If you have the iXG camera installed on a specialized copy stand – either a Phase One AutoColumn or a Cambo DT AutoColumn - the process will be fully automated as the stand will be able to move the camera the required distance.
The copy stand needs to be calibrated for the AutoPPI feature to work correctly. Click Calibrate in the Copy Stand tool and the camera arm on the column will start moving.
Select the desired Target unit from the drop-down menu, choosing either Resolution (PPI), Field of View (image dimension), Distance or Magnification.
Enter the Target value in the field and click on the button next to it to apply the value. Click on Start.
The AutoPPI feature will autofocus on the target and once the focus is achieved, the camera will move automatically on the copy stand to reach the desired resolution. Finally, the camera will autofocus on the target.
You can double-check whether the Target Resolution is indeed achieved by comparing it to the info under Current Resolution. If that is not the case, click on the button next to the Target value, then click on Start.
- If you select either Field of View or Distance, you can change the units by clicking on the options icon, selecting the Distance unit and choosing either Inch, Millimeter or Centimeter.
- If you need to reuse a certain target resolution, it can be saved for later use as a Preset. Click on the Preset icon and choose Save User Preset… Then save the value. When you select the Preset later, it will be entered into the Target field.
- Make sure that the camera is not positioned too close to the subject. It is better to start with the camera near the top of the copy stand than vice versa.
- It is recommended to position the orange autofocus frame in live view so it covers a high-contrast area as well as being as close to the middle of the subject as possible.
