No problem. And yes, for lack of better words, Lightroom is a RAW converter. Calling it a RAW editor is more appropriate. Any software that lets you edit a RAW file will let you export or convert it to a more usable format, Lightroom, Photoshop, Canon's RAW editor, many others. I would look at something called a RAW converter as a program that takes a RAW file right off the camera and spits out a JPEG which then would negate the best part about shooting RAW which is editing it
Yes that sounds right on the file size. I actually edit my Public Affairs RAW's that are 21-meg then when I export drop them all the way to 900-kb for Facebook.
