The new version not only allows you to document your own lighting setups, but also has a built-in library of setups I used for some of my photo shoots, with detailed settings and notes, available for in-app purchase. If you want to learn professional lighting that was used in actual commercial and editorial shoots, this new addition to the app might be exactly what you are looking for, whether your are just starting or you are already a working professional.
Please note that this version of the app requires iOS 8.1.
As always, I look forward to your feedback. If you would like me to add any other lighting setups, that you can see in my portfolio, to this library, please send me a link to a photo from that particular shoot.
