Positioning techniques. A a glass plate is used to gently flatten a twisted tag prior to imaging (specimen UCM 61372 Uma paraphygas). Glass is undetectable in final images B the specimen (UCM 24543 Scincella assata assata) is positioned in the frame using the Helicon Remote ‘Live View’ function, and the scale bar and white balance card taped to the bottom of the tank are adjusted to closely border its body shape. These standards may be cropped out of final images if desired.
