It's been a while, but Bryan must talk about the "exposure triangle" in that book, no? There are 3 settings you can change to obtain a correct exposure with a set amount of light, your aperture, shutter speed and ISO. Adjusting each one changes something about the final photo, good or bad - whether it's the amount of motion in the photo (shutter speed), the depth of field (aperture), or the amount of noise (ISO).
If you would like more DOF but can't slow your shutter speed down anymore, and don't want to increase your ISO, you need to add more light.
Yes, Bryan does talk about the exposure triangle - in fact, he covers it very thoroughly. It sounds as if the OP (as with many new photographers) overestimated the amount of light in an ambient indoor setting and was getting resultant very slow shutter speeds.
thecdmule2 - as Stone 13 said, indoor light which seems entirely adequate to our eyes appears very dim to a camera. Sports shooters often have to use high ISOs and very "fast" (wide aperture) lenses to shoot in indoor gyms, which usually appear plenty bright to the human eye. The lighting in most homes necessitates a high ISO and/or use of a flash to brighten things up enough that the camera isn't "starving for light" for an exposure. Try working through some of the shots in Understanding Exposure outdoors in daylight, you'll have much better luck!
...So does that mean I should avoid slower speeds like 1/4? I hate rules, I dont want to be scared to use a setting, I want to embrace them.
Now you sound like my wife!!! Feel free to experiment with settings - worst you'll have to do is delete the image because it's a blurry mess (which it most likely will be if you handhold your camera at a 1/4 second shutter speed). The "rule" you're talking about is a recommendation to avoid seeing the effects of camera shake in your images. If you put the camera on a tripod or rest it on a sturdy object and use the 2-second timer, you can get away with those kind of shutter speeds....handheld, you're going to have a big mushy blur. Experiment with it and you'll understand why the "rule" (recommendation) exists.
