steve, tnx for the elaborate explanation.
i'll try to be more accurate,
i'm indeed shooting raw and importing everything to my LR catalog.
i'm going over to cut off unwanted images, like out of focus and other things.
than, what i do today is exporting full high res images and take it to the client. she brings me back her "picks" on a CD.
than i take the 300 images of what she burned on the CD and import them back to LR for final touch.
now i know it's not the right thing to do since once i export to the client jpeg's and import the clients selected ones back to LR i'm loosing the ability to work with my RAW files.
the thing here is this, no matter how the client does her picks, either checking off a list, writing down the numbers or just providing me with the files themselves, when i want to mark them in any way in LR (like flag them or just use a color label) i need to compare the clients "list" and check the images in my LR library manually!
what i want to do, is indeed export to email a low size copy of like 1500 images (so it would be light and easy for the client to work with), but in some way, and that is actually my question, when i get the picks back from the client, i would like to some how automate the labeling/flagging in LR according to the client picks.
