Apr 9 2026 APP 2.0.0-beta40 has been released !
It has a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration, for mosaics even faster! We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. Improved Outlier Rejection with LN 2.0 rejection. macOS CMD+A works now in file chooser ! And more, all will be added to the release notes in the coming hours...
Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
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?
Hi Petra,
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.
Kind regards,
Mabula
You're most welcome Petra, let me know if the calibration works out like you expect for all of your data 😉
