Hello, thanks for the answer.
I’m doing the certification program. I guess you are talking about capturing the texture of the material?
An important point that you mentioned: styling and composition. I’m sure I’m not the only photographer who would be interested in a course about that. Although that’s quite a different job, it can definitely help photographers that work alone. I also heard Alex saying that he was not good at it, but maybe he could be good at finding the right persons to make a whole course on that? The goal wouldn’t be to become a master in that field, but know enough when you have to work alone.
That could be styling / composition for jewelery/clothing/food/etc… photography.
Have a nice day.
