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.

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

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

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
