When I import a jpg of 3.4mb into Lightroom 4 on my Mac, it becomes 15.1 MB. Why?
I can't seem to find any import preferences, just settings that affect export preferences. What am I missing?
Thanks.

Are you importing it directly from the camera storage card?
If so then the camera may be compressing the files.

Compression is what you're missing, when you open up the jpeg in PS or LR you're getting the full size of the image, ie megabytes, RAW and Tiff are uncompressed Formats. . .

This one in particular, I received a jpg via email at 3.4mb. Imported into LR and it is now a 15.1mb jpg. Does this sound right? I had received an earlier low rez copy from the photographer and asked her for a high rez version, which she sent.
So, is LR performing an "uncompress" during this operation?
Thanks Dean and Reilly!
