Just got a panasonic lumix TZ8 - looking forward to trying it out. It has an all singing / dancing idiots mode but it also has a shutter priority mode which sets the aperture according to the shutter speed I set, and an aperture priority mode which sets the shutter speed according to the aperture I set.
What do these mean? What benefits to my photos will I see? And what settings would give me a nice portrait shot with that sort of soft background
any good beginners links gratefully received
