How can GIMP's Blur Tool blur way more swiftly, effectually?
Apprise me if you know better examples. I trust obvious what boundary I'm trying to Blur — the two different hues of grass or water. And the forehead with the bad haircut, because the hair cut off too abruptly.
If you want to use the blur tool: you can try to increase the "Force" in the Tool options and/or use a harder brush. You don't need to click hundreds of times, just depress the left mouse button and wiggle the mouse over the cut.
I tried this wiggling for the past ten minutes, but the boundary blurs too little and slowly! All this wiggling's WEARYING and FATIGUING my hand!!! I need the Blur tool to work more forcefully, expeditiously, nimbly!
What if I increase the tool size to cover the whole borderline? Aim my mouse so that I cover the whole border. Then depress my mouse and keeping it at the same spot, without any budging or wiggling?
Pls review my settings for the Blur tool? I turned up Force to 100 as xenoid advised, but did I overlook anything else?
