Are you ready some PHOTOGRAPHY!

The Nikon D4 has arrived and just in time, my friends!!!

 

the D4 uses a 16.2 megapixel sensor ideal for capturing fast-moving subjects. The camera captures 11 frames a second, with an ideal ISO range of an incredibly low 50 to as high as 12,500, with boosts of up to 204,800. 51 points of auto-focus help you get your target sharp, and the D4 supports standard CF and the new QXD cards for photo storage.

 

Engadget discovered that the Nikon D4 and D800 will be available in France this March. The D4 will launch first on the 15th, followed by the D800 on the 22nd, and the D800E in April. Nikon PR later confirmed that the D4 will also be available in the U.S. sometime mid-March, but they did not give any confirmation for the D800 or D800E.

What is Exposure? 

 

Exposure is the amount of light collected by the sensor in your camera during a single picture.  If the shot is exposed too long the photograph will be washed out.  If the shot is exposed too short the photograph will appear too dark.  Almost all cameras today have light meters which measure the light in the given shot and set an ideal exposure automatically

 

The two primary controls your camera uses for exposure are shutter speed (the amount of time the sensor is exposed to light) and aperture (the size of the lens opening that lets light into the camera).  Shutter speeds are measured in seconds and more commonly fractions of a second. (1/2000 of a second is very fast and 8′ seconds is extremely slow).  Apertures are measured in something called f/stops (a very wide aperture is f/2.8 and a very small aperture is f/19).

 

Shutter speed for example can be used to freeze subjects in midair with a fast speed or it can be used to blur water with a slow speed.

 

Aperture controls the depth-of-field which is what is in focus in the picture.  Aperture can be used to draw attention to one subject (like the flower on the right) by blurring the background with a wide aperture (low f/stop).  Aperture can also be used to focus everything in a picture with a narrow aperture (high f/stop).
