This image of Wallich's wood fern was taken in May, 2005. For a gardener's perspective on it, I'll direct you to Paghat's Garden. For (many) more photographs, have a look at the Hawaiian Ecosystems at Risk Project's native plants entry on Dryopteris wallichiana.
Like previous black and white images this month, I've used the Photoshop Calculations command. On this image, I combined the red and blue channels with screen at 100%, then the red and alpha1 channels using multiply at 85%. Since this probably means very little to you if you don't have Photoshop, I've uploaded the set of black and whites (red, blue and green channels, and the intermediary alpha1 channel) in one large image – you can see it here. At the very least, you'll see that there are a number of black and white manipulations that can be done to an image digitally; then again, many of the same manipulations were possible with film, depending on what film one used and what technique one used to develop it.
Botany / travel resource link: I believe someone mentioned this link on the garden's forums or the BPotD comments, but in case you missed it, check out Conifer Hunting in Mexico, a travelogue via the conifers.org site.

Bravo. When you look at the structure and texture the reduplication and selfsame similarity of the parts and replication of form one wonders what took us so long to come up with the concept of fractals?
Ferns are the ultimate natural fractals except perhaps coastlines and fossilshells and extinct Carboniferous plants and Mesozoic animals.
Ferns of course are living fossils nearly the oldest terrestrial vascular plants.
I enjoy the sight of this community of plants all clearly visible and visually differentiable and consumable.
