I'm starting to learning pixel art and I have doubts.
My idea is do something like this:
The pixel is perfectly defined. I'm trying to do this in Photoshop and I cannot do it unless point by point with the pencil set to 1 px square. But I want to do, for example, a perfect pixel art circumference with the ellipse tool, and I have this:
The pixel is not definted with the perfect white. It creates shadows and lights.
With Filter > Pixelation > Mosaic happens the same; not perfect defined and contrasted pixelation, but with shadows and lights.
What do you recommend me? Use another software to create pixelart? Use a different process in Photoshop?
