Tethering With Nikon D810

[ianbarber]

Does anyone know of any tethering software which allows you to see the histogram live when the USB cable is attached to the camera?

I thought NX Tether would but only DSLRS it would cover are D6 and D780, not even my D850!!

Ah, if it doesnt work with your D850, not much hope for my D810.

Not possible AFAIK* for the Nikons as they don’t do live view over USB, and in general DSLR aren’t made to meter like that as unlike a mirrorless you don’t normally run the sensor continuously.


*I wrote some software for them once to interface over USB for a robot integration.

I have found some software which appears to be showing the Live Histogram using the Nikon D810. Ive just hooked it up and it is showing the Histogram but I am baffled as to how they are doing it because I have also read that Nikon does not send Histogram Live data over USB

Ah you can get live view off an 810:

gPhoto - Projects :: libgphoto2 :: supported cameras

They’ll be calculating histogram on that.

Is this documented somewhere?

Is what documented? Libgphoto or the camera APIs?

Camera API's

Ah, yes. Most of the manufacturers publish SDKs but behind license agreements that prevent resharing.

Nikon’s is here

It’s a while since I’ve used it though. You can often access for freee non commercially but I’ve not checked Nikon recently.
