Backyard Summer Night Sky in New Jersey. Waxing Gibbous Moon. DSLR Night Video + Telephoto Lens Testing.

After several days having problem with taking video images of the moon with the Nikon D3s, I finally figured out what the problem was. I was pointed to a reference on the net about an undocumented feature in Live View that impacts video capture (Thanks to Howard Ignatius). The secret sauce is “use the OK button”

“- There is some misinformation online stating that the camera does not allow true manual control over ISO, shutter speed, and aperture in video mode. That is absolutely not true. The feature is undocumented for some reason, but if you hit the OK button while in live view, a light meter will appear and it switches to whatever mode that you currently have set on the camera (manual, aperture priority, etc). That means if you’re on manual, then you can adjust all of your settings as you please. Push the INFO button to cycle through different display modes, including a live histogram, horizon level, grid, etc.”  http://www.davidbergman.net/blog/how-to-get-manual-exposure-video-mode-on-the-nikon-d3s/

Bottom line, I now have manual control of the camera when taking videos!!!!!

The following video contains 15 second segments of the moon with different telephoto lenses comparing with and without the lens “vibration reduction” being enabled. When on tripod there is a difference. Let me know if you see the difference. The telephoto lenses and telescope used include the 600 mm f/4 VR, 600 mm f/4 VR + TC-E III 20 (1200 mm), 500 mm f/4 VR, 500 mm f/4 + TC-E III 20 (1000 mm), 400 mm f/2.8, 400 mm f/2.8 + TC-E III 20 (800 mm), 300 mm f/2.8, 300 mm f/2.8 + TC-E III 20 (600 mm), and Questar 3.5″ telescope (~1500 mm). The video was put together using Adobe CS5 Premiere Pro.

I’ve also included a still image of the waxing gibbous moon (97%) taken with the Nikon D3s and Questar 3.5″ telescope (ISO 1600, ~1500 mm, f/16, 1/1000 sec).

Backyard Summertime Night Sky over New Jersey.

Jet Transiting the Waxing Gibbous Moon. I am still having issues with the video mode automatic gain “feature” with the Nikon D3s. In doors with normal light levels it doesn’t seem to be that much of a problem. However, when trying to take video images of the moon through a telephoto lens, the moon is over-exposed. During the testing, I managed to catch a jet transiting in front of the moon. I happened very quickly (less than one second). The video below shows the transit  across the lower part of the moon 1) as is; 2) zoomed in from 100% to 250%; and 3) zoomed in at 250% and slowed down to 33% speed. There was also some cloud cover moving during the sequence.

I also took some still images of the moon with the same camera and lens, but with a TC-E III 20 teleconverter. The goal was to see how sharp an image of the moon I could get with a 1200 mm lens. Focusing was through “Live View”, and to minimize camera shake used the “mirror up” mode to allow the system to stabilize. The D3s allows the use of “Live View” and “mirror up” because “Live View” is now selected via a button on the back of the camera. You don’t have the ability to use “Live View” and “mirror up”. The first still image of the waxing gibbous moon at 92% illumination was taken at ISO 200, f/8, and 1/200 second. The second at ISO 200, f/16, and 1/50 second. If I did my calculations right for a 1200 mm lens on a FX sized sensor, the moon should only move ~0.2 pixels for a 1/50 second exposure.

Backyard Night Sky over New Jersey.

I think that this image of the waining gibbous moon with the D3x and 500 mm telephoto lens is sharper that the one I took with the D3x and 600 mm lens of the full moon 15-June-2001. Both were on a Gitzo tripod and Wimberley head, remote shutter, mirror up with 30 sec delay.

Backyard Springtime Night Sky over New Jersey.

We didn’t get to see the full lunar eclipse in this part of the world. The sky was clear, and the moon was bright so I got a chance to test taking images of the moon with my new 600 mm telephoto lens. The first five are attempting the same exposure while changing both aperture and shutter speed (f/16, 1/50 sec; f/11, 1/100 sec; f/8, 1/200 sec; f/5.6, 1/400 sec; and f/4, 1/800 sec). The final image was taken at 1200 mm using a TC-E III 20 teleconverter. For all of the images I used the camera autofocus, remote shutter, mirror up for a 30 second delay to allow the mirror up vibrations to decay, and tripod VR mode.

Saturday (30-April-2011) — Pacific Ocean

Gone to See Central America and the Panama Canal. Semester at Sea Spring 2011 Enrichment Voyage on the MV Explorer. Ultimate Travel Photography Workshop II with Michael Mariant. Day 4: At Sea.

Comparison of Digital Noise Reduction Programs. Pre-dawn view of the Moon, Venus (and Mercury) over the Pacific Ocean. Professor Ian Campbell had us look for the moon and several planets in close proximity. Here are a couple of images taken with a Nikon D3x and 85 mm f/1.4 lens (ISO 1600, 85 mm, f/1.4, 1/30 sec). I needed the high ISO to even get a 1/30 sec exposure since it was still dark and the ship was moving. For each image I processed with no digital noise reduction, then with either NIK Define 2.0 or Topaz DeNoise 5.0.
