Nikon D810 exposure group failure

[Isphotoman]

Hello, can someone advise me why I can only take one exposure of a group containing more than one exposure  when shutter = Bulb  with my Nikon D810?? I tried the older 2015 initiation and the 2016 initiation, with the same result. I've also updated the firmware to the latest version.

Camera settings are as follows:  Dial set for a Single exposure, Menu  item Electronic Front Curtain Synch = on, Auto Focus off, ISO Manual. Note: I tried it with Electronic Front Curtain Synch set to off, it doesn't matter.

BYN  Exposure settings - 2 Exposures,  Shutter = Bulb, f1.4, 1 second, ISO 1600,  no pause, mirror  lock = 0.

When I initiate the exposure the display says 1 of 2, the image is taken, then I see Aborting flash briefly on the screen, then Busy flashes, then the first image is downloaded, then I get a windows error sound. End of sequence.

I tried multiple exposures with Shutter=1 second and all the exposures work fine, it just doesn't work on the Bulb setting.

Thanks

Claude

I found the problem! Thank you for advising me to reset the camera to the default settings, everything started working right away. I slowly enabled the desirable parameters and tested the BYN multiple exposures group function. When I turned on LENR the problem described in the original email showed up. So the problem is when LENR is turned ON; the first image in the sequence is taken, downloaded and the sequence then aborts. I tried to lengthen the BYN Pause parameter to allow for LENR processing but the problem still persisted. So using in-camera noise reduction is not possible at this time (: .    I suppose that is what stacking, dark frames, flat frames and all that other fun stuff is all about.

So thank you for helping find the issue.

do you have mirror lock enabled?

do you get an error message?

I have BYN mirror lock at 0, camera on Single Frame, D810 Electronic Front Current enabled in menu setup. It takes one image,  flashes busy / abort then I hear an alarm for each of the frames in the group. Then the image downloads. My camera firmware is not the most up to date would that make a difference?

How long an exposure? Bulb mode? Is any error message displayed? Shooting only RAW?

Try resetting the camera to factory setting.

IF this still does not work please send me the log files.

LENR cuts your productivity in half, if it works! You are correct that you are better off to take separate dark frames, at the same sensor temperature, ISO, and exposure as the light frames.
