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.
Hi,
i tried the long awaited feature to process DNG files from my Pentax K5 DSLR with APP 1.075 beta6, but anytime i got an Division by Zero Exception in the module MedianDPAapproachFilterDouble. The exception occurs in the calibrate module when processing darks and bias files and also in the star analyse module when processing lights.
kind regards from Düsseldorf/Germany

Dear Heiner @djones,
Thank you for sharing this issue.
Chances are the error is not related to APP's ability to process Adobe DNG frames, but due to an issue with your data. I did test the DNG conversion on a lot of Pentax camera models successfully.
I will be happy to sort this out quickly and have a look at your data. Can you upload the data that gives the problem including calibration data?
Which Adobe DNG converter version did you use? The most recent one?
You can upload the data here:

Make a directory with your name and upload some frames and I will have a look.
Thanks,

Hi Mabula,
thanks for your prompt response. As proposed i uploaded some sample pictures to your file station. These dng files came native from my Pentax K5. With Pentax there is no need for Adobe DNG Converter.
Hope, you can fix this
Kind regards
Heiner
Hi Heiner @djones,
Thank you very much for uploading your Pentax frames 😉
Indeed, there was an issue with the metadata that the Pentax camera stored in the DNG metadata. It's a bit different from how Adobe DNG converter would do it. But luckily, it was a minor issue, so I have fixed it and it will work in APP 1.075 which I will release tomorrow !
Kind regards,
Mabula
