A new invisible flash technology could revolutionise the way photos are taken using digital cameras, such as Panasonic Lumix or Canon Ixus models.
New York University researchers Dilip Krishnan and Rob Fergus claim to have developed a new flash that does not subject those nearby photographers to an intrusive flash glare when they take a picture.
The flash functions by using invisible parts of the light spectrum to illuminate subjects and landscapes when photographers want to take pictures in poorly lit environments.
In order to produce its effect, UV and IR camera filters must also be removed.
However, photographs do not quite provide a true representation of the lighting and do not pick up any colour.
The pair of scientists claim that this invisible flash picture must be followed immediately afterwards by another picture without any flash at all.
By using a new technique to combine the two images, a composite picture can be created that provides an even light balance with colours.
