You can't even begin to compare those 2 pictures. One is outside on a seemingly cloudy day, with no flash. The others are in a enclosed space with natural lighting and a flash.
To compare, you would have to have the exact same picture with 2 different cameras.
Usually just a wash with turtle wax wash, zaino Z-2, and mothers wax. But those pics are each after just wash and about 1 month from polishing/waxing.....soon I'll get some Klasse and P21S carnauba wax.
