[quote]QUOTE: Can someone explain all the tech lingo on aperture size and exposure time to me? That would be a big help. [/quote] Smaller apertures give greater depth of focus. Aperture and exposure time (shutter speed) are linked together. Make the aperture smaller, and the exposure time has to be longer to allow in more light. Think of a water pipe as an analogy: If a one inch diameter pipe will need one second to fill a bucket, then a half inch diameter pipe will need four seconds to fill the same bucket. A one inch hole is four times larger than a half inch one; think about it. Similarly a quarter inch pipe will take four times longer than a half inch pipe - 16 seconds. Clear as mud? Hope so! This is the way aperture and shutter speeds work - increase one, decrease the other. Decrease one, increase the other. Each lens opening (aperture) number is one quarter the size of the previous higher one. This shouldn't reall be a great concern, as most modern cameras will do the figuring for you. The big problem with most point and shoot digital cameras is their aperture will only stop down to around f/8. You need f/16 or f/22 for maximum depth of focus. Usually these smaller apertures can only be achieved with DSLR cameras - Digital Slingle Lens Reflex models. These come with removable lenses and are of course in the expensive line. My Canon Digital Rebel is such a DSLR, as is the Nikon D70. Ask away! Bob Boudreau
