How often to dither.

#1

Post by starfield »

So I added dithering to my imaging routine this past weekend. It worked! Question I now have is how frequently should I dither? For a 2 or 3 minute sub, should I dither every frame? Every other? Every 3 frames? Curious what you'd all recommend.

Thanks. --Steve
