I found my camera.
I got a couple of NARS duo eyeshadows, which arrived this morning. The two eyeshadows on the right of this first picture are the Jardin Perdu duo, and the picture doesn't do them justice - they are absolutely beautiful, and this is with one swipe, applied with my fingers.
Here they are again, and the duo on the left is Tropical Princess - again, well pigmented and just one swipe.
This is Estée Lauder Arctic Sky on the left, and Urban Decay Divebar on the right. It's difficult to capture the duochrome on both at the same time, but I think you can see from this that the pinky bit is virtually identical.
