NuvoFocus has three sheets; PROG, DATA and CALC. CALC is protected and cannot be viewed.
Cells that are shaded in Light Blue is for user INPUT and in Light Yellow is calculated OUTPUT.
You enter data only once, when you first start. Select prefered Unit of Distance, meter or feet. All measurement should be in decimal. NOT 5 feet 2 inch, BUT 5.17 feet.
Next, enter DB and Lens information. Up to 5 lenses data maybe entered. For Free Trial Version, first two spaces are reserved for SK35XL, one for AS RM mount and another for ALPA (or Cambo) mount with HPF ring, and Lens Equations are pre-installed.
Try to get an accurate data for lens focal length. SK35XL has nominal focal length of 36.4 mm instead of 35 mm according to their data sheet.
Select the type of Lens Mount; AS RM or ALPA (or Cambo). I made a BIG assumption that no one would have both AS RM camera and ALPA (or Cambo) camera.
In Trial Version, lens # 1 is AS RM mount and lens # 2 is ALPA (or Cambo) mount.
Select a lens to be used. The same lens is assumed for both DOF and Lens Tilt Calculation.
Select CoC as # of pixel pitch. It can be any number, ie, 2 or 3.3 or 1.4142. The same CoC value is used for LENS/CAMERA Tilt calculation.
All distance measurement should be done with a Disto mounted on a tripod or on camera, especially, if you want to do Lens/Camera Tilt. You have to measure two distances once Disto is mounted; the horizontal distance between Disto sensor and DB sensor and the vertical distance between the axis of camera lens and Disto Sensor. The program expects you to enter the 'horizontal distance offset' into a Disto. My setup has 50 mm distance between Disto sensor and DB sensor, so I entered 50 mm as OFFSET into my Disto, and the Disto reading automatically shows the distance between the DB sensor plane and Subject.
One way a Disto can be mounted
A2 in the diagram is the horizontal distance between Disto sensor and DB image sensor, D is tripod height and C is the distance between Lens Axis and Disto Axis.
Enter the height of Tripod and the vertical distance between the two axis, Disto and camera lens. My set up has 119 mm distance between two axis. The camera height is calculated by adding these two numbers.
Now make two distance measurement using a Disto, Near and Far Subject (both horizontal and vertical distance). Learn how to do it by reading Disto Manual pg 11, 'Direct Horizontal Distance'.
Enter Camera Tilt Angle (if you are tilting the camera in addition to the lens tilt). The program use the convention that the tilt angle is POSITIVE when the camera is tilted forward (however, Disto displays forward tilt as a negative value).
The program provide the required Lens Tilt Angle and the focus distance. It also calculate the Wedge of Dof at a specific distance.
The program will display the message, 'Indexed Focus is not abled for this lens' if you select other the lenses without Lens Equation (Lens # 1 (with AS RM camera) or Lens # 2 (with ALPA (or Cambo) HPF mount with Trial version).
INDEXED FOCUS SETTING
With this option abled, all calculated and/or measured subject distance will be displayed in simple and easy to use Index Numbers.
OUPUT with AS-RM mount Lens
HFD, Subject Distance, Target Distance with Near/Far DoF and Lens /Camera Tilt Subject Distances are displayed in both in distance measurement unit (meter or feet) and also in AS-RM Focus Index, including the Color designations.
OUTPUT with ALPA (or Cambo) HPF Ring Lens
Again, HFD, Subject Distance, Target Distance with Near/Far DoF and Lens /Camera Tilt Subject Distances are displayed in both in distance measurement unit (meter or feet) and also in in degree of rotation (0 - 270).
