Re: Standards for Digital Masters
I hope this will help. Some of the questions issued below come to us after reading some of the articles already mentioned. In the Photographic Documentation Division of the Portuguese Board of Museums, working for the last 4 years in a imaging information system, we think no one can say there are reference standards for digitizing photographic material. Surely you are aware that digitizing is a process so hungry of specialized resouces, so it hardly can be duplicated. There a number of questions that, in our point of view, are crucial to the whole project and preceed the definition of standards: What is the volume of suports to digitize? What are the actual retrieval necessities? What will be the retrieval necessities of the Institution in 5-10 years? What are the human, material and storage resources involved? What human, material and storage resources will be available in medium-long term? Does the IIS manager have the answers to this questions? Does the board of directors of your Museum are aware of this issues? After finding the answer to this and other questions that specifically will pose to your museum, the number of bytes, pixels, layers, etc. i.e. standards will became easier to figure. >From our experience in trial and error we think there must be a full commitement of the whole institution in the project. In our case it was the only way to deal with the digitization of almost 50 thousands 4X5inch transparencies of artworks of the portuguese museums over the last 4 years.

You might also want to make sure that your camera / scanner can deliver 4000 DPI; otherwise your making a lot of pixels. There are some benchmarking techniques available to ensure your device can produce the resolution you expect. -Peter On Oct 13, 2004, at 2:03 PM, amalyah keshet wrote: At 23:04 12/10/2004, Tom Arnautovic wrote: Get the highest possible digital capture and go from there.

I second this. Don't get in the habit of keeping layered Tiffs around beyond the image processing / pre press stage.

Re: Standards for Digital Masters
As I said, surrogates, not masters. Masters are un-cropped, first acquired digital images. Any corrections to the original digital image makes it a surrogate. Color corrections are necessary once you start making reproductions of the masters for print or online display. Those copies of the masters should contain any adjustment layers, because you do not want to go back to the digital master to do adjustments every time you get a request for a reprint, etc. In any case, the archiving of digital anything is a never ending process. Be ready to keep on top of the digital imaging arena for the foreseeable future. Formats change, new ones get adopted, support for outdated formats seizes, etc. Technology advances do not rest. Hope this clarifies the situation.

Re: Standards for Digital Masters
You may also want to look at this site : http://www.scantips.com/ It details all the theory behind scanning, not only what can be done - but what a scanner cannot do. You may also want to look into software that gives you the flexibility to do what you need. We use a program called VueScan (http://www.hamrick.com/) which so far has done a stellar job, better than the software that comes with scanners. The one point that I can give - as outlined at scantips.com is that all scanning depends on the original. With prints (not negatives) scanning at anything higher than 300-600 dpi you get no more detail (simply because the detail is just not there). DPI higher than this is just scanning for size (i.e. to blow up the image). Once you really start getting into the theory and science behind scanning it gets complicated and you really need to know it all to get the best results. The times where you put the image on the scanner bed and hit scan should be over, it takes a lot of work to get a good digital representation of an analog work.

Re: Standards for Digital Masters
Hello Amy, I managed various digitization projects in the past 6 years, and a good rule of thumb is to push the limits of your digital acquisition hardware. We scanned a multitude of source material (lantern slides, nitrate negatives, positives, 35mm, etc., or over 60,000 objects) and do not limit yourself to any size, be it measured in pixels, Mega Bytes, DPI, MP, etc. Leave yourself some room ;) Get the highest possible digital capture and go from there. If your scanner maxes out @4000DPI, why bother scanning it at a lower resolution, or targeting a specific file size? You can always produce a smaller size, but if a larger one is necessary you have to go back and handle the media source once again to recapture it for a bigger output size. The bigger the file size (70MB - 250MB is not uncommon) the better. In other words, the bigger the file the more information on the object is captured. Also, focus on one master format, i.e. TIFF is a very common format in this regard (do not compress the files) and if you apply color corrections on surrogates of the original scan, place the adjustments on layers (yes, TIFF now supports layers), rather than flattening the image to save file space. Whew, that was a lot. Well, if you have any other questions, please ask.
