Fringeing in Elements

rating is 2

Anonymous, 18 August 2010 15:25

Fringeing, or Chromatic aberration occurs with some zoom lenses. It happens because the red, green and blue light that makes up a colour image has slightly different wavelengths, and this means the different colours focus at different distances. Correcting the optics within a lens to account for this is fairly straight forward in fixed focal length (prime) lenses, but it’s ...

Understanding reciprocity

rating is 2

Anonymous, 24 October 2007 14:12

When light levels drop, the normal reciprocal relationship between shutter speed and aperture breaks down. In regular daylight conditions, the relationship between the amount of light and the exposure time is constant. So if the light levels halve, you need to double the exposure time to get the same result. However, this rule – known as the reciprocity law – ...

Freeze water droplets in action

rating is 2.5

Anonymous, 24 October 2007 12:56

  The light given out by a flashgun lasts for a tiny fraction of a second, allowing you to freeze action that would otherwise be impossible to capture by simply using a fast shutter speed.

Using a flash diffuser

rating is 2

Anonymous, 24 October 2007 12:49

On-camera flash may be a convenient and affordable way of lighting your portrait shots, but the harsh direct light can make your subject look more like an escaped convict than a film star. Undiffused light comes from a very small point (the tube inside the head of the flash) so it produces very strong directional light. Think of it like ...

How to use a flashmeter

rating is 2.5

You can’t use the camera’s own built-in lightmeter built to meter studio flash exposures:  you’ll need a separate flashmeter to measure the exposure. The most accurate way to use these handheld meters is a technique known as incident light metering. This measures the light falling on the subject rather than the light reflected by it. This means it won’t be ...

Understand your viewfinder

rating is 2.5

Anonymous, 24 October 2007 12:20

  One of the major advantages of an SLR over a compact camera is that the SLR viewfinder shows the same image seen by the lens. However,  not all viewfinders show the entire image that your camera will capture. The viewfinders of most DSLRs only show around 95% of the image that you’re going to capture. Only professional models such ...
