Photomicrographer James E. Hayden, RBP has been a consistent winner of the Small World competition for many years. Featured below is a photomicrograph of a arabidops seedling specimen taken with darkfield illumination with crossed red/blue filter.

Root Hairs on Cultured Arabidopsis Seedling Original Magnification: 46.7x Specimen: Unstained wet mount Technique: Darkfield with crossed red/blue filter

As with the image of a male roundworm and a down feather, 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). The main rootlet going in one direction with the root hairs projecting out about 90 degrees from the rootlet made this specimen ideal for this technique.
