The Dorr White Balance Lens Cap 52mm gives accurate white balance, as a cameras internal white balance is often inaccurate. The White Balance Cap also serves as a lens cap and may always remain as a protection in front of the lens.
White balance is incredibly important for all photographers who want to get consistant, accurate results with their digital camera. Colour temperature fluctuates from place to place, or even person to person, so a beautifully exposed portrait shot can be created one minute and then completely changed the next minute without any obvious change in ambient light. By using a white balance cap, the white balance of the camera is set for the duration of the shoot, or if there is a custom mode for the camera, forever, thereby taking the worry out of light balance and colour temperature. It simply fits onto the front of the lens whilst the white balance is set on the camera and then removed for the rest of the shoot. Perfect for anyone who needs consistancy and peace of mind.
