How does APP know which flat to use
When combining data from different nights, I also have a number of different flat frames, one for each night. And sometimes, I even have multiple flat frames per night (when changing filters for example).
How does APP know which flat frames to use on which light? Can I somehow tell APP manually which calibration frames to use on which light?
Welcome to the APP forum 😉
Currently, you will need to calibrate the data per session and per filter and save these calibrated frames. Then you can process the data per channel by loading the calibrated light frames of all sessions.
On my priorities list, I have added support for full multi-channel and multi-session workflows. Basically, when this is added to APP, and you enable these functions, you will be able to tell APP to which channel and which session the calibration frames belong and APP will then process your data accordingly.
To have this working optimally, I intend to first upgrade the complete calibration engine. (smarter and with dark scaling). Then I'll start work for these functions. It's requested by a lot of photographers, so it has quite high priority 😉
So for now, you will need to calibrate the data and save the calibrated frames per channel and per session.
