Lens Calibrator

This is a lens calibrator I co-designed with Jason Noack who is an amazing wildlife photographer. You can see his work on his [website](https://www.facebook.com/jasonnoackphotography/). You can find more information about lens calibration [here](https://expertphotography.com/lens-calibration/) among other places.

After you snap the pieces together as shown in the image, you will need to find a small ruler to lean in the same way the black ruler-like thing in the image is leaning (we didn't have a ruler handy when we took the picture). Then calibrate away!
