I got to tinkering around with the text on the original art buying pages today—for instance, the one for episode 36, page 57; just trying to clarify some small points, particularly that the lighting and colors in the photos I show on that page isn't as accurate as the color in the main, scanned versions of the art—the ones that appear as part of the comic itself, for instance.
My photo set up consists just of an old Canon PowerShot compact digital camera (they're so cute and tiny! : ) and my drawing table, and the lighting tends to come out either too yellowish or too bluish, depending on which of the bulbs in my drawing table lamps I turn on for the photo; in recent years I've erred toward the blue side of things because it looks less icky than the yellow. : P
So anyway, if you notice a difference in the colors between the cropped, scanned version of the art, and the photo version, where you can see it's sitting on my drawing table (a tip-off there is that you can see the edges of the artwork, and my messy drawing table paper cover behind it), the colors in the scanned version will be more reliable. : )
