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 Formats change, new ones get adopted, support for outdated formats seizes, etc.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.

Tom, I would recommend against this; I assume you're referring to the layered TIFF that Photoshop (since v7) will output? These are virtually (if not completely) unsupported outside of Photoshop in some forms - they do keep a flattened version of the entire document for apps that don't support layers, but then you lose the main benefit (the layers)... but in my experience, the main benefit of layered TIFF from PSD is for using ZIP compression, which can really reduce the size of a complex layered document, and ZIP compression is also not well supported. In general, I wouldn't recommend keeping these as your masters, but they can be handy. PSD may be significantly larger for an equivalent layered file, but it's also much better supported, and understood - many folks still don't get that TIFF allows much more than a simple flat image. - R --- You are currently subscribed to mcn_mcn-l as: tarnauto...@cityofsacramento.org To unsubscribe send a blank email to leave-mcn_mcn-l-12800...@listserver.americaneagle.com --- You are currently subscribed to mcn_mcn-l as: rlancefi...@mail.wesleyan.edu To unsubscribe send a blank email to leave-mcn_mcn-l-12800...@listserver.americaneagle.com
