Prior to importing photo's should the thumbnails be of a low quality such that they are blurry?
I have recently started to use lightroom and when selecting a folder to import from my hard drive the thumbnails are of (in my opinion) very low quality. Once they are imported they are fine, is this correct?
The import dialog is there to help you locate And identify the images that you want to import. They are not high quality previews. You shouldn't consider using the import dialog to determine the quality of any image. Use it to identify your images and get them imported. Then let Lightroom generate its own previews.
