The film type is just an indicator of how many posts you have on the forum, not your preferred format. It will change automatically.
There is some confusion about the color and number of cameras. I think it has to do with a complex formula involving posting frequency, relative humidity, offset from GMT, and the age of the oldest film in your freezer. We have all been trained to ignore the camera icons and just treat everyone like they are a long lost friend or acquaintance.
