Compact Digital Cameras – How Flash works.
All compact digital cameras will have a flash attached to their body. In compact digital cameras it may only be a small, low powered unit. Whilst not always that powerful, one advantage to the inbuilt flash unit is that the exposure and flash output can be set automatically. Even a small flash will have an use. Whilst the most obvious role that comes to mind is to allow the photographer to make a shot indoors in low light, they do have another use. They are a great means to reduce harsh shadows in bright sunlight. A flash will ‘fill in’ the shadows caused by harsh sunlight and can ‘lift’ an image. When used properly, a flash can improve your photograph, but use it incorrectly and your compact digital cameras flash can ruin your photograph. There can be problems with having a flash unit attached to the camera itself. This is a common fault known as ‘red eye’ that can be found within your photographs. Red eye occurs when the light from the flash unit, on compact digital cameras, bounces directly into your compact digital cameras lens from your sitter’s eyes. It works much in the same way as the ‘cat’s eyes’ you see in the road. The fact that the flash unit is placed so near the camera lens accentuates the problem. Your compact digital cameras ‘red eye reduction’ mode will serve to reduce the problem or you can often get rid of it in software later.
