Importing Rotations - Different Camera XYZ

Hello,

I am trying to work with camera positions and rotations exported from Applanix POSPac software and have run into an issue. 

The omega-phi-kappa angles from POSPac rotate from the mapping frame X(E), Y(N), Z(up) to the photo frame: X(pointing to right of photo), Y(pointing to left, Z(pointing up from ground to image).

When imported into ContextCapture, the images are all looking up towards the sky. There is obviously a difference in how the POSPac rotation is defined, and what Bentley is expecting however I cannot find any documentation of what Bentley is expecting to further troubleshoot.

Any tips would be great,
Josh
