Lightbox

Mediterranean creatures on a lightbox

Today I put some tests on my cretean purchases from last September to evaluate their potential of being subject to fusion imaging. I bought three Nautilus shells and two sea snails, holding them in the store against the sun to check their transparency. My untidy studio accommodated these precious stones under quite a bunch of something.

The best representation is with a black background, i.e. with inverted L-channel in Lab colors. With a black background a soft shining light appears in the objects.

This snail has a shape a triangle and resembles a bear claw or an Apollo capsule in the late Sixties. The translucency is very little.

The following snail has a classic shape. With the black background it resembles a galaxy in outer space.

My first attempt with the Nautilus shells led me to a copper-like color representation with a single shot image. Lab colors is the key to this color and light distribution. Very attractive is the fact of two shells turning right and one left. Why did I wait so long to make this image ? Why do we miss important opportunities ?

I like to make things visible the naked eye isn't able to see. That's part of my profession as a radiologist, too.
