1: it just adds and copies existing pixels with the digi zoom. I never fooled with it for you can just take the image with a paint program and blow it up as big as you want.. with decreasing detail.just start with a nice high megapixel like 5M camera but you'll need a bigger memory card.

2: exposure bias at 0.0 is what the camera sets as standard. adjusting this in the "M" mode allows more exposure "+" or less "-". making the aperture bigger or smaller to allow more light or less at higher shutter speeds or low speeds. 1/100 is good.
3: yes but try it out and put it on automatic first.
4: focal length or f stop I'm confused. The aperture setting is known as the f-stop. The lowest number f-stop lets the most amount of light reach the image sensor. A high f-stop increases the depth of the field.witch is focal length. so I think I was wrong in the "feet" meaning f/2.8 for portrait or up close f'/16 for front and background or landscape. also set your ISO around 80 - 120 for the best exposures or pictures.
