A separate infrared camera films the person on the dark side's reaction; the two images are combined in post-production.
This is done, in part, by using video editing software to fade the infrared image of the person being revealed to black before they are illuminated, then seamlessly showing the color image of the person being revealed as it is faded in and out.
Will it be love at first sight, or will they leave alone?
This new twist on the ever-popular matchmaking format takes the notion of "blind date" to its literal extreme as Aussie guys and girls have various liaisons in pitch-black conditions over several days. And if so, will they still want to pursue a relationship when they each know what the other looks like?
Three men and three women are sequestered in separate wings of the house, unable to have any conversation or contact with the opposite sex unless in the dark room.
Joining the other on the balcony signifies that the contestants both want to pursue a relationship; exiting the house through the front door signifies that they do not want to pursue a relationship.
Cameras are set up to show both the meeting balcony and the front door.
Throughout the show, the host, Rossi Morreale, provides the men and women with additional insights by providing personality profiles showing which contestants are their best matches and also allowing them to view items the others have brought to the house, such as items of clothing or luggage.
Other episodes include sketch artists drawing contestants' impressions of each other.
