Lights, cameras, action!
OK, just lights - what lights make your home feel more cosy? What lights make your kitchen feel bright? Consider extra uplighters and lamps around your home and get them switched on to suit your home. If you've got a dark room, putting several lamps on can add the feeling of light and welcoming to people coming to view your home.
Bright lights are good in the kitchen and bathroom but most other rooms benefit from soft mood lighting, layers of light giving a feeling of depth and space to a room.
Play around with lights - and when you've got it right, make a note. Then when you have people come to view your home you can revert to staged lighting and help them see your home in a great light!
