### 1/5 — What do I do now?

*2012-01-18*

Picked up the application for color measurement and was happy to see it would provide Lab values.  However, I have tried several ways of calibrating and taking images to no avail.  I have calibrated with Color Checker and still can't get Lab values from images.
There are NO instructions for use or help of any kind.  Don't bother with the support link or the developer's website.
