UPDATE FROM MABULA

I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.

 

Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.

 

APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46.  Before I release it, I will make sure that everything is working properly and then I will release it.

Very nice.  My only critique is that it looks like blacks are clipped.

Maybe you're right... Where can i check the blacks? In the histogram?

Yes, you need to stretch so that data is not clipped when looking at the histogram, usually you then see a sudden sharp cut-off on the left side instead of a nicer curve.

Great image Gernot 😉 @skanker @vincent-mod @leuthold

Indeed, some of the blacks are clipped which you want to avoid.

Here is an example with and without Black Clipping, if you visually look at the image/data, sometimes it isn't that apparent, but the Histogram tells you what actually is happening, the Left Side of the Histogram needs to be near zero to prevent black-clipping anywhere in the image.

With Black Clipping, see left side of the Histogram:

Black Clipping Check LeftSide Histogram

Without Black CLipping, again, see left side of the Histogram:

No Black Clipping Check LeftSide Histogram

Cheers,

Mabula
