[UV, FL] Enhancing the visibility of fossil cephalopods soft tissue structures

I had the honor to work with Neal Larson (yeah, THAT Neal Larson who discovered SUE, the T-Rex, with his brother Peter) on a paper on fossilized cephalopods found in Hajoula, Lebanon. I used my remapping technology consisting of a visible image (A), a UV stimulated visible fluorescence image (B) to enhance the visibility of preserved soft tissue structures (C) by combining them into one multispectral image.

Should someone be interested in the paper, the full title is:

Another example of the same technique, shots I did with a squid fossil I have here from the Upper Cretaceous period, ca 90 million years old.

There is a follow up to this one HERE.

Stay tuned, more will follow on that fascinating subject...

UV helps to recover details of fossils

Today it is about fossils. Fossils and UV? Yes, since UV is not only able to resolve about 60% more details than a visual shot due to the shorter wavelength used, it also allows to extract more information by combining a visual and an UV shot into one using my remapping technique.

So lets see this on an example, here an about 100 Million year old squid. The lens used in that case was a calibrated for UV X90 lens plus my famous Baader U-filter (310-390nm) with perfect IR suppression.

I find it quite interesting that the remapped image reveals quite a bit more information now and due to the different colors helps to differentiate details of that fossilized squid much easier.

I have written about fossils previously HERE

So I hope you like it as much as I do....

Stay tuned, more will follow on that fascinating subject...
