Beijing Swarow wedding photography, before filming, can I send the selected film through QQ?

This is definitely impossible. Every studio is very strict in the management of negatives. After selecting the film, you can ask the film selection staff to make some copies for you. But now that you have chosen, you must only take the film when you take it, but if you have acquaintances on that set, that's fine. You can ask them to help you operate.
