Actually, it took only about ten minutes or so...I simply used the color selector to capture the shade of color around the letters, then used that color with the airbrush...I'll admit there was some trial and error, since I couldn't find just the right tool to use until I settled on the airbrush. Incidentally, the spine on the Supplemental disc said 'Supplemental Materials,' while all of the rest of the artwork said said 'Supplemental Material,' so I found myself using the color selector and marking the added 's' in materials out with the inkpen tool (I also had to copy and paste the DVD logo on the very bottom of the supplemental spine). It was quite fun to customize my own set of covers.
Oh, and I've got all the files zipped together on my computer right now, including both supplemental covers. I'll stick them on my webspace this afternoon, and give you all a chance to download them if you want to. And also, I'll shortly be continuing my work on the inserts for the anamorphic versions...I'll be releasing those one at a time, it looks like, though, and it doesn't look like it'll take me too much longer to finish the ESB insert.
