I am trying to have a brush like the one on the left (Paint.net). I have tried everything I could, but I can't make it rougher in Photoshop (right side of the picture). As you can see the Paint.net brush is a lot less transparent and more rough, thus producing more blackness then the one in Photoshop.
Any way to adjust the one in Photoshop to look like the one in Paint.net? It's basically the default Paintbrush at size 1 in Paint.net.
