The owner of the shot wants actual product shots (in other words, each item in the store site is the actual item) for the clients, so that they receive exactly what they ordered, I don't believe he wants stock photos of the liquor. At least that is what I gleaned from the earlier posts.
Of course though if that is true, I would think a customer would be shocked that they receive a bottle with 2 stickers on the back, but the photo shows no stickers.
The owner has conflicting requirements.
= He wants the product as is
= He wants a photo of the bottle without the labels
= The labels cannot be removed for the photo shoot
= There has to be a white background
= There is no camera that can selectively make things invisible, whatever the light shows, the camera captures
= Photoshopping on such large label is nearly impossible, again, you break requirement 1, and you would have to "manufacture" liquid where you took out the label.
These are one of those things that is about 99% impossible to do. There is probably a way, but it would cost the owner more in time spent by the photographer (who is paid hourly) than what he will make on the sale.
This is like a car dealer hiring me to take shots of each vehicle he has for sale so he can have inventory shots so that customers know exactly what they are getting, but wants me to shoot them in a way that the dings and scratches don't show up. Preferably in-camera... because photoshopping means that the customer is not getting what they would see in person. Sure I could play tricks with lighting, but each shot will require specialized placement and settings, and that would blow out the costs of taking shots of used cars, where you do these more like an assembly line, run a car into the bay, shoot different angles, get lights into the interior and shoot, and move onto the next...
