4/14/05— Depth of Field Calculator and White Paper
THE PRINCIPALS OF OPTICS AND PHYSICS IMPACT THE RELATIVE DEPTH OF FIELD IN ANY CAMERA SYSTEM.
The high resolution of the digital scan back has unique characteristics that capture images differently than film emulsions. Read the enclosed article to gain some insight on depth of field. Includes a depth-of-field calculator program.

4/14/05— Field-of-View Calculator
Another stand-alone utility program by Robin Myers to determine the Field of View of the Better Light scanning backs based on a specific lens focal length. Field-of-View angle is provided for Horizontal, Vertical and Diagonal of scanning back format. In addition, the focal length equivalent for standard 35mm and 4x5 formats is provided to determine the lens multiplier for that lens on the scanning back.

12 K Stuffit .SIT File. This simple utility can be used with your Better Light camera system to quickly make a plain
text file containing the header information for every image stored on the scan back's own disk drive. The resulting text
file can then be opened, modified, and/or printed using any text editor. This will allow a scan back user to make a
printed record of all images on the scanning camera's disk drive, for future reference.

The “Prescan Images” can be used for sales demonstration or pre-purchase examination of ViewFinder’s features and functions. All controls are functional and you will see live changes for color balance, tone curve and ISO, etc., just as if shooting in the studio. The focus verification will not operate, since it requires the insert's sensor.

TO USE: Open ViewFinder program and hold OPTION [Mac] / ALT [PC] key down and hit PRESCAN button on ViewFinder screen. It will open a dialog box allowing you to locate the preview file(s) you wish to load as the preview image. Download one or more of the Practice Preview Images. Each file has a Macbeth Color Checker™ in the scene to aid color balance and density settings.
