I'm curious to know what settings you use in scanning & saving your artworks for archival purposes. Currently, I'm saving them in TIFF format (600dpi). I end up with 2 files, 'cos I would save one TIFF version for PC, and one for Mac. Wonder if that's an overkill... anyway, I'd really like to know how others archive their works.
I started scanning my works after I discovered the pages from my earlier pieces (about 10 years ago, all on paper) were turning yellow, and the colours from paints were no longer as vibrant (same issues that any art museum would face).
What didn't seem to deteriorate as fast was the inks -- works outlined with Indian Ink, to be exact. The black lines were still very sharp, which contrasted with the yellowing paper.
Investing in humidifiers is out of the question. I used an acrylic fixative to seal the works in. That helped to some extent but Father Time and Mother Nature still manages to catch up.
Digitising the works is a longer-term solution (though I recognise it has its own set of issues, like what if the software/ hardware or operating system isn't available anymore).
So I want to make sure I scan and save my art work appropriately. Also, I'm harbouring hopes of producing a Larger-Than-Life image in the future. Last thing I need is to blissfully assume that I've digitised my works correctly, only to find that when I need the digitised copies they aren't in the optimal formats. By that time, the originals might not be around.
