Hi, I am looking for a good collection of reference portrait photos. It looks like others are using Proko model photos but I cannot find them. Are they available for subscribers to this course?

Hi Mikhail In the fourth video at about 1620 you describe how to make highlights, with tinting with a small amount of glue. What does this mean? Could you describe more in detail what you are using and what you are doing? What is tinting? Is it a substance? thanks, Steve Saxenian
