Blur in B&W rendering

[Hervé]

Hi,

I'm quite disappointed about the B&W.

Usually, I put blue and cyan as black in roder to get a black sky.

The green and yellow are forced to white.

This works fine, Unfortunately, it seems that Affinity puts a blur on small details as tree leaves and grass. It is important because these details are the ones that are yellow and green.

 

When I use other tools, I do not have this level of blur.  

 

Thanks for help

Affinity will not blur anything unless you ask it to. How are you changing the colour ranges? Also if you post the original images and the output of the other tools then we will be able to help. If the images are too big to post then a DropBox link would be great.
