.com offering people an opportunity to showcase their photos and talent (or lack of) to others. Flickr's aims are 1. We want to help people make their content available to the people who matter to them. and 2. We want to enable new ways of organizing photos and video.

"Jpeg format was designed to transfer graphic data and images via digital
telecommunication networking and was generally used to hold and transfer full
color photo realistic images. Before Jpeg, there were very few formats, which
supported 24 bit halftone images. TIFF and BMP formats allowed holding 24 bit
data, but they failed to perform a loss less compression of the data, which
contained thousand colors from the real world, on the high quality
level. Jpeg compresses photos though with quality loss. Compression algorithm
is that data are deleted for deal location (it allows to raise the compression
degree). Data are hold as pixel block in a certain color with intensity
information save (the matter is that a human eye discerns disintensity better
than discoloration).
Photos and multi-color images, transferred in this
format, are ideal for networking. It is not possible to refine Jpeg images,
though it is possible to debase them by decreasing the file size.
Jpeg format is primarily used to hold photo realistic graphic images with a large number of
colors.
Compressed data capacity depends on image contents. Compression
degree may come up to 25:1 without visible loss in quality.
Jpeg supports, Progressive Jpeg standard, which conceptually looks like interlaced in Gif
format. That means that Jpeg Progressive format images are loaded by parts,
which are displayed, as they are loaded. Such format is good for large files.
Unfortunately, it is a new standard, so some programs may not support it".

Digital Vs Optical Zoom
Finding the Difference Between Digital and Optical Zoom; go to Digital Vs Optical Zoom at http://www.pantherproducts.co.uk/Articles/Digital_Camera/digital_optical_zoom.shtml
Digital zoom according to Wikipedia - is a method of decreasing (narrowing) the apparent angle of view of a digital photographic or video image. Digital zoom is accomplished by cropping an image down to a centered area with the same aspect ratio as the original, and usually also interpolating the result back up to the pixel dimensions of the original. It is accomplished electronically, without any adjustment of the camera's optics, and no optical resolution is gained in the process. Wikipedia. Retrieved March 14, 2009 from, http://en.wikipedia.org/wiki/Digital_zoom
Optical zoom is magnification created by a lens. This type of magnification is a "true zoom" and should not adversely affect image quality. Optical zoom should be your first choice for magnification whenever possible. About.com Photography. Retrieved March 14, 2009, from http://photography.about.com/od/camerabasics/qt/digvsoptzoom.htm
What is a Mega pixel????
"A mega pixel refers to one million pixels, and is commonly used in reference to digital cameras as an indication of resolution capability. A pixel is a tiny square on a computerized display that is so small it appears as a dot. The display screen is a solid grid of these squares or dots, which can be easily seen with a magnifying glass. The more pixels or dots that make up the display screen, the clearer the resolution or image will be. Greater numbers of dots or pixels allow for more refinement of the image, which results in higher, truer image replication". Wisegeek. What is a mega pixel?
