DV sometimes can not be modulated just follow the will. The White Balance Lens Cap can solve all these problems easily which fits both DC/DV cameras. Also it easily slips on to the front of any appropriately sized lens, or a lens with a protective filter.

Ways of getting white balance:

Set the manual mode for white balance

Attach the lens cap on the top of the lens

Set the focus length to telephoto mode

Aim at the scene of photo source

Keep the white balanced value

Note: After modulating the white balance, remove the cap and you can take better pictures.
