Prescanning

The usual method of operating the Better Light 

camera centers around the tasks of prescanning the 
scene, adjusting parameters to achieve the intended 
image, then scanning the final image. This method 
allows for iteratively adjusting the composition, lighting 
and exposure to give the photographer confidence that 
the image on screen will be the same one captured in the final scan.

Making a Prescan

The digital camera has a significant advantage over film in that representative image data can be 

viewed immediately after the exposure, allowing accurate and repeatable determination of exposure, 
color balance, and tonal range. This enables the photographer to precisely adjust the exposure and 
processing conditions for each image, and to neutralize any unwanted color cast, or to introduce color 
filtration as desired.

In addition to evaluating the preview image visually, a digital spot meter permits the photogra-

pher to accurately measure any point location within the preview image, and a histogram display pro-
vides an overall indication of the distribution of image data values.

There are two types of prescans available; the 

normal prescan 

and the 

fast prescan

. Both types of 

prescans can be initiated by clicking on the 

 button in the main control area.The camera will 

then begin a prescan at the lowest resolution available for your model camera:

 

model 4000 series: 20% (1000 x 750 pixels, 4.2 MB)

 

model 6000 series and Super 6K™ series (1000 x 750 pixels, 4.2 MB)

 

Super 8K™ series (888 x 666 pixels, 3.4 MB)

To give the most accurate representation of the final scan image normal prescans are taken using 

the currently selected 

Line Time, ISO, Color 

and 

Tone 

settings.  The time necessary to complete the 

prescan is displayed above the 

Prescan 

button. 

 

Prescans of images to be captured without a tone curve (the “None 14-bit” tone curve 
selection in the Tone panel) are captured and displayed using the previously selected tone 
curve before switching to “None 14-bit”. This creates better image data and exposure rep-
resentations during the prescan and final scan preparation process. The final scan will be 
made without a tone curve.
