I've always found it very time consuming to get the perfect white background isolation even when I shot the object with a white background. But I've found a great instructional video online that will go over two simple steps to get the "perfect" white background as well as a method to check if your background is pure white. If you have been having troubles with this, the video is a MUST SEE. It is so easy and quick, I want to actually check my current photos and possibly resubmit them. Definitely I will try to take some more white background isolation photos with this technique.
I hope this will be useful to everyone.
