If you want to be true to what you actually look like, yes 2 mirrors are required, but for self-portrait day and for my sake, it's not needed and not worth the effort to "reverse" myself that way because it's already challenging enough to study myself in the mirror. LOL. Nothing's stopping you though if you wanna go down this routine.DM, I used to have a mirror problem earier, but just recently I found one in a storage. I didn´t know we have extra mirror there so I´m happy. Of course I will do at least a color study from life. It just occurred to my mind that don´t we need two mirrors for one portrait?
