HASSELBLAD H1 Gray Balance Function
The H1 camera has a built-in gray balance
function. Select the "Gray bal. exp." option under
the "User button function" in the "Custom
Settings" sub-menu and press the Save button to
assign the function to the User button. Focus the
H1 on a neutral object so that the object fills the
central spot on the viewfinder screen. Press and
hold the H1 User button and an image will be
captured. The DCS 645H will automatically
perform its Click Balance function, using the
image data from the central spot area of the
image. The subsequent White Balance value will
be used on all subsequent images, until a new
White Balance choice is made.
Long Exposure
The Long Exposure property reduces
accumulated pattern noise in long exposure
images. When you set this property
(page 78) ,
long exposure processing is applied to
subsequently captured images.
