Five Steps:
1) Format card
2) Clear Settings
3) File type/ Quality
4) White balance - WB - AWB
5) ISO (International Organisation for Standardisation)
ISO in traditional (film) photography ISO (or ASA) was the indication of how sensitive a film was to light. It was measured in numbers. The lower the number the lower the sensitivity of the film and the finer the grain in the shots you’re taking. In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain. Higher ISO settings are generally used in darker situations to get faster shutter speeds. For example an indoor sports event when you want to freeze the action in lower light.
Aperture - aperture is a hole within a lens, through which light travels into the camera body. The iris of the lens that controls the size (diameter) of the aperture is called “diaphragm” in optics. The sole purpose of the diaphragm is to block or stop all light, with the exception of the light that goes through the aperture. In photography, aperture is expressed in f-numbers (for example f/5.6). These f-numbers that are known as “f-stops” are a way of describing the size of the aperture, or how open or closed the aperture is. A smaller f-stop means a larger aperture, while a larger f-stop means a smaller aperture. Most people find this awkward, since we are used to having larger numbers represent larger values, but not in this case. For example, f/1.4 is larger than f/2.0 and much larger than f/8.0.
Shutter speed - shutter speed is ‘the amount of time that the shutter is open’. Shutter speed is measured in seconds – or in most cases fractions of seconds. The bigger the denominator the faster the speed (ie 1/1000 is much faster than 1/30).
I have experimented with different shutter speeds, ISO and aperture, although not to any success.
