Full Camera Resolution Crop - Thryallis
This page is about my "daylight" pictures and experiences with the Nikon D810A camera. I have a separate page about astrophotography with the D810A here. I have created a Yahoo Group dedicated to the D810A. Please check it out. Here's a review of the camera from the Luminous Landscape by Alan Dyer.
D810A with 200mm f4 lens at f14, 1/800s, Matrix metering, ISO 1000, auto white balance and Vivid setting. This is a straight crop of the camera jpeg, no editing.
Dragonfly Extreme Close-ups (Most with D810A)
I like it when I can catch some detail in the compound eyes of bugs. This a close up of a male Common Whitetail dragonfly. Nikon D810A camera, 200mm f4 macro lens, f10, 1/320s, ISO 800. Many of my 2015 dragonfly pictures were shot with the D810A.
This gal was hanging out on the front door. I used her to practice my macro techniques included use of the Nikon D810A's electronic front curtain, mirror-up, and delayed exposure features. This was 1/20s at f9, ISO 640, with the 200mm f4 lens. See more spiders here.
The colors were interesting on this one, but similar to the D750. D810a, 200mm f4 lens, f13, 1/640s, ISO 3200 (wow!) This one was cropped and re-sized; no sharpening.
