Paper archives can be destroyed by fire, water or vermin. A digital record can be copied immediately and located in a different place.
"Magnification" focal length of lens on digital cameras. The focal lengths of lens on digital cameras is about the same as on medium format lens. There is a change of about 1.5 in the focal to get the same effect. So thus a digital 35mm lense give the same result as a standard lense ie 50-55mm. This is a none problem.
Quote "The resolution is not as good as a cheap film SLR." Maybe/Maybe not -digital photography wins hands down for ease of use and in particular for looking at detail. They are different mediums and have to be used in different ways. I have a collection of 214796 digital photographs available to me in a matter of seconds.
Quote "Unlike film, where there is the not positive to rely on" why not print out the digital images. How many slides are printed and how many B&W photos are printed other than a contact print.
The heart of the objection to the introduction of technology is simply one of protecting jobs. There are a number of reasons for introducing technology:
Increasing productivity
Increasing quality/objectivity
To do things which are not possible without the kit.
As for the notion that there is a single archaeologist out there who does not know how to use the net......
