Make the bevel at the width where it will be at least a pixel wide for most of the time it's being viewed. Or, two pixels wide if you think it's not too comically wide up close.
One pixel hard and soft brush. Three pixel hard and soft brush. Master the brush options(opacity,tipshape,texture and scattering). I need nothing else.
Jocose: those squares in the rotor blades are 2x2 pixels, with a 1 pixel space in between. Hexagons aren't really possible due to technical limitations.
You probably want to get the difference of the values pixel-by-pixel using ddx, I think. Off the top of my head... for CG/HLSL; float heightmap = your height map value; float3 normal; normal.x = ddx(heightmap); normal.y = ddy(heightmap); normal.z = sqrt(1 - normal.x*normal.x - normal.y * normal.y); // Reconstruct z…
Silkypix doesn't have any lens correction yet. When Lightroom supports the x100, it will remove it, but it's not "quite a bit" it's already been measured by a few websites using grid charts and all the pixel peeper measurements, and it's very slight for a wide angle lens. Lightroom's lens correction features are great. It…
