2.37mb for a 600 x 409 pixel image is not right! I tried the steps with a RAW photo (*.CR2 from Canon 30D) and the original unedited TIFF file is 23.4MB, the 600X400 pixel TIFF is 735kB and the 600X400 pixel JPG is 160kB (quality level of 9).
I can't really think what is going wrong, but what you could do is open the RAW file, preferably in your camera's own software (Canon Digital photo professional, Nikon equivalent, etc) and save it as *.TIFF. This will result in a more general format lossless image. From there on you can do the editing. Save it under a new name, and only then resample it to another new filename but keep it as a TIFF file. Lastly, convert the 600*409 pixel TIFF file to a JPG file. Even though this is a very long procedure, this should at least show you where the problem lies.
What camera are you using? PS is not always very good at converting RAW images to TIFF files, but this does not sound like the problem though.
We must remember that a photograph can hold just as much as we put into it, and no one has ever approached the full possibilities of the medium - Ansel Adams
