But filters are resource hungry. As I tried an application, I had consistent lags between my strokes.
I just wish there was a more efficient and covenient way to do this.
Now where did I get this idea ?
I got it by sing CSP.
Apprently, rather than color space/color depth, they just provide a “color expression” setting which supports three modes : color, gray and monochrome.
I was interested in the monochrome one. It didn’t seem like a filter in the app and drawing with this mode is butter fast, even though I use an old laptop.
In the layer properties, there’s an integrated toning mode(only with gray though).
And this toning mode is achievable in Krita using the way you’ve shown earlier.
But filter or not, Clip Studio apparently, computes graphics elements faster than Krita.
Creation of a new file is faster, brush strokes are also faster, etc.
I just suspect it’s because they’re in advance regarding integration of an interface that targets GPU mostly for graphic elements, on the canvas at least.
Anyway. There are workarounds.
My final resolution was to use a brush with sharpness modifier to fake it.
The result is close enough.
