Are you asking about Lightroom?
How do you "do editing on a photo" ? What program?
Where do you "click import"? Is that in Lightroom?
Where are you expecting to "save any of the work"?
Are your "dull" pictures JPG or raw (NEF, CR2, etc)?
What and where are your originals?
If this is Lightroom you are talking about (is it?), you shouldn't edit a photo and then later click on "import". You don't need to import the photo to see your edits.
Can you explain your workflow in a lot more detail?
