Nail your white balance first time.
I used the previous version for years and it saved me so much time that it's paid for itself many times over. This newer version is actually cheaper than the previous version by a few pounds and it comes complete with a handy case to protect it. It's 82mm filter thread size is perfect for all the lenses that I own, it's simple and easy to use as you can capture the WB one of two ways. Both ways you put it in front of the lens and you capture an image and use this to set your WB when editing. The second way is to set a custom WB in camera via the settings of your camera. You can also use it the same ways with flash photography.

Stuck step-ring
Attached the Expodisc to the Step-ring. No way will it come off, so it's going back.
