Lesson 3 – Exposure: High Key

A picture is essentially high-key white on white. This style of photography gives an impression of lightness and clarity. Typically what happens is the camera wants to make the white of the photo - no dark areas to "balance" of the exhibition - too dark. So you know has turned gray. You may have seen, especially when shooting a snowy field on a gray day. However, to expose high key is quite simple.With a camera in meters, you can measure the light hitting a white area and two open cases such as changing the opening to ƒ11 ƒ5.6.
Exercise: Put a large sheet of white paper or white cloth on a table near a large window to the north, lay an egg in the middle. Take a picture with exposure in the camera meter suggests. You may need to use a tripod the camera does not shake when the shutter speed is too slow.
Described in the top of this page - meter next to a white surface and open two stops. Compare photos.
This can be good for other scenarios, the exhibition is a delicate thing - like weddings where the bride wears white and the groom is black. Winds often with the dress no detail is blown into the clothing. By measurement of the dress and the development of two stations, you can prevent this.
You can also use a handheld device, the light strikes the subject, the more accurate than the value measured in camera meters.
Note: Please note that some digital cameras built exposure to avoid overexposure. If the exposure is too much to do could be "blown" and details are lost int the brightest areas of the image. By artificially "darkening" of the image, the camera manufacturers try to ensure that risks are not too bright. This does not affect all cameras, but it seems to be the case for some. This means that exposure in Class 2, 3 and 4 may require somewhat higher than suggested in the lesson. Maybe you use the method "on the right side to expose."
