Anyone know how a D200 records time? It has RXIF tags, two are Date/Time Original and Sub Sec Time. Apparently the time is recorded but split between those two? So the fractional second is in Sub ...

Oh, I read the EXIF data all the time. Image number is 7811 but I had not really looked at that before.

The D200 is still a solid camera, I use mine all the time to take photos of satellites at night. I will have to look around and figure how to get the shutter count.

Let me "oops" my reply! After trying the test several times I realized that I had not read this above note - I had wondered why the app looked different. This is sadly not the first time I have ...

That has been very illuminating (photography humor). A "5" second exposure is 2.5 seconds long! A "10" second exposure is about 5.1 seconds long!! So I can just cut the displayed exposure time in ...

That is a great idea, let me try it (tomorrow). I'll report back.

Yes you would think that since the camera can take exposures at 1/1000 of a second it could measure exposure time that accurately. I get photos of satellites and generate (through a long and ...

All - After solving several other difficult questions, now another one comes up. I have a Nikon D200 and use it to take photos of satellites, using mostly 10 second exposures. But it appears that ...

The first is a satellite but the second does NOT have the red and green lights typical of an aircraft in flight. Maybe it is a far away contrail.

I have been tracking satellites since Oct 2019 with my Nikon D200 and it is great. After starting with lots of questions about that process I have been slowly answering each one - the next in the ...

Another problem solved, the open command in the bash script works great. So the script submits 4 or so photos to a site that "resolves" them and then JEXIFToolGui starts so I can get the exposure ...

Wow! Two excellent and helpful replies! I would prefer to open the GUI version since I feel more comfortable seeing the image, to double check my workflow. I only need the time of shutter (in this ...

Ok this is a niche question. I take photos of satellites (yes at night) and submit them to an astrometry site to "resolve" them. This allows me to use the photos to generate observations so a group ...

I got pyexiftoolgui and put it into Applications - it cannot find EXIFTool. Grrrr. I use a Python script to put photos into an astrometry site so I know that I have a good Python installation. I ...

All - Yes I have EXIFTool and paid for the application, but I'd like to try a GUI application. I have a MacBook Pro and a Mini and would like to get an EXIF viewer from the App Store. Most of the ...
