Jasem and Jantje:

I have a Nikon D750 and I can assure you absolutely everything works fine. I've put in attachment some screen copies with my settings, if this helps.

On one screen, you can see a red dot facing the definition, this is normal. The screen copy was taken after I used the live stream, so the definition is that of the rear screen.
When you take still images, the definition returns to 6016x4016 and the red dot goes green again.

Jantje, for your third problem (the connection) look for a file /usr/lib/udev/rules.d/99-nikon.rules. it should contain ...

<

---

ACTION=="add", ATTR{idVendor}=="04b0", RUN+="/bin/sh -c '/bin/echo 256 >/sys/module/usbcore/parameters/usbfs_memory_mb'"
SUBSYSTEMS=="usb", ATTR{idVendor}=="04b0", MODE="0666"

---

>

... so every one can read and write the device.

The same directory should also contain a 85-disable-dslr-automount.rules with ...

<

---

# Disable automount by setting envrionment variable for UDISK2.

# Pentax
SUBSYSTEMS=="usb", ATTRS{idVendor}=="25fb", ENV{UDISKS_AUTO}="0"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0a17", ENV{UDISKS_AUTO}="0"

# Canon
SUBSYSTEMS=="usb", ATTRS{idVendor}=="04a9", ENV{UDISKS_AUTO}="0"

# Nikon
SUBSYSTEMS=="usb", ATTRS{idVendor}=="04b0", ENV{UDISKS_AUTO}="0"

# Sony
SUBSYSTEMS=="usb", ATTRS{idVendor}=="054c", ENV{UDISKS_AUTO}="0"

... so the device won't be set "busy" when the driver tries to access it.


Jasem, I also have a D3100; it works fine except for the live video, which is not supposed to. The D3100 in a low end Nikon, so it isn't as feature-rich as the high end cameras like the D500 or the D750. Being from the same bloodline, I wouldn't be surprised should your D3500 have the same problem. But I repeat, everything else works fine.

In the live video, it you click the debayer, everything goes boom.

Well, I hope all this helps

I do not use Nikon myself, but I got reports on Nikon D7500 - apparently file format selection is not working properly and whatever you do, you end up with jpeg-fine format. It looks like this behavior id model dependent and is related to libgphoto2 rather than indi driver

@Marc2b - thank you for your support - I am currently shooting with the ZWO ASI294MC PRO and it works perfectly, but if I have more time I will try again with my Nikon D500.

Hi Radek

Yes, I can verify that. I have the D7500 and also the D7000 and D750. The 7000 and 750 have no problems: FITS are NEF both save fine upon selection. The D7500 switches to jpeg when RAW is selected. But it actually save FITS just fine.

Hi,
I can confirm the same behavior with the latest Stellarmate (1.4.6) and also with my own MATE based stack which I compiled about a month and a half ago using github versions of INDI but mostly bionic sources for other libraries. It ignores the capture format setting and leaves the camera to FINE after you have unplugged it. Preview and saved image comes as JPEG unless you chose FITS.

In fact FITS doesn't exactly work fine either. It has 8 bits per channel.

Clearly something with that model.

ASIAIR works correctly though and I believe it too has INDI under the hood. However, ASIAIR does not touch the format at all. I know this because it will stick with whatever I have chosen on the camera. So perhaps it is just the "set format" operation that is flawed and a possible workaround would be to disable it completely and just use what the camera has? I will try to see if that is feasible.

Hello Dimitris & welcome to INDI forum.

So I took a look again at the driver code and found this tidbit in gphoto_driver.cpp:1058

So it could be here that this is failing for some Nikon models? Can some comment out this code block and compile again? If it was indeed proven to be the culprit, we can figure out a way to add an exception for the affected Nikon models.

Jasem, this is the same issue I reported to you about 2 months ago with the D7500 where it would switch to JPG fine, which prompted you to get the D3400 for testing.

I found that using NEF + JPEG normal in the camera would enable it to save as NEF. Selecting just NEF would result in it switching back to just JPG fine being saved to the SD card in the camera.

The setting in the INDI control panel would reflect very odd characters.

What's the VID:PID of D7500? I think I found the issue in libgphoto2 and working on a fix.

Where do I find this information?

On Linux: plug it in, open a terminal and type lsusb
On Mac: click the Apple to the top left -> About This Mac -> System Report -> USB

Thanks, I've pushed a possible fix for this to my own libghoto2 fork here: github.com/knro/libgphoto2

So this requires some knowledge in compiling as this must be compiled and installed first, then indi-gphoto is compiled afterwards and tested. If there is Teamviewer, I can do this remotely.
