SX50 raw in auto mode?
AUTO cannot be used with RAW+JPG either (becasue it can't be used with RAW). You can also ask technical questions here: http://forums.usa.canon.com/t5/PowerShot/bd-p/powershot
You can down load the full Camera Users Guide PDF file (and it is searchable) here:
|Douaumont Ossuary by Eric 54-BNF|
from Armistice Day
|Silhouette at sunset by Jill Hancock|
from Portrait Lens (around 80mm or equivalent - please check the full rules)
