what is the difference LCD on a Digital Compact Camera and TTL?
• The LCD on a digital compact camera shows in real time what is projected onto the sensor by the lens and therefore avoids the above parallax errors. This is also called “TTL” or “Through-The-Lens” viewing. Using the LCD for framing will shorten battery life and it may be difficult to frame accurately in very bright sunlight conditions, in which case you will have to resort to the optical or electronic viewfinder (see below).
