Motion blur, diffraction and noise are not impacted by high megapixel count

In today’s guest post, Jinn Leong is explaining why  Motion blur, diffraction and noise are not impacted by high megapixel count (in our case the Nikon D800):

Diffraction
Diffraction depends on the lens, not the sensor. A higher megapixel count won’t increase diffraction. There’s a common misconception that a higher megapixel count increases diffraction because most of the time, images are examined at 100%. If you normalized the images from two cameras with the same lens to the same pixel count/print size, you’ll realize that both of the images have the same amount of diffraction.

Motion blur
Motion blur depends on the field of view. So, a higher megapixel count won’t increase motion blur. Of course, at 100% magnification, motion blur is more visible. If both are displayed at the same size, there will not be more motion blur.

Nikon in space: new NightPod intelligent tripod compensates for motion when taking images from space

Credit: ESA/NASA

The European Space Agency published the article “Tracking cities at night from the Space Station” where they describe a new NightPOD intelligent tripod head used to take long exposure photographs by eliminating the motion blur from the International Space Station:

“To help astronauts take better pictures, ESA developed a motorized tripod in collaboration with Dutch company Cosine. Called NightPod, this device compensates for the motion of the Space Station by tracking single points on Earth automatically. The subject stays centered in frame so the final image is in focus.

Astronauts enter data regarding the Station’s orbit and attitude and then NightPod can start taking pictures. It can even be set to run on its own for up to six hours.”

Nikon D800 locks up?

Can you spot the problem?

I have noticed that the Nikon D800 locks up and the only way to reset it is to take the battery out. This happened to me several times while shooting with different lenses. Has anyone experienced this issue? I have not seen this problem being mentioned anywhere online.
