A website that every Fujifilm photographer should know is: http://fujixweekly.com . On this website there are various Super Film simulations, which were developed by Ritchie Roesch. A small tip is to download the APP and the few dollars / Euros are money well spent.

|Film Simulation||Classic Chrome|
|Color Chrome Effect||Off|
|White Balance||6300K R:+6 B:+3|
