”A new technology is rarely superior to an old one in every feature”
This statement in relation to digital camera technology is I guess talking about how digital cameras and older film cameras both still take pictures. Some of the pluses that I think digital cameras have compared to film cameras are that you can preview your image, also that you only need to print the images you want, so not wastage. Some of the negative things about digitals are that you don’t get that whole surprise when you get the photos developed. Also that digital you cannot be involved in the whole process and develop you own.
Digital images can be transferred and stored very easily, you can keep the images on small memory cards or cds, or even in online photo albums. However digital images can also be manipulated for good and for bad. You can remove the red eyes, touch up blemishes, but you can also change the appearance of someone and sometimes this is not for the greater cause. Just look at how some models have their photos manipulated to make them look better or skinner. There are other ethical issues relating to digital image capturing devices such as the distribution of the photos, the copyrights and how they can be manipulated. Another issue is the confidentiality of the images and who sees them if they are published on the internet.
In occupational therapy practice digital images can be used when doing a home visit to assess for any housing modifications, the images can then be used as a record.
