Photography A – Z the Easy Way: O – Overexposure
Overexposure is a term often discussed in photography. What does it mean?
Simply put, it is when too much light is allowed to reach the sensor and the resulting image is too “light” or “bright”.
Why does it happen?
To get a decent image, the camera has to select a combination of aperture (the size of the hole in the lens that lets in light) and shutter speed (the length of time the sensor is exposed to the light when taking a picture).
Generally, the camera chooses the correct combination. Sometimes the camera makes a wrong judgement for the scene in front of it OR the photographer chooses settings that are not ideal.
If this happens, too much light can enter the camera and hit the sensor, resulting in overexposure. The “whites” or “highlights” will be burnt out and too bright. Any detail in these areas will tend to be lost.
The cure is to retake the photograph and choose LESS exposure by using a smaller aperture or a faster shutter speed. This can be done either manually by the photographer or automatically by the camera if it has facility for “automatic exposure compensation”. Read the manual to find out.
Your images might also be overexposed if there is a good deal of low light in the scene you are photographing as the camera tries to compensate for the average low light levels by increasing the light hitting the sensor. Alternatively, using flash, especially the in-built flash on compacts and lower end prosumers / SLRs can result in overexposure and “bleaching” of your subjects. In these cases try to compensate using the camera.

Skateboard Information
Here we have some skateboard information on yer actual skateboard, including all you need to know on them. Here are a few facts guys and gals, dudes and dudesses:
The skateboard deck, that is the flat surface of the skateboard, is normally made out of laminated maple. How thick the skateboard is depends on the number of layers that the deck is made out of. The less experienced skateboarder should be more inclined to pick a thick skateboard for ease of balance.
For your skateboard information, the wheels are more often than not made out of polyurethane, and can be sized between 39 to 66 millimetres in diameter.
The front of the skateboard is called the nose, which comprises of the front truck bolts to the end of the board.
The back of the skateboard is called the tail, which comprises of the back truck bolts back to the end of the board.
The wheelbase is basically the distance between the front and the back wheels.
Most skateboards come with grip tape on them, or skateboarders put tape on them when they buy their board. The grip tape is stuck to the deck, and has an abrasive surface to give the skateboarder plenty grip to the board, so that they will not slip off so readily.
So theres some skateboard information for your delectation. It is not that important that you know this information, the main thing is being able to skate on the thing! But it gives you a feel for your board and what you are dealing with, and ya know what they say, knowledge is power.
