You didn't post a SINGLE photo in class. I sure hope you're not telling people "I took Damien's Raw Class but it didn't help me". Of COURSE it didn't help you, you didn't post any photos.
Take the damn class again, and USE IT THIS TIME.
Perfect, thanks.
So Samsung screens have that stupid little joystick button on the back, and that's how you access the screen controls like brightness (and colour and stuff).
The button is described on page 10 of the manual.
