Why are the thumbnail and panorama editor images so blurry?
PTMac uses reduced size images for the warped image preview and in the panorama editor window. The scale of the thumbnail images had to be reduced to gain acceptable performance on older computers. You can change the scale of images used for the editor window via the pop-up in the lower left corner of the editor window. You can choose one of the pre-selected options or enter your preference via the custom setting.
