The actual rule is
In the expanded text under that rule is
Studies from photos ARE allowed
so this is fine :)
I had to stare at the comparison pic for a sec to wok out which one the photo was x_x so I showed it to my sister with the only context being "photo study" and she was like "which one was the photo" before being annoyed about how good you are XD
Ahh! Thank you for clearing that up! That's good news
Thank you very much to your sister, and to you! Very kind of you both :)
