Following are my personal take-outs from this discovery;
-
I have found (according to my liking) that output using the standard Bicubic algorithm is much too soft/mushy … hence, I’ve always used Bicubic Sharper.
-
Generally, I am happy with the results using Bicubic Sharper … but I have noticed examples where the result was too sharp for my liking (particularly with certain tree foliage) … I now have a solution to this problem;
- As a result of experimenting with a range of settings (starting with the OP’s suggestion of 32), I found that “Degree of Sharpness” = 45 works best for me.
- I can leverage the knowledge that this setting has no impact on the Bicubic Sharper algorithm …
-
I have updated my user.config file (see instructions above) to set “Degree of Sharpness” = 45 … and future PL updates will copy this setting forward
-
I will continue to use the Bicubic Sharper algorithm as my default interpolation algorithm
-
For cases where I find the result too sharp, I can switch to using the Bicubic (not Sharper) algorithm … and it will apply my choice of “Degree of Sharpness” = 45
There have been long-standing requests to make the degree of sharpening configurable for exports … I will raise a ticket with DxO Support to request that this setting be exposed to the various “Export To …” dialogues.
