How to tell the difference between sides of a filter

[chris_g]

Hello all,

While removing the L-eNhnce fitter from the camera rotator, I inadvertently unscrewed the filter itself from its two-inch ring. I can tell the difference in the sides by the color on each side along the edge, one side is yellow and the other is blue. Which side should face into the sensor?

Found an image showing the blue side to the threads on Amazon of all places. Would some one who has the filter be so kind as to confirm, it would be very much appreciated...

Hi Chris,

The blue ring on my L-eNhance is on the top if you place the filter on a table with the threads down.
So, when the filter is in my filter drawer the yellow side faces the camera sensor.

Thank you very much! I had put it in backwards! Some times I can be such a maroon,
