Here's the trick that makes IR anomalies visible: Put a black E-6 slide over the lens of a night-vision device such as the ATN-Viper.

Now I see scenes in broad daylight similar to how they appear in infrared black and white prints.

I am really enjoying this view of the world. Live IR!

And I see the extreme examples I was looking for.

Looking through the infrared viewer, foliage in shade is as bright as foliage in the sun. So I am focusing my attention on shaded foliage.

Adding the red meter over the Sekonic only reduces the reading of green foliage in shade by one stop.

By carefully choosing an edge case, I have found a problem that could lead to a two stop underexposure.

Solution: Meter without filter and apply filter factor afterwards.

I think I will bring the night-vision device in the field to help me see how much infrared is in my scenes.

Who am I kidding. I'm bringing the ATN-Viper to have fun.
