May 27 2026 APP 2.0.0-beta45 has been released !

Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.

Apr 14 2026: Google Pay, Apple Pay & WeChat Pay added as payment options

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.

 

HSL Selective Color giving bizarre results

I cannot get HSL Selective Color to work at all for me. No matter how small an adjustment I make, it makes huge, unusable adjustments.

Example, here's an image that I start with.

APP before

I then select GREEN color, and make the smallest possible adjustment to the B<->YE slider, setting it to -0.01. Here's the result:

APP after

I tried this on two different computers, with two different versions of APP (1.070 and 1.064)

Help!

Kross,

are you processing NB data and are you trying to take the green cast out?

Sorry. Forgot to add a link. If you ARE doing NB and trying to rid the green coverage for Hubble pallet coloring (you probably are already doing this anyway), when you are in RGB combine, you set OIII and SII to green channel along with Ha. Use the multiplier sliders to adjust even more (sliders on very top of the channel settings). Increase OIII and SII multipliers to offset. You can use selective color later to sharpen colors.

If none of this applies, then disregard. Was just trying to help.

See Mabula's video on Vimeo. Specfically covers this around the 24:00 mark.

Hi Kevin  @kross,

Yes, the information in your screenshots woudl indicate that something strange happens with your data. Could you send me the particular file so I can have a look?

The minor adjustment that you do, should really not be visible as a change.

Kind regards,

Mabula
