6. TYPES OF CAMERA
Reflex or SLR camera
SLR cameras allow for a
shallower depth of field,
a greater range of
subject styles and thepotential for higher
image quality
Compact camera
Compact cameras are
much smaller, lighter, less
expensive and less
conspicuous, but areprobably better for
learning photography,
since they cost less,
simplify the shooting
process and are a good
all-around option for
capturing many types of
scenes out of the box.

7. HOW IS IT USED?
When light waves enter a piece of glassat an angle, one part of the wave willreach the glass before another and sowill start slowing down first.
The effect on light is the same as it entersthe glass at an angle, it bends in one
direction. In a standard converging, orconvex lens, one or both sides of theglass curves out. In a double convexlens, such as a magnifying glass, the lightwill bend when it exits as well as when itenters.
This effectively reverses the path of lightfrom an object. A converging lens takesthose rays and redirects them so theyare all converging back to one point. Atthe point where the rays converge, youget a real image of the candle
