Cat whiskers always show to be sharp when they are not


This tiny problem that I have may be a problem that can show up for others in other situations.

My cat's white whiskers always show up as being sharp even when they are very far from being sharp.

Without more details this sounds like it may be normal.  You don't say what you mean by "show up being sharp".  From my initial experimentation with the tool and from reading the manual there are two tools that help judge sharpness.  One is "contrast edges" and the other is "fine details".  The manual is quite clear in stating that "contrast edges" is not always a good indicator of sharpness.  From your description of "white whiskers" it sounds like you are using "contrast edges" to judge sharpness.  What do you see when you use "fine details"?

We discussed the issue in E-mail with posting starter.

The 'fine detail'  is suited well for printing (at 300-400dpi) or for screen viewing at 1/3 size at ~100dpi (so the initial image fills entire screen). If someone wants to enlarge the image much, one needs more 'fine' fine details filter.
