In this case, it was a Q2 specific course and I wanted to learn about the functionality (especially the more technical functions) of my new Q (having come from a Nikon system which has a very different user interface).
I’m sure I would eventually learn many of these things through trial and error, but this was just very efficient and worth the cost because of the time it saved me. Also, the Leica user guide is really bad, so having a demonstration live of certain features was a great way to become familiar. Indeed, there are some helpful “hacks” I learned that are not mentioned in the guide.
Finally, if you look at the photo of the gentleman I took (who was the instructor) this shading is a technique I was working on with him. It takes some technical skill to take that kind of photo in a “street” environment, so I really enjoyed working on that.
