Is anyone aware of what the latest thinking/guidelines are regarding digital archiving? For example, I've been advised always to use TIF format for digital photographs, as jpgs degrade in quality. I'm sure archivists have given digital records a lot of thought. What rules/regs/advice have you gotten about archives?
The first place you need to go is the ADS, they have Guides to Good Practice on a lot of this stuff. Including http://ads.ahds.ac.uk/project/goodguides...index.html
Digital Archives from Excavation and Fieldwork: Guide to Good Practice
While the technology is changing most of the principals of good practice have presisted.
I'm still waiting for someone to set me straight on a few points about jpeg deterioration my understanding is that they recompress everytime they are opened and resaved, not thankfully everytime they are viewed. This means if I open it in say Photoshop put a watermark on the image and save it again as a JPEG the image will be re-compressed and quality lost. TIFF images do not.
