For standard workflow you simply click on the Next button and going on adding your photographs within the software. However, in that wizard there are two submenus called Imports (3) and Additional options (4). Inside the Imports menu you have two options:  Import control points constraints: 3DF Zephyr does not need any pre-calibration file; anyway, if you have a calibration file created with your own equipment, you can load the calibration file by selecting this option. By clicking on the Next button you will find a further submenu where you can choose whether: - manually enter each internal and external parameter (for each image); - specify the position and the Euler angles; - import internal and external parameters using a text file;  Import camera position constraints: as the previous option, this one allows you to import camera position (by loading a txt file) in 3DF Zephyr and to use them to constrain the 3D reconstruction; a standard example of practical usage of this entry is represented by the pictures taken by drone or UAV system record recording GPS coordinates of the shots into the Exif data. In the Additional options submenu (4) you can specify the software to perform each of the four 3D reconstruction phases without stopping between a phase and the other one; this tool can be very helpful when you don't have enough time to set your 3D reconstruction in details . This technique is called batch processing and is only recommended for advanced users, as it represents the highest level of automation in 3DF Zephyr.
