[Taxacom] Scale bar design when imaging herbarium sheets (Matt Buys)

[Arturo H. Ariño]

One suggestion is to include a grayscale/color reference. Costs nothing and
might be useful afterwards for image analysis. I'm posting our 2004 model as
a customizable ppt file at http://www.unav.es/unzyec/EscalaHerbario.ppt. We
printed it on a A4 photo paper sheet, cut and taped it to the inverted
scanner. It can also be placed on the sheet margins if using a camscan.
Regards, Arturo

We are in the process of designing new scale bars for inclusion on herbarium
sheets destined to be imaged.  A brief perusal of such images via Google
reveals a rather similar design being employed by the major herbaria, i.e. a
black background, with text and ruler markings in white, centimeters
designated by alternating black and white sections, the first centimeter
only subdivided into millimeters, etc. Is there a some kind of best practice
convention that is being followed?

Yours
