i’d been googling for answers for this, all guides point me to make it grayscale, but actually it is still not enough, it still allows non-black(gray gradient). What I want is
Suppose I ended up having this image: a perfectly round circle done via
ellipse tool
andstroke path
Then I want to make sure
if a pixel is not white then make it black
. So what I want should be like this:
I ended up learning the use of
sharpen
but it still not works, it just make the gray more black PLUS it adds more feather so even sharpen fails me to accomplish this.Hope somebody can help and guide me how to do this. Thanks~
Answer
You want the Threshold function. It lets you set a cutoff value, where all pixels lighter than that value become white, and all others become black.
The Threshold function can be found at Image>Adjustments>Threshold.
