First, there is the Screen Button on the left of the Electronic View Finder. This Screen Button offers a choice of two primary modes
Screen Button
A. Show SCP
B. Don't Show SCP
Info Button
1. Display SCP
2. Display Blank Backlit Semi Black Screen

Switch to Art Filter Mode on the PASM dial
Choose one of the Art Filters and confirm by pressing Ok
Now you have liveview using that Art Filter
If you want to swop to another Art Filter, press Ok and the catalogue of Art Filters will appear
If you want to adjust exposure, metering pattern etc... i.e. you want Super Control Panel, press Ok to display the catalogue of Art Filters then press INFO at that screen to display the SCP.

3. You want to adjust one parameter

With the top level menu facing you, press INFO (thanks to Tony Tulloch who relayed this from our other friends)
