Hi Brian, is the first image that you attached the image you're using?

That image is only 687 by 480 pixels in size, which is pretty low resolution, with an image of a low pixel density like that each pixel will end up being kind of large on the MoI viewport and the bilinear blending effect will be exaggerated.

Are you cropping out a small area of the scan to get this particular image? If you want it to be clearer it just has to be higher resolution, if there are more pixels in the image the individual pixels will not stretch out to as large of an area in the MoI viewport.

It can be problematic to have images that are excessively large as well but you would probably want to shoot for something more in the 1500 or 2000 pixels in width and height to get a better viewport display of it.
