Back Home — Rhododendron’s in Bloom.
.
My sister told me that she had coupled a Nikon TC-E 20 II (2x) teleconverter with a 105 mm f/2.8 VR macro lens and has been getting some good macro images. I thought that I had previously tried coupling a teleconverter with the 105 macro and that it didn’t work, but decided to try again. It worked. In this case a Nikon TC-E 20 III (2x) teleconverter with a 105 mm f/2.8 VR macro lens. When I got home after the ISE/SAA Enrichment Voyage to Central America and the Panama Canal I found the Rhododendrons around the house in bloom. To qualify, the only flowers were above level that the local deer could reach last winter.
.
I am going to need to do a test between the 105 mm f/2.8 VR macro lens with the 2x TC vs. the 200 mm f/4 macro lens.

Snow Plant.

Image taken 2 years ago today while driving through Yosemite National Park. I noticed something bright red in my rear view mirror. This was not red flashing lights, but rather something red in the woods. I turned around and found these flowers blooming. I did not know what they were — a plant or fungus. They were later identified as Snow Plants (Sarcodes sanguinea). Although plants, they do not use chlorophyll for photosynthesis, but rather get carbohydrates from coniferous trees via a shared mycorrhizal fungus.

Backyard Nature: Spring in New Jersey. 

I was afraid I was going to miss the Plum Tree in bloom this year. The tree took a lot of hits this winter and some significant cuts by the power company.  I also got an image of a new Maple Tree leaf.

First Daffodil Bloom and Other Early Flowers.

The first daffodil flower to open across the street. This location is facing west so gets the some extra warmth.
