So I fixed the problem by suspending the pill bottles on a thin piece of glass over the blue screen and shooting them straight on. This totally reduced the spillage on the bottle and gave me a clean key. all I had to do was crop the bottom up to get rid of the glass. As I was shooting straight on it was no problem to crop to the bottom of the pill bottles.
For other shots with the pills laying in front of the bottle, bottles, I just shot down on them at a higher angle with no keying… I used natural settings as well as a product photo tent that I purchased with great results…
Thanks for all your help…
