Exposure
Why are you using a one second exposure? This is usually reserved for extremely low light levels, or to deliberately cause motion blur.
I don't mean to sound condescending, but it sounds like you don't yet have a firm grasp on the basics of exposure. Please forgive me if I'm wrong. I suggest that you get a copy of "Understanding Exposure" by Bryan Peterson. This is an extremely well-written book, with lots and lots of examples, showing how to achieve a "correct" exposure.
As someone else suggested, it may not be possible to get a one-second exposure in normal daylight, without resorting to neutral density filters. Using the "Sunny 16" rule of thumb, at ISO 100, the normal exposure would be 1/100 at f/16. Since the kit lens goes no smaller than f/32, I believe, you could use a shutter speed no slower than 1/25. To achive a full one second exposure, you would need to be able to set the lens at f/180.
At a given light level, exposure is controlled by three variables: shutter speed, aperture and sensitivity (ISO). As shutter speed goes down, aperture number must go up (smaller opening). As ISO goes up, shutter speed and/or aperture must go up.
For example, at ISO 100, the following shows several equivalent exposures:
1/25 at f/32
1/50 at f/22
1/100 at f/16
1/200 at f/11
1/400 at f/8
1/800 at f/5.6
1/1600 at f/4
1/3200 at f/2.8
As the shutter speed is doubled or halved, the aperture goes up or down by one stop, which doubles or halves the AREA of the aperture opening. In all cases, the equivalent amount of light is allowed to strike the sensor.
Exposure compensation is used to override the exposure combination that the camera chooses. This is necessary, because the camera can't tell which portion of the image you want to be properly exposed and it may guess wrong. In that case, you can dial in the amount of over or under exposure you want. This is used to prevent blown highlights, or to keep detail from being lost in the shadows.
