Down Feather
Original Magnification: 39x
Specimen: Unstained dry mount
Technique: Darkfield with crossed red/blue filter
As with the image of a male roundworm and a arabidopsis seedling, this image was created with darkfield overlaid with a red and blue colored filter (see the male roundworm for a description of how the filter affects the image). Having a main feather shaft that projects in one direction with the barbules pointed outward made this specimen ideal for this technique.
