An Anisoptera exuvia was collected by Freda van den Broek on 10 June 2019 along the St. Croix River in Polk County, Wisconsin USA.

This specimen is definitely a member of Family Gomphidae (Clubtails), probably Mustached Clubtail (Hylogomphus adelphus).

Tech Tips

This subject was photographed against a pure white background (255, 255, 255) using the “Meet Your Neighbours” (MYN) technique. This photo is a “one-off,” that is, not a composite image.

Eight (8) photos of the specimen were taken using an aperture of f/16; in-camera focus peaking was used to highlight select areas in each photo. Adobe Photoshop CC 2017 will be used to create a focus-stacked composite image of the exuvia.

HDR panorama composite image of Hollin Hall

The following panorama photo of Hollin Hall is a composite of six overlapping photorealistic HDR images.

Tech Tips: I used my Panasonic Lumix DMC-FZ150 superzoom camera, Adobe Photoshop CS5, and Lightroom 4 to create a panoramic of six overlapping 16-bit HDR images; each HDR is a composite image created from three bracketed exposures, +/- 2 stops of exposure. Photoshop was used to create the HDR images and merge them into a panoramic; the resulting image was adjusted using Lightroom 4.
