Photoshop keeps the original RAW data also, even if you burn the file
after preparing the interpretation in Adobe Camera RAW.
All I recommend is doing your conversion and saving as a tif. Then
compress your tif with jpeg compression for easy emailing. Of
course, there will be some loss due to the jpegging, but once is not
likely to be devastating to many color files.
If you are a new Adobe Camera RAW user I strongly recommend that you
carefully explore all the items in the menu bar in the browser
window. There are items there specific to RAW conversion which are
not in the Photoshop menu bar. These items contain many of the
powerful features of Adobe Camera RAW.
