Thank you to all who responded to my query. Your questions and responses have in turn challenged my thinking about the original problem. While the "functional" master will need to be quite large to meet many potential uses, I wonder if we need an "archival" master of a surrogate of a surrogate of a object? A file created through direct digital capture of an object, however, will need to replicate and hopefully exceed the detail and quality of the first generation surrogate transparency.

I find that on the occasion that you need to make that unique use, it is better to rescan for that specific purpose, this might be a large wall mounted displays for exhibits. Since you have transparencies, I assume you have been using them for printed material - posters, postcards, catalogs, promotional material and possible some electronic presentations. The future of digital imaging will improve the image we can display electronically, but I don't think it will change the resolution of the printed image. You, however, may want to print a small detail at a larger scale. This being considered, I would scan at a resolution to be able to print a quarter of your image at your 90% commonly printed size and dpi. And as non PC as it is, I don't believe in archival digital images anyway. Just because we can capture huge images, should we? Digitize for Access, yes and mass distribution, but not for preservation, except as it reduces handling of the original. The right resolution for proper access depends on the material being scanned. -- Trudy Levy Consultant for Digital Imaging Projects Image Integration 415 750 1274 http://www.DIG-Mar.com Membership Chair, Visual Resources Association http://vraweb.org Images are information - Manage them On 10/12/04 1:53 PM, "Amy Stidwill" <astidw...@hillwoodmuseum.org> wrote: > Peter, > > Yes to your second description of an image that can be used to make > derivatives for a variety of purposes. > > Thanks, > Amy > > Amy Stidwill > Visual Resources Manager > Hillwood Museum & Gardens > 4155 Linnean Avenue, NW > Washington, D.C. 20008 > (202) 243-3910 phone > (202) 966-7846 fax > astidw...@hillwoodmuseum.org > > > >>>> p...@digitaltransitions.com 10/12/04 04:12PM >>> > Hi Amy > > When you say master, are considering this an "Archive" type image (a > file that can replace the original film if destroyed), or an image that > > can be multi-purposed for offset press, web, analysis, research etc.? > > > On Oct 12, 2004, at 3:31 PM, Amy Stidwill wrote: > >> I am in the process of reviewing and updating our standards for > master >> digital files as we switch to a new collections management system. > We >> have not entered the realm of direct digital capture and are > scanning >> primarily from 4 x 5 transparencies.
