Hello,
Iam struggling with an exercise which includes High Pass filter. When using the filter the image turns gray. The next step is to change the layer blending mode to Overlay which makes the gray invisible and reveals the sharpening effect. How come the Overlay blending mode makes the gray disappear? I have also seen somewhere that 50% gray is Overlay neutral color. I do not grasp this Overlay versus gray stuff, can someone please explain it to me?
Thank You,
Martti
