IQ3 Long exposure problem

[aleksandryants]

I have Iq380 and when I do long exposure I have a problem the right bottom side of the image looks Greener and darker. This only happens in log exposure mode.

Did anyone had the same problem?
Is there a way to fix it in post?

That looks like a sensor calibration issue. If so a dealer may be able to help send a calibration file or the back may need to go back to Phase One.

Nice shot also.

Is it possible to fix it in post? I am traveling right now and would not be abel to see the dealer as I am in Iceland?

I assume you are working in Capture Ine. If so you try applying an LCC if you have not done so already.  You could also create a local adjustment layer in C1 to work on that portion of the file. If you don't have an LCC you can still take one to use on this file or others.

This is a common issue for CCD. You could send it back to Phase One for re-calibration. It's not good at long exposure at all, especially when you compare it against a Nikon D810. The once-and-for-all solution is to switch to a CMOS back, e.g. IQ3 100MP.

As you are in the field, are you able to get a wifi connection?  If you can, I would attempt to reach out to your dealer and see if they can send you a new calibration file.  Certain problems can be fixed this way, however most of them are are tiling issues.  Your issue may not be possible to fix this way, (I hope it can be).   You also may want to try a back reset (you can do this in the field) and it will take you back to the base firmware the back shipped with.  Just a thought.

Not normal or acceptable performance.

Contact your dealer.

Hi,

The question is if it can be fixed in post? If yes, it is a naughty experience but rescue is available. If not, it is a really bad experience.

Best regards
