I don't understand your answer ?
The Picture that is shown in focal blade is only 4.5 " x 4.5" max. In a small or large image this reduction is major. I can't see any real detail of the sharpening until I apply it to the image and look at it in Photoshop.
When focal blade is completely covering my monitor the center section shows the image I'm working on, that is what I'm talking about. I would like to enlarge 1/4 of that square to full size of this preview section.
When I'm working on a complete image this is to small to see the fine details that I need to see.
