Testing 1, 2, 3…

January 26, 2016

The following photos were taken on 21 December 2015 at Huntley Meadows Park while field-testing a new Nissin i40 external flash unit with my Fujifilm X-T1 mirrorless digital camera and 55-200mm zoom lens (88-320mm, 35mm equivalent). The camera was set for “Forced Flash”: “Flash On, Fired” appears in the EXIF information for all shots.

The camera was set for Manual Mode: both Aperture and Shutter Speed were operator-selected; ISO was set to “Auto.” Notice the camera used ISO 800 for every shot. One obvious advantage of using a digital camera featuring a larger sensor — in this case, an APS-C sensor — is the camera can shoot relatively noise-free photos at higher ISOs.

Also notice the rich color in each photo, something for which the Fujifilm X-series of cameras is well-known.

Unknown blue-black berries. Alonso Abugattas, moderator of the “Capital Naturalist” Facebook group, speculates this is probably a species of greenbrier (Smilax sp.).

Crimsoneyed Rosemallow (Hibiscus moscheutos)

February 6, 2015

Crimsoneyed Rosemallow (Hibiscus moscheutos), shown below, is another flowering plant that is widespread throughout the hemi-marsh at Huntley Meadows Park. More commonly known as either “mallow” or “marsh mallow,” Crimsoneyed Rosemallow is one of ~300 species of plants in the genus Hibiscus.

The small insect shown in the preceding photo is a Spotted Cucumber Beetle (Diabrotica undecimpunctata), “a major agricultural pest insect of North America.”

During “Huntley Meadows Park at Night,” a class/walk-and-talk led by park naturalists P.J. Dunn and Matt Ryan on 19 July 2014, I was surprised to discover Crimsoneyed Rosemallow flowers close at night.
