We wanted to try out our new macro lens, so I went digging in my sons box of …. stuff.
He assures me that what I found is a real Mosasaur tooth. That makes it between 82 and 65 million years old. This is the kind of fact that melts my brain if I think about it for too long.
He could be making it up, deliberately misleading me or just talking nonsense, but when it comes to Dinosaur facts he usually knows his stuff.
So, a Mosasaur tooth it is. Lets see what our new lens can make of it.
Here is our Mosy tooth. At 22mm high and dwarfed by a giant lego man, it made great subject to test our 1:1 macro lens.
The highlights on the glossy surface was also a good test for our cross-polarization set up.
These Pixapro Riko 400 ring flashes have become the go to tool for creating shadowless cross- polarized photos for making high quality photogrammetry. The polarizing film is held in place by a 3d printed mount.
This is the Sigma 105mm macro lens we purchased. Not the very latest iteration, but reputed to be sharp and distortion free at the small apertures needed for macro photography.
Let’s see what it can do.
And here is the result
The final result was produced entirely in Reality Capture before uploading to Sketchfab. The result is very impressive. Reality capture had no difficulty stitching all the images together with out any extra help. There is lots of nice surface detail and resolution. The final capture appears a little soft, probably because even at f16 the lens wasn’t able to maintain front to back sharpness on the subject in every angle. Next stop focus stacking.
Let us know what you think!
