Was just messing around and hit negative on a coin with desert patina and thought it looked pretty cool and wanted to share.
Yeah, when I looked at the pics first, I thougth he was posting a die used for both siliqua and AE3's until I read the message. Lol.
Going negative makes the 'siliqua' look like it was lighted from below so I'd suggest actually lighting from below and see if it looks more like a normal photo. That leaves only the white shadow problem so you could shoot on black so the background goes shadow free. That only leaves the question of why you want a fake siliqua picture butI suppose you could show it to an 'expert' and see if he can figure out he is being joshed.
