The size of the image when being viewed in Loupe View is very small, with a checkered background.
Hard to say without more information.
- Only this photo or all photos?
- What type of image file is it - JPG, RAW, NEF, CR2, etc.?
- How did it get to Lightroom - Photoshop, Direct from Camera, etc.?
- Perhaps you can include a screen shot in your reply to this.
- What is the size of the file in MB and in pixels?
