There used to be a Photoshop plugin that would separate a full-color RGB/CMYK image into spot colors appropriately (or inappropriately, as the case may be) - for example, a predominantly tan and blue image of a person standing in water to just those spot colors. I think it made the images into DCS multichannel files ... anyway, is there anything like that for CS4? Or is there a relatively easy way to do it manually?
The Library of Congress uses the MrSID image compression format for many maps and other items available online. How can I get the full-resolution files, in whole, onto my mac so that I can edit/print them from photoshop? [more inside]
